How to Send and Receive MMS in Android:
This is a guide I am creating to help all of you out there making messaging apps like sliding messaging, hopefully it will help someone at least get started in the right direction! This guide will not be a guide on how to read MMS messages, which is actually very simple. Here is a tutorial on that which will get you started: How to read MMS data in Android (The first answer is a lifesaver, it will get you where you need to go). Now onto sending and receiving!
First off, I want to say that all of this may seem very daunting, especially to a first time, independent Android app developer like I was when this started out, trying to manange time between this and college studies! A messaging app can be extremely difficult to write since there is no supported API to it at all and you have to go through lines and lines trying to decipher stock source code. Stick to it and you can definitely get there eventually I do feel that Google should add this type of thing into their API and document it though, so as to make it easier for us 3rd party developers without a giant team behind us! Come on Google!
Here's the steps in the order that I went through:
1) You need to import a lot of internal android classes, which can all be found here: GrepCode
Here are all of the files you will need to grab (there may be more, but I was able to in the end modify all of these files so that they don't depend on others such as taking out unnecessary lines of code, etc)

Whew, that was a ton of typing, hopefully its worth it! Haha. May be some typos in there too, but I'm sure you will be able to find the right one.
I know that's a lot, but I found it to be the easiest way of doing things. I'm not actually sure that all of these are required, and I may have missed a couple or added a couple extras, but you get the picture at least and thats most of them. You'll probably only end up using about 10% of those files, but since they all have others imported, I chose to import them all instead of the possibility of messing something up that was necessary. Like I said, its a lot, but almost all of them are really small so they won't increase the size of your app by more then half a megabyte at max (not sure on an exact number) so that's not really something to worry about. If you can make it by this daunting task, you should be good to go for the rest of the tutorial.
2) You need an MMS Part class that will be used to store MMS data you are going to be sending. Here is what mine looks like:
Code:
public class MMSPart {
public String Name = "";
public String MimeType = "";
public byte[] Data;
}
Just copy and paste this class.
Very straightforward as to what this will do for you, it is the actual file that we will be sending through out http connection. MimeType is the type of object that the part is, for example image/png or text/plain are the 2 that I use.
3) Next up, we need a class that will assist us in finding the system APNs. Here is mine:
Code:
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.provider.Telephony;
import android.text.TextUtils;
import android.widget.Toast;
public class APNHelper {
public APNHelper(final Context context) {
this.context = context;
}
@SuppressWarnings("unchecked")
public List<APN> getMMSApns() {
final Cursor apnCursor = this.context.getContentResolver().query(Uri.withAppendedPath(Telephony.Carriers.CONTENT_URI, "current"), null, null, null, null);
if ( apnCursor == null ) {
return Collections.EMPTY_LIST;
} else {
final List<APN> results = new ArrayList<APN>();
if ( apnCursor.moveToFirst() ) {
do {
final String type = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.TYPE));
if ( !TextUtils.isEmpty(type) && ( type.equalsIgnoreCase("*") || type.equalsIgnoreCase("mms") ) ) {
final String mmsc = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSC));
final String mmsProxy = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPROXY));
final String port = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPORT));
final APN apn = new APN();
apn.MMSCenterUrl = mmsc;
apn.MMSProxy = mmsProxy;
apn.MMSPort = port;
results.add(apn);
Toast.makeText(context, mmsc + " " + mmsProxy + " " + port, Toast.LENGTH_LONG).show();
}
} while ( apnCursor.moveToNext() );
}
apnCursor.close();
return results;
}
}
private Context context;
}
Also, you will need an APN class, here is what that one looks like:
Code:
public class APN {
public String MMSCenterUrl = "";
public String MMSPort = "";
public String MMSProxy = "";
public APN(String MMSCenterUrl, String MMSPort, String MMSProxy)
{
this.MMSCenterUrl = MMSCenterUrl;
this.MMSPort = MMSPort;
this.MMSProxy = MMSProxy;
}
public APN()
{
}
}
Just copy and paste these classes.
The problem with this is that in Android 4.0 and up, Google blocks 3rd party access to APNs (though from trial and error I believe that you can access them on some touchwiz roms/phones, but not all). To get around this, in Sliding Messaging I had to have users input this information manually, so if you have users who will be on an API higher than 14 (ICS), you will need to have this option or it WILL ABSOLUTELY NOT work. At all. A little further down I'll show you how to implement so that you can try and find APNs, and if it fails then you can set them manually.
4) You need to include these permissions in the app for things to work and not get FCs because of lack of permissions:
Code:
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_MMS" />
<uses-permission android:name="android.permission.READ_SMS"/>
<uses-permission android:name="android.permission.WRITE_SMS"/>
<uses-permission android:name="android.permission.WRITE_APN_SETTINGS" />
Just put them in the AndroidManifest with the rest. If you can't figure this step out maybe its time to start with something a little easier
As for the last one, write apn settings, I know for a fact you will not be able to compile your app through eclipse if you include it and you are working with Android 4.0+. It can only be applied to system apps only for API 14 and up and I don't know if you can include it without error if you are only targeting Gingerbread or not. More then likely you will have to take it out if you are not compiling your app as a system app by building it with the rest of the android source.
Please Note: I'm not actually sure that the internet permission is necessary, but the stock google app has it so I decided to include it.
5) Ok, now we have all of our classes we will use and it is time to send an MMS message. I will just copy the 2 functions that I use to do this directly below, and then explain them after that. Here they are:
Code:
public void sendMMS(final String recipient, final MMSPart[] parts)
{
ConnectivityManager mConnMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
final int result = mConnMgr.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE, "enableMMS");
if (result != 0)
{
IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (!action.equals(ConnectivityManager.CONNECTIVITY_ACTION))
{
return;
}
@SuppressWarnings("deprecation")
NetworkInfo mNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
if ((mNetworkInfo == null) || (mNetworkInfo.getType() != ConnectivityManager.TYPE_MOBILE_MMS))
{
return;
}
if (!mNetworkInfo.isConnected())
{
return;
} else
{
sendData(recipient, parts);
unregisterReceiver(this);
}
}
};
registerReceiver(receiver, filter);
} else
{
sendData(recipient, parts);
}
}
This function is fairly simple. All it does is tell the sytem that we are going to start using a mobile connection and it should connect using the term "enableMMS" so that we start the right type of connection. The variable result is set to the type of connection already active when we call this, and we are looking for it to be set to 0, meaning that our apns are already active. If this is the case, you can just skip right ahead to sending the MMS message. More than likely though, apns will not be active when you start the call, so you need to listen for a change in the connectivity through a broadcast receiver. That is what is going on inside the block of code where (result != 0). Once the receiver gets the correct type of connection, it calls the below function of sendData and unregisters itself so we don't leak receivers.
When the message is ready to be sent:
Code:
public void sendData(final String recipient, final MMSPart[] parts)
{
final Context context = this;
new Thread(new Runnable() {
@Override
public void run() {
final SendReq sendRequest = new SendReq();
final EncodedStringValue[] phoneNumber = EncodedStringValue.extract(recipient);
if (phoneNumber != null && phoneNumber.length > 0)
{
sendRequest.addTo(phoneNumber);
}
final PduBody pduBody = new PduBody();
if (parts != null)
{
for (MMSPart part : parts)
{
if (part != null)
{
try
{
final PduPart partPdu = new PduPart();
partPdu.setName(part.Name.getBytes());
partPdu.setContentType(part.MimeType.getBytes());
partPdu.setData(part.Data);
pduBody.addPart(partPdu);
} catch (Exception e)
{
}
}
}
}
sendRequest.setBody(pduBody);
final PduComposer composer = new PduComposer(context, sendRequest);
final byte[] bytesToSend = composer.make();
List<APN> apns = new ArrayList<APN>();
try
{
APNHelper helper = new APNHelper(context);
apns = helper.getMMSApns();
} catch (Exception e)
{
APN apn = new APN(sharedPrefs.getString("mmsc_url", ""), sharedPrefs.getString("mms_port", ""), sharedPrefs.getString("mms_proxy", ""));
apns.add(apn);
}
try {
HttpUtils.httpConnection(context, 4444L, apns.get(0).MMSCenterUrl, bytesToSend, HttpUtils.HTTP_POST_METHOD, !TextUtils.isEmpty(apns.get(0).MMSProxy), apns.get(0).MMSProxy, Integer.parseInt(apns.get(0).MMSPort));
ConnectivityManager mConnMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
mConnMgr.startUsingNetworkFeature(ConnectivityManager.TYPE_MOBILE_MMS, "enableMMS");
IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Cursor query = context.getContentResolver().query(Uri.parse("content://mms"), new String[] {"_id"}, null, null, "date desc");
query.moveToFirst();
String id = query.getString(query.getColumnIndex("_id"));
query.close();
ContentValues values = new ContentValues();
values.put("msg_box", 2);
String where = "_id" + " = '" + id + "'";
context.getContentResolver().update(Uri.parse("content://mms"), values, where, null);
context.unregisterReceiver(this);
}
};
registerReceiver(receiver, filter);
} catch (Exception e) {
Cursor query = context.getContentResolver().query(Uri.parse("content://mms"), new String[] {"_id"}, null, null, "date desc");
query.moveToFirst();
String id = query.getString(query.getColumnIndex("_id"));
query.close();
ContentValues values = new ContentValues();
values.put("msg_box", 5);
String where = "_id" + " = '" + id + "'";
context.getContentResolver().update(Uri.parse("content://mms"), values, where, null);
((Activity) context).getWindow().getDecorView().findViewById(android.R.id.content).post(new Runnable() {
@Override
public void run() {
Toast.makeText(context, "MMS Error", Toast.LENGTH_SHORT).show();
}
});
}
}
}).start();
}
This function is where all the magic happens. First, we need to create a new thread to run on because you can't access an HTTP connection on the UI thread (I ran into this error the first time around since I had never worked with data connections before). Once that thread is running, we create a new SendReq object which is what we will be sending through the http request. You will need to encode your recipient (this part of the code can also be used to support group messaging, but I have not included that code, you will need to write it yourself if you so choose. You can attach multiple addresses by calling sendRequest.addTo() multiple times) and attach it to the sendRequest. Next up, attach your MMSPart file using a for loop. Here is how to initialize that MMSPart to whatever you want to include in it:
Code:
Bitmap b = ________; // Whatever your bitmap is that you want to send
ByteArrayOutputStream stream = new ByteArrayOutputStream();
b.compress(Bitmap.CompressFormat.PNG, 100, stream);
byte[] byteArray = stream.toByteArray();
MMSPart[] parts = new MMSPart[1];
parts[0] = new MMSPart();
parts[0].Name = "Image";
parts[0].MimeType = "image/png";
parts[0].Data = byteArray;
Using this, you can also add text to the request with the mimetype "text/plain" and encode text as a byte array so that it can be attached in the same mannor. I won't post that code, you should be able to figure it out.
Back to the original sendData function, we can now attach the pduBody which includes all of the byte arrays that we want to send, in this specific case, just an image and no text. After that, all that is left is to actually create the byte array to send, bytesToSend, which can be done very easily through internal classes.
Now we are ready to make the actual send request, which must be done through the users APNs using an http_post method. But first, we need to retrieve APNs. As I said earlier, if a user is running an Android version less then 4.0, then the app should be able to get the system defined APNs through the APN helper class that I provided (still no promises on this though as it has been untested, I don't have an old phone anymore to test on). Surround the request to APNHelper with a try/catch block so that we can catch the error of insigificant permissions, and then apply your user defined custom APNs that will actually work. I have users enter these in settings, thats why you see them being set through sharedPreference strings. you can manually type in whatever strings you want to for your network during testing phases though and that should work fine, just remember different networks use different APNs.
Ahh finally we are ready to make our Http request. This is fairly simple, as it is just one line of code which you should be able to directly take from my example if you initialize apns the same way I have:
Code:
HttpUtils.httpConnection(context, 4444L, apns.get(0).MMSCenterUrl, bytesToSend, HttpUtils.HTTP_POST_METHOD, !TextUtils.isEmpty(apns.get(0).MMSProxy), apns.get(0).MMSProxy, Integer.parseInt(apns.get(0).MMSPort));
You can look at javadocs for this function if you want to know what all of this is, but just know that it will make a post request through your MMSC you have defined and then send the message through the proxy and port (if those are needed, some carriers do not require them). Also, remember to add a catch block around this in case the sending fails for whatever reason, and tell your users that the request has failed. In this example, when the message fails to send, it moves the message to msg_box = 5, which is where MMS with errors are stored. This is simply updating the database with a new location for our recently failed message.
Last thing we have to do is listen for when the message has sent. This is where I've completely made up a function, and it functions correctly for ALMOST everyone (the only people not so far are Sprint users, and I haven't found a way around it yet). To do this, after our request, we register a new connectivity receiver just as we did when we were preparing to send a message, and this time around, when the state of the phones internet connection changes - usually dropping out of the APN request space I believe - we can move the message from the outbox to the sent message box and boom, message sent.
Yay, you should have just been able to send your first MMS message! (Unless I forgot a step in there lol) That's exciting stuff! Notice now though, that although you sent the message (and you have coded in how to change which message box the message is in), the message didn't get saved to the database so you can't actually see it in the app. That doesn't do most of us any good, so next step is how to save it to the SMS database on your phone.
6) Here we save the message, I'll just list out the functions again and then explain them after that:
Code:
public static Uri insert(Context context, String[] to, String subject, byte[] imageBytes)
{
try
{
Uri destUri = Uri.parse("content://mms");
// Get thread id
Set<String> recipients = new HashSet<String>();
recipients.addAll(Arrays.asList(to));
long thread_id = Telephony.Threads.getOrCreateThreadId(context, recipients);
// Create a dummy sms
ContentValues dummyValues = new ContentValues();
dummyValues.put("thread_id", thread_id);
dummyValues.put("body", "Dummy SMS body.");
Uri dummySms = context.getContentResolver().insert(Uri.parse("content://sms/sent"), dummyValues);
// Create a new message entry
long now = System.currentTimeMillis();
ContentValues mmsValues = new ContentValues();
mmsValues.put("thread_id", thread_id);
mmsValues.put("date", now/1000L);
mmsValues.put("msg_box", 4);
//mmsValues.put("m_id", System.currentTimeMillis());
mmsValues.put("read", 1);
mmsValues.put("sub", subject);
mmsValues.put("sub_cs", 106);
mmsValues.put("ct_t", "application/vnd.wap.multipart.related");
if (imageBytes != null)
{
mmsValues.put("exp", imageBytes.length);
} else
{
mmsValues.put("exp", 0);
}
mmsValues.put("m_cls", "personal");
mmsValues.put("m_type", 128); // 132 (RETRIEVE CONF) 130 (NOTIF IND) 128 (SEND REQ)
mmsValues.put("v", 19);
mmsValues.put("pri", 129);
mmsValues.put("tr_id", "T"+ Long.toHexString(now));
mmsValues.put("resp_st", 128);
// Insert message
Uri res = context.getContentResolver().insert(destUri, mmsValues);
String messageId = res.getLastPathSegment().trim();
// Create part
if (imageBytes != null)
{
createPartImage(context, messageId, imageBytes);
}
// Create addresses
for (String addr : to)
{
createAddr(context, messageId, addr);
}
//res = Uri.parse(destUri + "/" + messageId);
// Delete dummy sms
context.getContentResolver().delete(dummySms, null, null);
return res;
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
Code:
private static Uri createPartImage(Context context, String id, byte[] imageBytes) throws Exception
{
ContentValues mmsPartValue = new ContentValues();
mmsPartValue.put("mid", id);
mmsPartValue.put("ct", "image/png");
mmsPartValue.put("cid", "<" + System.currentTimeMillis() + ">");
Uri partUri = Uri.parse("content://mms/" + id + "/part");
Uri res = context.getContentResolver().insert(partUri, mmsPartValue);
// Add data to part
OutputStream os = context.getContentResolver().openOutputStream(res);
ByteArrayInputStream is = new ByteArrayInputStream(imageBytes);
byte[] buffer = new byte[256];
for (int len=0; (len=is.read(buffer)) != -1;)
{
os.write(buffer, 0, len);
}
os.close();
is.close();
return res;
}
Code:
private static Uri createAddr(Context context, String id, String addr) throws Exception
{
ContentValues addrValues = new ContentValues();
addrValues.put("address", addr);
addrValues.put("charset", "106");
addrValues.put("type", 151); // TO
Uri addrUri = Uri.parse("content://mms/"+ id +"/addr");
Uri res = context.getContentResolver().insert(addrUri, addrValues);
return res;
}
I didn't write these functions, credit to Vodemki on Stack Overflow. All you have to do is call the insert function and it will do all of the work for you. Send that fuction the activity context, a string array of the numbers who you sent the message to, a subject for the message, and the same byte array of the image you passed earlier to your MMS part file. You can look at the code for inserting the image and reproduce this to do the same for a string of text you are sending with the image.
You will want to actually call these funtions right after you push the send button for example, to first save the message and then you can send it and update it later after it has sent or failed to send.
Ok, now that will successfully allow you to put the MMS message in the database. For some reason, these messages just show up as blank messages in the stock app, not sure why, but Sliding Messaging is able to read them at least, so depending on your implementation, yours should be able to do so as well.
Now all this function does is insert the image. I don't want to give away all of my secrets for Sliding Messaging so you will have to go through and find out how to insert text and group message addresses yourself, I think that's fair enough and if you've made it this far in your app, you shouldn't have to much of a problem with it
Wow, we just sent and saved that message to our phone, that means we are halfway home! (Nice rhyme huh )
Onto receiving in the next post.
7) First up, you'll have to know a little something about querying the mms-sms database, read up on that first if you haven't already (first link I have posted at the top). This is all out of my brain and what I was able to do from experience, and seems to work very well... you won't find a tutorial anywhere else on the internet of how to do this (at least I couldn't anywhere). I'm not going to just give you a simple function for this one though, you will have to adapt the code according to how you want it to be used. Once again, here is the code you will need to use:
Code:
id = ________; // this is the id of your MMS message that you are going to search for
Cursor locationQuery = context.getContentResolver().query(Uri.parse("content://mms/"), new String[] {"m_size", "exp", "ct_l", "_id"}, "_id=?", new String[]{id}, null);
locationQuery.moveToFirst();
String exp = "1";
String size = "1";
try
{
size = locationQuery.getString(locationQuery.getColumnIndex("m_size"));
exp = locationQuery.getString(locationQuery.getColumnIndex("exp"));
} catch (Exception f)
{
}
String location = locationQuery.getString(locationQuery.getColumnIndex("ct_l"));
The above function is where you query the message you are interested in downloading, and get data from it such as expiration date, size, and location on a server. The date will be a date in milliseconds that you can format accordingly and display to the screen if you so choose, and the size will be in bytes, but you will probably want to convert to kb by dividing by 1000. As for the location, that is what we are going to use to download the message:
Code:
List<APN> apns = new ArrayList<APN>();
try
{
APNHelper helper = new APNHelper(context);
apns = helper.getMMSApns();
} catch (Exception e)
{
APN apn = new APN(sharedPrefs.getString("mmsc_url", ""), sharedPrefs.getString("mms_port", ""), sharedPrefs.getString("mms_proxy", ""));
apns.add(apn);
}
Get your APNs the same way as we did before when sending, I won't explain this again.
Code:
try {
byte[] resp = HttpUtils.httpConnection(
context, SendingProgressTokenManager.NO_TOKEN,
downloadLocation, null, HttpUtils.HTTP_GET_METHOD,
!TextUtils.isEmpty(apns.get(0).MMSProxy),
apns.get(0).MMSProxy,
Integer.parseInt(apns.get(0).MMSPort));
RetrieveConf retrieveConf = (RetrieveConf) new PduParser(resp).parse();
PduPersister persister = PduPersister.getPduPersister(context);
Uri msgUri = persister.persist(retrieveConf, Inbox.CONTENT_URI, true,
true, null);
ContentValues values = new ContentValues(1);
values.put(Mms.DATE, System.currentTimeMillis() / 1000L);
SqliteWrapper.update(context, context.getContentResolver(),
msgUri, values, null, null);
SqliteWrapper.delete(context, context.getContentResolver(),
Uri.parse("content://mms/"), "thread_id=? and _id=?", new String[] {threadIds, msgId});
((Activity) context).getWindow().getDecorView().findViewById(android.R.id.content).post(new Runnable() {
@Override
public void run() {
Toast.makeText(context, "Message Received", Toast.LENGTH_SHORT).show();
}
});

This request is much the same as the previous we used when sending the message, except this time we use a get request instead of post, send the funtion a null where before it was out bytesToSend array, and receive a byte array from it. Once you have received this byte array, you can easily use internal classes to save the message to the database (these messages are saved 100% correctly and will show up in the stock app once downloaded, unlike before) and then delete the old message stored there that only had location data for the message to be downloaded. I won't go into much more detail then that, it should be easy enough to understand just from the code.
I have this function tied to a button press, but in theory you should also be able to register a WAP_PUSH_RECEIVED broadcast receiver that saves the message automatically when your phone gets one (WAP is the type of broadcast you get when receiving MMS data). I'm not going to post anything here about that because I haven't done it, but if you want, all of the code is the same and you can easily base it happening off of a setting in your app and the network connectivity state when the message is received.
Another Note: There is probably a way to use the above code with persisters etc to be able to save an MMS to the database in a much easier way, but I haven't looked into that at all, mostly because the code I posted in step 6 works just fine and I don't see a need for much else if you can handle just copying and pasting those functions.
Now I think that may be it... we covered sending MMS, saving sent MMS and finally receiving MMS! Fun stuff!
In conclusion, I just want to give something back to the community that has given my app, Sliding Messaging, so much love over the past couple of months. I hope this helps someone out there, because as far as I know and could find, this is the only full MMS tutorial there is for Android (and the only one at all for actually downloading MMS from the internet) and should get everything done that you need! Ask any questions you want and feel free to PM me if you need more assistance.
Now no one out there should have any excuse for not including at least some MMS support in your messaging apps! Hopefully this will save you from days upon days of research to no avail on the subject and unjust criticism from people who know absolutely nothing about the topic like I did (Had one person tell me to f-off and if I couldn't get it working, then his $0.99 entitled him to say that I needed to hire someone else who was actually competent at programming and spend all of my college savings so that person would do it for me ... to that person I say, HAHA, I did it. lol) Your users will be happy people if you get this implemented!
Also guys, I wouldn't mind getting a little credit if anyone out there uses this tutorial to get things up and running, but its not necessary if you don't want! Instead you could just buy me a beer and donate to me To the people who actually read through these last 3 paragraphs, I say thank you! Hopefully this tutorial can at least get you started, wish I had it reference when I was adding the support in!

grepcode files missing
I tried to download classes from your given link 'Grepcode'.
It is missing the contents of com.google folder even it do not contain folder named google in com folder. (i tried different versions like 4.2.1,4.2.2 etc .. still same problem )
can you give me any other link to download classes ?
Cool, thanks.
(You might want to add [Guide] to your thread title. For now it looks like a question. )
Thanks very much for doing this. Had to do a bit of searching on the internet for some of the files, and some of the functions needed slight modification but this was enough of a push in the right direction that I've got mms sending working. Great job and good luck with the continued success of your app!
Also- your responses on the android marketplace to people leaving stupid feedback make me laugh!
Getting Connection Refused error
Hi,
I tried your code. I am getting the APN settings perfectly. But a soon as the httpClient tries to connect to my MMSC it throws ConnectionRefused Error.
Please help me. Its been head-scratcher 3 days in a row now.
Thanks. in advance.
Please help
I am not able to import the classes with name
com.android.mms.*
and
com.google.*
I downloaded the android-4.2.2_r1.jar and also android-4.4_r1.jar
But these jars do not contain all required classes.
Please help how to add these classes.
Regarding the missing classes
Hi,
I am looking for a solution to programmatically sending MMS through my Android Application.
Some classess are missing(com.google.*) in the jar downloaded from grepcode.
Can anybody help in this regard?
Thanks.
Missing Function
hi
When I want to insert MMS message in DB, eclipse says "Telephony.Threads.getOrCreateThreadId" is undefined!
What should I do?
Thanks
CursorIndexOutOfBoundsException
hi ,
I get exception like this
android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0
AS per yourCode
Cursor query = context.getContentResolver().query(Uri.parse("content://mms"), new String[]
{
"_id"
}, null, null, "date desc");
query.moveToFirst();
String id = query.getString(query.getColumnIndex("_id"));
get force close when i try to get id
Does this still work? I noticed a lot of the comments say there are missing stuff. I need a good tutorial for implementing MMS sending/ receiving.
I know this feature or activity is pretty much useless in android 4.0+ but I still like the idea of managing Launchers in your rom.
How would one go about displaying the Launchers installed in their system and when clicked, launches the launcher selected? Even maybe delete/ manage them?
Almost like how LG had Home Managers in their older devices
There is an Intent for the laucher. Google for it.
Then get the PackageManager using
Code:
getPackageManager()
and get all Activities for that Intent by invoking
Code:
queryIntentActivities(Intent intent, int flags)
on the PackageManager (for flags use 0).
If you want to launch them, get the ResolveInfo from the list you get by calling the query method and then its activityInfo. You can get the packageName from the field packageName of the ActivityInfo.
Then launch that package by using
Code:
startActivity(getLaunchIntentForPackage(String package))
Ok, found this on Google. Would be even better: http://stackoverflow.com/questions/12504954/how-to-start-an-intent-from-a-resolveinfo

Thanks for the advice! Il see if I can work with this. Id like to incorperate something like this in my future AOSP based rom and allowing users to manage their launchers (whether it be system or user installed) should be helpful.
So this is what I came up with off hand but all I would get when I debugged it on my device in eclipse was a blank activity. "This code was wrote from memory, excuse any small errors. just to give you an idea what I did"
Code:
package com.Biotic.JBHomeManager;
public class HomeMain extends PreferenceFragment {
protected PackageManager getPackageManager() {
return getActivity().getPackageManager();
}
[user=439709]@override[/user]
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.home);
populateLaunchers();
}
private void populateLaunchers() {
Intent intent = new Intent(Intent.CATEGORY.HOME);
final PackageManager pm = getPackageManager();
List<ResolveInfo> rList = pm.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
final PreferenceScreen parent = getPreferenceScreen();
parent.setOrderingAsAdded(false);
for (ResolveInfo info : rList) {
Preference pref = new Preference(getActivity());
Intent prefIntent = new Intent(intent);
prefIntent.setComponent(new ComponentName(
info.activityInfo.packageName, info.activityInfo.name));
pref.setIntent(prefIntent);
CharSequence label = info.loadLabel(pm);
if (label == null) label = info.activityInfo.packageName;
pref.setTitle(label);
parent.addPreference(pref);
}
}
}
Code:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
android:title="Android Launchers">
</PreferenceScreen>
Any Ideas?
Hello!
First at all, I'm a beginner in android coding, I'm more a graphist with Photoshop as main tool.
A friend has made an app for my themes and is in holidays until september.
Beeing logical and understanding fast, with my friend Google we found the functions/codes I needed. Except one:
I have a horizontal scroll layout showing the apps needed to install the theme. Each app is showed in a linearlayout.
What I would like is make each linearlayout of apps clickable and make them show the app on the playstore when you click on it.
Thanks for reading
I assume you're using Textviews to add line by line the dependencies.. There is a property called autolink or very much like it that makes a link whenever it finds a url in the text...
But instead of Textviews in a linearlayout, why not use ListView? Then you can handle the click in the item to create an intent to open the browser with the url needed... it's a bit of more work but has a better esthetic than a bunch of TextViews... For instance, it makes it easier to use when in a ldpi device...
Sent from my LG-P350 using xda app-developers app
Sorry for the late.
I'm beginner in java coding so I don't undersand well what you mean dude.
In fact, what I have now is:
In res\layout\main.xml:
Code:
<HorizontalScrollView
android:id="@+id/layout5"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/layout3"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="8dp"
>
<LinearLayout
android:id="@+id/layout4"
android:background="#00000000"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</HorizontalScrollView>
In MainActivity.java:
Code:
boolean apexInstalled = appInstalledOrNot("com.anddoes.launcher");
RelativeLayout apexApp = (RelativeLayout) getLayoutInflater().inflate(R.layout.item, null);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams((int) (125 * scale + 0.5f),(int) (150 * scale + 0.5f));
ImageView apexI = (ImageView) apexApp.findViewById(R.id.appIcon);
apexI.setBackgroundResource(R.drawable.apexicon);
TextView apexT = (TextView) apexApp.findViewById(R.id.appText);
if(apexInstalled){
apexT.setText(R.string.installe);
apexT.setTextColor(Color.parseColor("#5a925d"));
}
else{
apexT.setText(R.string.nninstalle);
apexT.setTextColor(Color.parseColor("#de3747"));
}
apexT.setTypeface(font);
TextView apexTitle = (TextView) apexApp.findViewById(R.id.appTitle);
apexTitle.setText("Apex Launcher"); // \n == retour a la ligne
apexTitle.setTypeface(font);
apexApp.setBackgroundColor(Color.argb(190, 0, 0, 0));
listApp.addView(apexApp, params);
And I have many blocks like this one but with other apps, and I would like them to point on the playstore, what do I have to add?
Use a ListView with a custom Adapter: http://www.vogella.com/articles/AndroidListView/
Then add an OnItemClickedListener to the ListView.
In its onItemClick method you can use an Intent like this one:
Code:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
Thanks trying to help me, but I understand aproximatively the intent, but the listview etc, no..
I'm just trying to modify a bit an app somebody made for me using my logic to understand what I have to do. The problem is that I don't understand how to apply what you tell me :/

OK, then let's forget about the ListView if you just want to modify your existing app with as little effort as possible.
Try that in your Java code:
Code:
LinearLayout layout = findViewById(R.id.layout4);
layout.setClickable(true);
layout.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
}
});
(The word Override has to be written with a capital letter at the beginning. XDA does not allow that.)
But if I understand well that code, it will make a "link case" in the whole scroll layout no?
Or a link for each app?
If it's not possible to cut the horizontal scroll in little squares (links), is that possible to put a hyperlink on each imageview? So that click on the icon shows the store.

Yes, it does. I thought that the Linear layout was loaded as the layout for each app.
Ok. I think that the RelativeLayout in the MainActivity.java is your row, right?
If it is, that should work:
Code:
apexApp.setClickable(true);
apexApp.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getActivity().getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(getActivity(), "Google Play is not installed on the device.", Toast.LENGTH_LONG).show();
}
}
});
Yeah, each RelativeLayout is an app square. I'm not at home so I can't test it now, will later in the evening, thanks for your help!

Hello! I'm in front of a problem.
I wanted to face it alone, but I don't manage it..
I have had a problem with "uri", and after googleing, I've found that I had to import it.
But my problem is that I get that error:
Code:
The method getActivity() is undefined for the type new View.OnClickListener(){}
Any idea?

Ah, you're right. I'm sorry.
I copied the code from one of my fragments. Just delete the getActivity().
So it is:
Code:
apexApp.setClickable(true);
apexApp.setOnClickListener(new View.OnClickListener() {
[user=439709]@override[/user]
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + pkg); //Your package name here
if (getPackageManager().queryIntentActivities(intent, 0).size() > 0) {
startActivity(intent);
} else {
Toast.makeText(MainActivtiy.this, "Google Play is not installed on the device.", Toast.LENGTH_LONG).show(); //replace the MainActivity by your Activity
}
}
});
Works like a charm, thank you a lot Exactly what I wanted
If you need a graphist, I'm your man
PS: Is there a tool in Eclipse to make blocks of code lines? I mean, put them in blocs and then hide what you don't need.

Data Transferring Tool for All Android Powered Devices
Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream or a digitized analog signal) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal. READ MORE

There are several ways to transfer data between different type of devices. For Example, from SmartPhones to Another SmartDevices By Bluetooth that devices should connect together. Your App should handle these Processes. Beside using sensors to transfer data between devices there is In-App feature that allows Send/Receive data inside app. For Example Send Data from App on SmartPhone to client side on SmartWatch. In this way the application use system connection and it will handle data and not processes of detecting & connecting to peer(s).
In this thread I will write several Programming Tutorials for Data Transferring in Android.
Then I will use these tutorials to create a Tool for Send/Receive all types of Data to All Android Powered Devices.

### Let Start Coding ###
What you need is ability to create Hello World! project
Click to expand...
Click to collapse
You will learn How To Use
BroadcastReceiver, Custom Intent-Filet, Send/Receive Text to AndroidAuto,
Notification & CarExtender-Notification & etc.
Click to expand...
Click to collapse
. from Bottom to Top
First you need to Add XML file as meta-data for AndroidManifest to declare app as AndroidAuto Enabled app for system.
Under the .../res/ create xml folder. inside xml folder create xml resource file: automotive_app_desc.xml and Paste this
Code:
<?xml version="1.0" encoding="utf-8"?>
<automotiveApp>
<uses name="[B]notification[/B]"/>
<!-- [I]notification attribute shows your app is messaging app that only create androidAuto compatible notification[/I] -->
</automotiveApp>
then you need to link this file into manifest under <application />
Code:
<meta-data
android:name="com.google.android.gms.car.application"
android:resource="@xml/automotive_app_desc" /
>
After Installing App, It will notify Android Auto System.
There is 2 parts important for AndroidAuto Notification When TTS read content & when want to Reply Or send reply.
So to handle these parts we should define two BroadcastReceiver in manifest & creating classes.
Code:
<receiver android:name=".[B]MessageReadReceiver[/B]">
<intent-filter>
<action android:name="net.test.cartest.[B]ACTION_MESSAGE_READ[/B]"/>
</intent-filter>
</receiver>
<receiver android:name=".[B]ReplyReceiver[/B]" >
<intent-filter>
<action android:name="net.test.cartest.[B]ACTION_MESSAGE_REPLY[/B]" />
</intent-filter>
</receiver>
Then Create Classes & setup both of them as extends BroadcastReceiver.
Inside Activity class we need to create Android-Auto Compatible Notification.
For Messaging App It should be after users receive new message. I used it for Translator App > geTranslate. It means Notification will show translated text on Car Monitor Read result & use Reply action to reuse translator. However Translator App is not allowed for Android Auto.
Before creating notification we should define Intent Action to invoke BroadcastReceiver previously defined.
Code:
private Intent getMessageReadIntent(int conversationId) {
return new Intent().setAction(READ_ACTION).putExtra(CONVERSATION_ID, id); //[FONT=Impact](Check Source Code)[/FONT]
}
//Conversation ID must be unique.
private Intent getMessageReplyIntent(int conversationId) {
return new Intent().setAction(REPLY_ACTION).putExtra(CONVERSATION_ID, conversationId); //[FONT=Impact](Check Source Code)[/FONT]
}
Creating Notification itself is similar to phone notification But we need to extend it for Cars. to do this we need another component UnreadConversation.Builder
Code:
//This element will handle new how create new notifications
UnreadConversation.Builder unreadConversationBuilder = new UnreadConversation.Builder(sender)
.setLatestTimestamp(timestamp)
.setReadPendingIntent(readPendingIntent)
.setReplyAction(replyIntent, remoteInput);
unreadConversationBuilder.addMessage(message);
Then we should use it for CarExtender()
Code:
new CarExtender().setUnreadConversation(unreadConversationBuilder.build();
Here is Complete Function to define and create Android Auto Compatible Notification
Code:
private void sendNotificationToCar(int conversationId, String sender, String message, long timestamp) {
PendingIntent readPendingIntent = PendingIntent.getBroadcast(
getApplicationContext(),
conversationId,
getMessageReadIntent(conversationId),
PendingIntent.FLAG_UPDATE_CURRENT);
RemoteInput remoteInput = new RemoteInput.Builder(EXTRA_VOICE_REPLY)
.setLabel("Remote Inpute").build();
PendingIntent replyIntent = PendingIntent.getBroadcast(
getApplicationContext(),
conversationId,
getMessageReplyIntent(conversationId),
PendingIntent.FLAG_UPDATE_CURRENT);
UnreadConversation.Builder unreadConversationBuilder = new UnreadConversation.Builder(sender)
.setLatestTimestamp(timestamp)
.setReadPendingIntent(readPendingIntent)
.setReplyAction(replyIntent, remoteInput);
unreadConversationBuilder.addMessage(message);
NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(BitmapFactory.decodeResource(getApplicationContext().getResources(), R.drawable.ic_launcher))
.setContentText(message)
.setWhen(timestamp)
.setContentTitle(sender)
.setContentIntent(readPendingIntent)
.extend(new CarExtender().setUnreadConversation(unreadConversationBuilder.build()))
.setColor(Color.RED);
NotificationManagerCompat.from(this).notify(conversationId, builder.build());
}
Now you should handle Receivers. inside MessageReadReceiver you need to define actions to occur after TTS Engine read the content of notification & inside ReplyReceiver How reply actions work, in geTranslate I setup ReplayReceiver to invoke translator to translate what user spoke through car microphone.
Code:
public class [B]ReplyReceiver [/B]extends BroadcastReceiver { //[FONT=Impact](Check Source Code)[/FONT]
@Override
public void onReceive(Context context, Intent intent) {
if (MainActivity.REPLY_ACTION.equals(intent.getAction())) {
CharSequence reply = getMessageText(intent);
//Do What you want...
}
}
private CharSequence getMessageText(Intent intent) {
Bundle remoteInput = RemoteInput.getResultsFromIntent(intent);
if (remoteInput != null) {
return remoteInput.getCharSequence(MainActivity.EXTRA_VOICE_REPLY);
}
return null;
}
}
Up to Here you did what necessary for your app to support Android Auto. If you have access to real AndroidAuto Powered Vehicle Just Install you app and connect it to car & test your application.
But If you don't have access to androidAuto car you need to use simulator.
Code:
Install [COLOR=RoyalBlue][URL="http://forum.xda-developers.com/attachment.php?attachmentid=3444494&stc=1&d=1439998349"][B]CarNotification.APK[/B][/URL][/COLOR]

Install [B][URL="http://forum.xda-developers.com/attachment.php?attachmentid=3444491&stc=1&d=1439998135"]Simulator APK[/URL][/B] & Go to Setting > Notification Access > Enable Simulator
HOW TO Test Sample
Code:
[B]Open [/B]CarTest [B]Click [/B]on Text Then Click [B]Home [/B]& [B]Run Simulator [/B]> Wait [B]15Seconds [/B]to See Notification

### Let Start Coding ###There is just few different between AndroidApp on Phones & AndroidApp on Wearable.
The most important part is Optimizing User-Interface for AndroidWear & then keep in mind which API not available on AndroidWear. These APIs are not available on AndroidWear
android.webkit
android.print
android.app.backup
android.appwidget
android.hardware.usb
NOTE: Do Not set all processes of your app on SmartWatch Module. Cause there is smaller Battery, Memory& weaker Processor.
NOTE: You should use Android Studio to create AndroidWear App.
(However there is tricky way to use eclipse for androidWear But It s better to migrate to AndroidStudio ASAP.)
. from Bottom to Top /Watch Client
When you want to create New Android Application you can choose AndroidWear App Module then AndroidStudio will add necessary AndroidWear Components and Gradle Config automatically.
But you can add AndroidWear Module manually in your current project.
Code:
Go to
File > New > New Module > Select AndroidWear & Next to Finish.
Then you need to add required configuration in your Host Application to Link AndroidWear Module.
Open build.gradle (Module: name-of-project) of Host Application. & Add wearProject to Dependencies
Code:
dependencies{
...
wearApp project{':NAME-OF-PROJECT'}
...
}
Then Save & Sync.
Open AndroidManifest.xml & Add Uses-Features & Uses-Permissions
Code:
<uses-feature android:name="android.hardware.type.watch" />
NOTE: If you want to set new permission that is not in Phone Module you have to set on both Phone & Watch AndroidManifest. (Check Source Code)
There other components are same But for app that want to communicate between Phone & Watch add this meta-data under Application tag
Code:
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
There is different between phone layout design & watch. There is 3 layout.xml files for each Activity on SmartWatch.
main.xml Just Hold the View >>
<?xml version="1.0" encoding="utf-8"?>
<android.support.wearable.view.WatchViewStub
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/watch_view_stub"
android:layout_width="match_parent" android:layout_height="match_parent"
app:rectLayout="@layout/rectangle_main"
app:roundLayout="@layout/round_main"
tools:context=".WearActivity" tools:deviceIds="wear"></android.support.wearable.view.WatchViewStub>
Click to expand...
Click to collapse
rectangle_main.xml for Rectangle SmartWatch Display that All GUI components must Add here
round_main.xml for Round SmartWatch Display that All GUI components must Add here
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
[B] tools:context=".MainWear"[/B]
android:background="@android:color/white"
[B]tools:deviceIds="wear_square" [/B]>
[B]<!--
You should set context for activity that handle the components and Id to call on main view.
+
All other components like Buttons, TextViews, EditTextx should call here.
-->[/B]
</RelativeLayout>
Now I should add functionality to GUI components in Java.Classes.
To Communicate with Phone First of all I should Initiate GoogleApiClient to Get Node (Phone) connected to watch & get it ready for data communication
Code:
GoogleApiClient client = new GoogleApiClient.Builder(context).addApi(Wearable.API).build();
new Thread(new Runnable() {
@Override
public void run() {
client.blockingConnect(CONNECTION_TIME_OUT_MS, TimeUnit.MILLISECONDS);
NodeApi.GetConnectedNodesResult result = Wearable.NodeApi.getConnectedNodes(client).await();
List<Node> nodes = result.getNodes();
if (nodes.size() > 0) {
nodeId = nodes.get(0).getId();
}
client.disconnect();
}
}).start();
Then I should define WatchViewStub Listener & then other components inside it
Code:
final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
@Override
public void onLayoutInflated(WatchViewStub stub) {
//Here I should add all other functionalities
}
});
The proper Input Method on Android Wear is Voice Input. The main reason for this is small screens.
To Launch Voice Recognition Engine Call This Method
Code:
private static final int SPEECH_REQUEST_CODE = 0;
private void displaySpeechRecognizer() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
startActivityForResult(intent, SPEECH_REQUEST_CODE);
}
After This I need to get result from engine so i should define onActivityResult
Code:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == SPEECH_REQUEST_CODE && resultCode == RESULT_OK) {
//Here I should Handle Results
List<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
final String speech = results.get(0).toString();[B]
[COLOR=Red]//Here you can send this data to phone[/COLOR][/B]
}
To send data to app client on phone you can use Wearable.MessageApi.sendMessage()
Code:
if (nodeId != null) {
new Thread(new Runnable() {
@Override
public void run() {
client.blockingConnect(CONNECTION_TIME_OUT_MS, TimeUnit.MILLISECONDS);
Wearable.MessageApi.sendMessage(client, nodeId, MESSAGE, null);
client.disconnect();
}
}).start();
}
. from Bottom to Top /Phone Client
On the Phone Side Open AndroidManifest.xml & Add Service to Handle Received data from Watch with specific <intent-filter/>
<service android:name=".WearReceiver" >
<intent-filter>
<action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
</intent-filter>
</service>
Then Create Class extends of WearableListenerService to get data and add all operation we want.
Code:
public class WearReceiver extends WearableListenerService {
@Override
public void onMessageReceived(MessageEvent messageEvent) {
String getWear = messageEvent.getPath(); [COLOR=Red][B]//Text from Watch[/B][/COLOR]
System.out.println("DEVICE >> " + messageEvent.getPath());
}
}
Done! But You Always you need to Test your App.
If you create Signed APK you can Install it on Phone & It will install on AndroidWear automatically.
NOTE: buildToolsVersion must be same on both Phone & Watch Module.
If you have AndroidWear Device Just Connect it & install it like normal app on phones. It same if you run Emulator But to use emulator you need to do few steps before
First go to Android Virtual Device (AVD) Manager & Create Emulator for both Square & Round Display Watches.
Install AndroidWear App from Google Play Store
In AndroidWear App select Emulator
Open Terminal & Go to ADB directory & type this command
Code:
adb -d forward tcp:5601 tcp:5601

Android Wear [Phone-To-Watch][Data Transferring]
Android Wear is a version of Google's Android operating system designed for smartwatches and other wearables.
By pairing with mobile phones running Android version 4.3+, Android Wear integrates Google Now technology and mobile notifications into a smartwatch form factor. It also adds the ability to download applications from the Google Play Store.
Android Wear supports both Bluetooth and Wi-Fi connectivity, as well as a range of features and applications. Watch face styles include round, square and rectangular. Released devices include Motorola Moto 360,the LG G Watch, and the Samsung Gear Live.Hardware manufacturing partners include ASUS, Broadcom, Fossil, HTC, Intel, LG, MediaTek, Imagination Technologies, Motorola, Qualcomm, and Samsung.
In the first six months of availability, Canalys estimates that over 720,000 Android Wear smartwatches were shipped.As of 15 May 2015, Android Wear had between one and five million application installations.

### Let Start Coding ###
There is just few different between AndroidApp on Phones & AndroidApp on Wearable.
The most important part is Optimizing User-Interface for AndroidWear & then keep in mind which API not available on AndroidWear. These APIs are not available on AndroidWear
android.webkit
android.print
android.app.backup
android.appwidget
android.hardware.usb
NOTE: Do Not set all processes of your app on SmartWatch Module. Cause there is smaller Battery, Memory& weaker Processor.
NOTE: You should use Android Studio to create AndroidWear App.
(However there is tricky way to use eclipse for androidWear But It s better to migrate to AndroidStudio ASAP.)
WHY Should You Transfer Data to AndroidWear Client?
- Beside using Wear Notification Extender to deliver info to SmartWatch you can transfer data to Watch Client of your App directly. In this way you will be able to do some modification on data before displaying to users on watches OR sharing data securely inside your app.
from Bottom to Top /Watch Client
When you want to create New Android Application you can choose AndroidWear App Module then AndroidStudio will add necessary AndroidWear Components and Gradle Config automatically.
But you can add AndroidWear Module manually in your current project.
Code:
Go to
File > New > New Module > Select AndroidWear & Next to Finish.
Then you need to add required configuration in your Host Application to Link AndroidWear Module.
Open build.gradle (Module: name-of-project) of Host Application. & Add wearProject to Dependencies
Code:
dependencies{
...
wearApp project{':NAME-OF-PROJECT'}
...
}
Then Save & Sync.
Open AndroidManifest.xml & Add Uses-Features & Uses-Permissions
Code:
<uses-feature android:name="android.hardware.type.watch" />
NOTE: If you want to set new permission that is not in Phone Module you have to set on both Phone & Watch AndroidManifest. (Check Source Code)
There other components are same But for app that want to communicate between Phone & Watch add this meta-data under Application tag
Code:
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
***AndroidWear GUI Guide
There is different between phone layout design & watch. There is 3 layout.xml files for each Activity on SmartWatch.
main.xml Just Hold the View >>
Code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.wearable.view.WatchViewStub
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/watch_view_stub"
android:layout_width="match_parent" android:layout_height="match_parent"
app:rectLayout="@layout/rectangle_main"
app:roundLayout="@layout/round_main"
tools:context=".WearActivity" tools:deviceIds="wear"></android.support.wearable.view.WatchViewStub>
rectangle_main.xml for Rectangle SmartWatch Display that All GUI components must Add here
round_main.xml for Round SmartWatch Display that All GUI components must Add here
Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainWear"
android:background="@android:color/white"
tools:deviceIds="wear_square" >
<!--
You should set context for activity that handle the components and Id to call on main view.
+
All other components like Buttons, TextViews, EditTextx should call here.
-->
</RelativeLayout>
You should set context for activity that handle the components and Id to call on main view.
+
All other components like Buttons, TextViews, EditTextx should call here.
***
I should define an Activity & Service extends WearableListenerService for Wear Module.
The Service must have intent filter to Bind it.
Code:
<action android:name="com.google.android.gms.wearable.BIND_LISTENER" />
Inside the listener you can handle the Received Data But in this example I just get the Intent-Filter-Action & launch the activity by getting the data path
Code:
if(messageEvent.getPath().equalsIgnoreCase("String Intent Filter Action")){
//Start Activity
}
In this example I used simple text as data so to get text data I can setup data like this
Code:
@Override
public void onMessageReceived(MessageEvent messageEvent) {
String receivedTextFromPhoneClient = messageEvent.getData().toString();
}
In case you want to launch an activity you have to setup some implementation to receive data
Code:
public class MainActivity extends Activity implements MessageApi.MessageListener, GoogleApiClient.ConnectionCallbacks{}
& put all necessary override functions
Code:
public void onMessageReceived( final MessageEvent messageEvent ) {}
public void onConnected(Bundle bundle) {}
public void onConnectionSuspended(int i) {}
Inside activity I must initialize the GoogleApiClient to connect to peer and get data
Code:
GoogleApiClient mApiClient = new GoogleApiClient.Builder( this )
.addApi( Wearable.API )
.addConnectionCallbacks( this )
.build();
if( mApiClient != null && !( mApiClient.isConnected() || mApiClient.isConnecting() ) )
mApiClient.connect();
Make Sure to release Listener when quitting the activity
Code:
@Override
protected void onStop() {
if ( mApiClient != null ) {
Wearable.MessageApi.removeListener( mApiClient, this );
if ( mApiClient.isConnected() ) {
mApiClient.disconnect();
}
}
super.onStop();
}
To get Received Data from peer you should do it inside onMessageReceived function //(Check Source Code)
Code:
@Override
public void onMessageReceived( final MessageEvent messageEvent ) {
runOnUiThread( new Runnable() {
@Override
public void run() {
if( messageEvent.getPath().equalsIgnoreCase( WEAR_MESSAGE_PATH ) ) {
mAdapter.add(new String([B]messageEvent.getData()[/B])); //Data from Phone
mAdapter.notifyDataSetChanged();
}
}
});
}
But Where is Data come from?
Let Code the Phone Client to Send Data to SmartWatch.
from Bottom to Top /Phone Client
First of All Don't forget to add <meta-data/> to AndroidManifest.xml under <Application/>
Inside Activity Setup Views as you prefer to get user input & send it to watch.
In this example I set EditText & Button to get input and send data.
Like Watch Client First initialize GoogleApiClient so that I need to add implementation to GoogleApiClient.ConnectionCallbacks & its override functions.
Just Call these three functions at onCreate session.
Code:
private void initGoogleApiClient() {
mApiClient = new GoogleApiClient.Builder( this )
.addApi( Wearable.API )
.build();
mApiClient.connect();
}
Code:
private void init() {
mSendButton.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View view) {
String text = mEditText.getText().toString();
if (!TextUtils.isEmpty(text)) {
sendMessage(WEAR_MESSAGE_PATH, text);
}
}
});
}
& final Send function to Watch Client
Code:
private void [COLOR=Red][B]sendMessage[/B][/COLOR]( final String path, final String text ) {
new Thread( new Runnable() {
@Override
public void run() {
NodeApi.GetConnectedNodesResult nodes = Wearable.NodeApi.getConnectedNodes( mApiClient ).await();
for(Node node : nodes.getNodes()) {
MessageApi.SendMessageResult result = Wearable.MessageApi.sendMessage(
mApiClient, node.getId(), path, text.getBytes() ).await();
}
runOnUiThread( new Runnable() {
@Override
public void run() {
mEditText.setText( "" );
}
});
}
}).start();
}
NOTE: There is two parameters that the values & names must be same inside both Phone & Watch Client
The String of Intent-Filter-Action & Message-Path
Code:
private static final String ACTION = "/start_activity";
private static final String WEAR_MESSAGE_PATH = "/message";
NOTE: buildToolsVersion must be same on both Phone & Watch Module.
If you have AndroidWear Device Just Connect it & install it like normal app on phones. It same if you run Emulator But to use emulator you need to do few steps before
First go to Android Virtual Device (AVD) Manager & Create Emulator for both Square & Round Display Watches.
Install AndroidWear App from Google Play Store

Android TV [Data Transferring]
Android offers a rich user experience that's optimized for apps running on large screen devices, such as high-definition televisions. Apps on TV offer new opportunities to delight your users from the comfort of their couch...
Android TV apps use the same structure as those for phones and tablets. This similarity means you can modify your existing apps to also run on TV devices or create new apps based on what you already know about building apps for Android.
Click to expand...
Click to collapse
### Let Start Coding ###For TV Apps you must just Focus on GUI. You can use all your codes for Phone App but for Bigger Layout Components.
Also There might be some limitation for Hardware on TV.
This is list of Un-Supported Hardware feature on Android TV
Code:
Touchscreen - android.hardware.touchscreen
Touchscreen emulator - android.hardware.faketouch
Telephony - android.hardware.telephony
Camera - android.hardware.camera
Near Field Communications (NFC) - android.hardware.nfc
GPS - android.hardware.location.gps
Microphone - android.hardware.microphone
Sensors - android.hardware.sensor
. from Bottom to Top
In AndroidManifest.xml you must declare <activity /> for TV class with different Category for Intent Filter & Theme.
Code:
<activity
android:name="com.example.android.TvActivity"
android:label="@string/app_name"
android:theme="@style/[COLOR=Red][B]Theme.Leanback[/B][/COLOR]">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="[COLOR=Red][B]android.intent.category.LEANBACK_LAUNCHER[/B][/COLOR]" />
</intent-filter>
</activity>
& Under <manifest/> declare TV Support Library usage.
Code:
<uses-feature android:name="android.software.leanback"
android:required="false" />
Before/After this declaration you need to configue Hardware feature requirement. For Example:
Code:
...
<uses-feature android:name="android.hardware.touchscreen"
android:required="false" />
...
Also When you want to Add TV support you should design new graphical element as banner for LeanBackLauncher
Under <application /> add
Code:
...
android:banner="@drawable/banner"
...
After this Focus on GUI & Test App. You need to define bigger graphical component that user can see from longer distance compare when look at phone or tablet.
GUI Guide for Android TV App
NOTE: Creating TV Module Using Android Studio Will Add Everything you need for TV App automatically.

HOW TO Create Cloud Base App Using Google Cloud
HOW TO Create Cloud Base App Using Custom Server (Coming Soon)
Bluetooth [Data Transferring]
The Android platform includes support for the Bluetooth network stack, which allows a device to wirelessly exchange data with other Bluetooth devices. The application framework provides access to the Bluetooth functionality through the Android Bluetooth APIs. These APIs let applications wirelessly connect to other Bluetooth devices, enabling point-to-point and multipoint wireless features.
Using the Bluetooth APIs, an Android application can perform the following:
Scan for other Bluetooth devices
Query the local Bluetooth adapter for paired Bluetooth devices
Establish RFCOMM channels
Connect to other devices through service discovery
Transfer data to and from other devices
Manage multiple connections
Click to expand...

Using Bluetooth can be so Helpful in many cases.
Send to & Receive Data from many devices. SmartPhone,any Bluetooth stations & etc.
But If you want to have control of what happen with data sharing with Bluetooth you must learn How to Transfer Data through Bluetooth Socket. For many simple cases Android Provided Intent base Bluetooth Sharing But It is not enough. So I will write here how to use Bluetooth for both situation.
### Let Start Coding ###
Additionally in this tutorial you will learn How to access Files & Converting to byteArray.
. from Bottom to Top /Watch Client
Start New Project & Leave everything to default.
After Sync Gradle Open AndroidManifest.xml to Add Permissions.
Code:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/> //to Enable/Disable Bluetooth
<uses-permission android:name="android.permission.BLUETOOTH"/>
Also for Android API 23+ you should ask for Runtime Permission too.
Code:
if(Build.VERSION.SDK_INT >= 23) {
String[] Permissions = {Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.BLUETOOTH, Manifest.permission.BLUETOOTH_ADMIN};
requestPermissions(Permissions, 10296);
}
Then Open your Bluetooth Activity and Add this Code.
Here is Simple Way to Share File using Bluetooth. Like other Intent sharing Just Invoke its intent-filter
Code:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_SEND);
intent.setType("text/plain");//define type
File f = new File(Environment.getExternalStorageDirectory(), "DIR_TO_FILE");
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(f));
startActivity(intent);
Little More Complex Way is to use Bluetooth Socket.
It finds List of All Paired Bluetooth Devices.
Code:
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
// Loop through paired devices
for (BluetoothDevice device : pairedDevices) {
// Add the name and address to an array adapter to show in a ListView
System.out.println(device.getName() + "\n" + device.getAddress() + "\n\n");
}
}
to connect to another device you need to have its MacAddress.
Code:
String macAddress = new BluetoothDevice().getAddress();
BluetoothDevice [COLOR=Red][B]device [/B][/COLOR]= mBluetoothAdapter.getRemoteDevice(macAddress);
After this you should invoke instance of Socket to start Connection.
NOTE: Nothing should define on Main View. In other hand you have to use Thread(); for background Process.
Code:
Connecting [B]connectThread [/B]= new Connecting([COLOR=Red][B]device [/B][/COLOR]/*Pass Device Information to Thread()*/);
[B]connectThread[/B].start();
Code:
private class Connecting extends Thread {
private final BluetoothSocket [COLOR=Red]bluetoothSocket [/COLOR];
private final BluetoothDevice bluetoothDevice ;
private String mSocketType;
public ConnectThread(BluetoothDevice device) {
bluetoothDevice = device;
[B]BluetoothSocket [/B][COLOR=Red]tmp [/COLOR]= null;
try {
[COLOR=Red]tmp [/COLOR]= device.createRfcommSocketToServiceRecord(MY_UUID_SECURE);
catch (IOException e) {e.printStackTrace();}
[COLOR=Red]bluetoothSocket [/COLOR]= tmp;
}
public void run() {
BluetoothAdapter.getDefaultAdapter().cancelDiscovery();
try {
[COLOR=Red][B]bluetoothSocket.connect();[/B][/COLOR]
} catch (IOException e) {
try {
[COLOR=Red]bluetoothSocket[/COLOR].close();
} catch (IOException e2) {e2.printStackTrace();break;}
return;
}
[COLOR=RoyalBlue][B]//Handle Actions After Connecting.
//Ask to Write & Read Socket Data
// SO HERE you should start another Thread(); to handle [COLOR=Red]Write/Read[/COLOR] Process
[/B][/COLOR][COLOR=RoyalBlue][B][COLOR=Red][COLOR=SeaGreen]globalConnectedThread [/COLOR]= new ConnectedThread(socket, socketType).start();[/COLOR][/B][/COLOR][COLOR=RoyalBlue][COLOR=Black]//pass the socket Information[/COLOR][/COLOR]}
public void cancel() {
try {
bluetoothSocket.close();
} catch (IOException e) {e.printStackTrace();}
}
}
So Check this snippet Carefully and Read Comments
Code:
private class ConnectedThread extends Thread {
private final BluetoothSocket [B]mmSocket[/B];
private final InputStream [COLOR=Red][B]mmInStream[/B][/COLOR];
private final OutputStream [COLOR=Red][B]mmOutStream[/B][/COLOR];
public ConnectedThread(BluetoothSocket socket, String socketType) {
[B]mmSocket [/B]= socket;[COLOR=Red] //you call it on Connecting thread after successful connecting process So pass the socket to this thread[/COLOR]
InputStream [B]tmpIn [/B]= null;
OutputStream [B]tmpOut [/B]= null;
// Get the BluetoothSocket input and output streams
try {
tmpIn = [B]socket[/B].getInputStream();
tmpOut = [B]socket[/B].getOutputStream();
} catch (IOException e) {}
[COLOR=Red][B]mmInStream [/B][/COLOR]= tmpIn;
[COLOR=Red][B]mmOutStream [/B][/COLOR]= tmpOut;
}
public void run() {
byte[] buffer = new byte[1024];
int bytes;
// Keep listening to the InputStream while connected
while (/*define indicator to check if sockets are connected you can do it by using a integer or boolean var*/) {
try {
// Read from the InputStream in loop until connection not lost
bytes = [B]mmInStream[/B].[B][COLOR=Red]read([COLOR=Black]buffer[/COLOR])[/COLOR][/B];
// Send the obtained bytes to the UI Activity OR SAVE Data
//so we call a function save data to file.
saveFile("name_of_file");
//pass read data to views
} catch (IOException e) {
// Start the service over to restart listening mode
this.start();
break;
}
}
}
public void [B]write[/B](byte[] buffer) {//next snippet will show how to use it.
try {
[B]mmOutStream[/B].[COLOR=Red][B]write([COLOR=Black]buffer[/COLOR])[/B][/COLOR];
// Share the sent message back to the UI Activity
} catch (IOException e) {}
}
public void cancel() {
try {
[B]mmSocket[/B].close();
} catch (IOException e) {}
}
}
To Write to Socket from File you must read content of File (that is why we got permission for reading sdcard) and convert it to array of byte and pass to socket. So define ConnectedThread and call write(byte[]) function
Code:
ConnectedThread connectedThread = [COLOR=SeaGreen][B]globalConnectedThread[/B][/COLOR];//this is the value defined after socket connected.
byte[] sendData = [B]readFile[/B]("file_name_on_sdcard").getBytes();//Check out next snippet for readFile Function
[B]connectedThread.[COLOR=Red]write[/COLOR](sendData);[/B]
This Function to read simple text file from sdcard
Code:
public String [B]readFile[/B](String fileName){
String temp = "";
File G = new File(Environment.getExternalStorageDirectory(), fileName);
if(!G.exists()){
System.out.println(fileName + " NOT FOUND");
}
else{
try{
BufferedReader br = new BufferedReader(new FileReader(G));
int c;
temp = "";
while((c = br.read()) != -1){
temp = temp + Character.toString((char)c);
}
}
catch(Exception e){e.printStackTrace();}
}
return temp;//content of file
}
In other hand you must Handle read data on socket and save it.
Code:
public void [B]saveFile[/B](String fileName, String content){
File G = new File(Environment.getExternalStorageDirectory(), fileName);
try {
FileOutputStream fOut = new FileOutputStream(G);
fOut.write((content).getBytes());
fOut.flush();
fOut.close();
}
catch (IOException e) {
e.printStackTrace();
}
}
NOTE: As you may realized this tutorial contained functionality for both Client & Server Side of Bluetooth connection.
So when compiled your test app, install it on 2 devices & pair them.

WiFi Direct | Android Beam [Client|Server][Data Transferring]
Wi-Fi peer-to-peer (P2P) allows Android 4.0 (API level 14) or later devices with the appropriate hardware to connect directly to each other via Wi-Fi without an intermediate access point (Android's Wi-Fi P2P framework complies with the Wi-Fi Alliance's Wi-Fi Direct™ certification program). Using these APIs, you can discover and connect to other devices when each device supports Wi-Fi P2P, then communicate over a speedy connection across distances much longer than a Bluetooth connection. This is useful for applications that share data among users, such as a multiplayer game or a photo sharing application.
The Wi-Fi P2P APIs consist of the following main parts:
Methods that allow you to discover, request, and connect to peers are defined in the WifiP2pManager class.
Listeners that allow you to be notified of the success or failure of WifiP2pManager method calls. When calling WifiP2pManager methods, each method can receive a specific listener passed in as a parameter.
Intents that notify you of specific events detected by the Wi-Fi P2P framework, such as a dropped connection or a newly discovered peer.
You often use these three main components of the APIs together. For example, you can provide a WifiP2pManager.ActionListener to a call to discoverPeers(), so that you can be notified with the ActionListener.onSuccess() and ActionListener.onFailure() methods. A WIFI_P2P_PEERS_CHANGED_ACTION intent is also broadcast if the discoverPeers() method discovers that the peers list has changed.

WiFi Direct can be used as main part of data transferring Or you can use it after initial connection with NFC. Android System uses Wifi Direct & Bluetooth to transfer a large amount of data after NFC connection.
### Let Start Coding ###
Wifi Direct has 2 part: Client & Server.
Your app must have contains both parts to be able to transfer data via Wifi Direct.
Both sides need 3 classes: Activity - BroadcastReceiver - Server.
Client Side needs more work to do, so I begin with Wifi Direct - Client

Note: Developing for Socket Communication needs vivid vision to understand how it works. Then use all components correctly step by step. So I will explain more about each section. Read Carefully.

I don't enter to layout.xml & won't talk about GUI/UX in this tutorial. So you can design your layout and put codes and expanding functionality of your apps.
Click to expand...
Click to collapse
So create 3 classes & register them to Manifest.
ClientActivity
ClientReceiver
ClientService
Open ClientActivity. First, I need a file for sending over Wifi. You can use a file inside your app as assets, from SdCard Or create general FilePicker.
I set an image from /sdcard/Download/ directory. @onCreate(Bundle)
Code:
File [B][COLOR="Red"]fileToSend [/COLOR][/B]= new File(Environment.getExternalStorageDirectory().getPath() + "/Download/shuttle.jpg");
Now, You should initialize instance WifiP2pManager @onCreate(Bundle)
Code:
WifiP2pManager wifiManager = (WifiP2pManager) getSystemService(Context.WIFI_P2P_SERVICE);
Channel wifichannel = wifiManager.initialize(this, getMainLooper(), null);
Then, You should Register a BroadcastReceiver with proper IntentFilter Actions.
Code:
IntentFilter wifiClientReceiverIntentFilter = new IntentFilter();
wifiClientReceiverIntentFilter.addAction(WifiP2pManager.WIFI_P2P_STATE_CHANGED_ACTION);
wifiClientReceiverIntentFilter.addAction(WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION);
wifiClientReceiverIntentFilter.addAction(WifiP2pManager.WIFI_P2P_CONNECTION_CHANGED_ACTION);
wifiClientReceiverIntentFilter.addAction(WifiP2pManager.WIFI_P2P_THIS_DEVICE_CHANGED_ACTION);
registerReceiver([B]ClientReceiver[/B]/*I will edit receiver later*/, wifiClientReceiverIntentFilter);
After this, You should invoke Peer Descovery. Also, It makes device discoverable
Code:
wifiManager.discoverPeers(wifichannel, new WifiP2pManager.ActionListener() {
public void onSuccess() {
//done
}
public void onFailure(int i) {
}});
And wait in ClientReceiver to setup peers. But, It is better to create a function in ClientActivity & pass instance of activity to receiver to access the functions. Check Sample Codes
Code:
public void [B][COLOR="red"]listOfPeers[/COLOR][/B](final WifiP2pDeviceList peers) {
ListView peerView = (ListView) findViewById(R.id.peers_listview);
ArrayList<String> peersStringArrayList = new ArrayList<String>();
for(WifiP2pDevice wd : peers.getDeviceList()) {
peersStringArrayList.add(wd.deviceName);
}
peerView.setClickable(true);
ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, peersStringArrayList.toArray());
peerView.setAdapter(arrayAdapter);
peerView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int arg2,long arg3) {
TextView tv = (TextView) view;
WifiP2pDevice device = null;
for(WifiP2pDevice wd : peers.getDeviceList()) {
if(wd.deviceName.equals(tv.getText()))
device = wd;
}
[B][COLOR="red"]if(device != null) {
/*Connect to first Device*/
targetDevice = device;
WifiP2pConfig config = new WifiP2pConfig();
config.deviceAddress = device.deviceAddress;
wifiManager.connect(wifichannel, config, new WifiP2pManager.ActionListener() {
public void onSuccess() {}
public void onFailure(int reason) {}
});
}[/COLOR][/B]
}});}
Open ClientReceiver to request list of peers when proper action occurs Check Sample Codes
Code:
if (WifiP2pManager.WIFI_P2P_PEERS_CHANGED_ACTION.equals(action)) {
manager.requestPeers(channel, new WifiP2pManager.PeerListListener() {
public void onPeersAvailable(WifiP2pDeviceList peers) {
[COLOR="DarkOrchid"]activity[/COLOR].[B][COLOR="red"]listPeers[/COLOR][/B](peers);
}});
}
I set codes for connecting to a peer. But rewrite it here to consider it here in details
Code:
public void connectToPeer(final WifiP2pDevice wifiPeer){
targetDevice = wifiPeer;
/*[COLOR="Red"]Wi-Fi P2p configuration for setting up a connection[/COLOR]*/
WifiP2pConfig config = new WifiP2pConfig();
config.deviceAddress = wifiPeer.deviceAddress;
wifiManager.connect([COLOR="red"]wifichannel[/COLOR], [COLOR="red"]config[/COLOR], new WifiP2pManager.ActionListener() {
public void onSuccess() {}
public void onFailure(int reason) {}
}); }
Now, It is time to perform sending actions in ClientService and for this you should pass required info to service to open socket and write on it...
Port Number
WifiP2pInfo
File
So, After registering a receiver to get information when proper actions occur & getting list of peers, connection stablished & Now you can write data to Socket.OutputStream
Code:
Intent clientServiceIntent = new Intent(this, ClientService.class);
clientServiceIntent.putExtra("fileToSend", [B][COLOR="red"]fileToSend[/COLOR][/B]);
clientServiceIntent.putExtra("port", Integer.valueOf([B][COLOR="red"]port[/COLOR][/B]/*set what you want*/));
clientServiceIntent.putExtra("wifiInfo", [B][COLOR="Red"]wifiInfo[/COLOR][/B]);
startService(clientServiceIntent);
Then Open ClientService & set to get passed data
Code:
port = (Integer) intent.getExtras().get("port");
fileToSend = (File) intent.getExtras().get("fileToSend");
clientResult = (ResultReceiver) intent.getExtras().get("clientResult");
wifiInfo = (WifiP2pInfo) intent.getExtras().get("wifiInfo");
Now you can define socket and try to write data.
Before that you need proper address of target device
Code:
InetAddress [COLOR="RoyalBlue"]targetIP [/COLOR]= [B][COLOR="red"]wifiInfo[/COLOR][/B].groupOwnerAddress;
Now you can open socket and writing data Check Sample Codes
Code:
try {
Socket clientSocket = new Socket([B][COLOR="royalblue"]targetIP[/COLOR][/B], [B][COLOR="Red"]port[/COLOR][/B]);
OutputStream os = clientSocket.getOutputStream();
PrintWriter pw = new PrintWriter(os);
InputStream is = clientSocket.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
byte[] buffer = new byte[4096];
FileInputStream fis = new FileInputStream(fileToSend);
BufferedInputStream bis = new BufferedInputStream(fis);
[B][COLOR="RoyalBlue"]while(true) {
int bytesRead = bis.read(buffer, 0, buffer.length);
if(bytesRead == -1) {break;}
[SIZE="4"]os.write(buffer,0, bytesRead);[/SIZE]
os.flush();
}[/COLOR][/B]
fis.close();
bis.close();
br.close();
isr.close();
is.close();
pw.close();
os.close();
clientSocket.close();
}
catch(Exception e) {e.printStackTrace();}
. Wifi Direct | Server
First, Register a BroadcastReceiver with Same IntentFilter Actions to get notification of connection information & specify a Path to store receiving data
Code:
/*this should be a directory*/
File downloadTarget = new File(Environment.getExternalStorageDirectory().getPath() + "/Download/");
Then start service and pass required data and prepare it to listen on socket with same port
Path to Store Data
Port Number
Code:
Intent serverServiceIntent = new Intent(this, ServerService.class);
serverServiceIntent.putExtra("saveLocation", downloadTarget);
serverServiceIntent.putExtra("port", Integer.valueOf(port));
startService(serverServiceIntent);
Now you can accept socket from specified port on server side and listen to read data Check Sample Codes
Code:
try {
[B][COLOR="royalblue"]ServerSocket welcomeSocket = new ServerSocket(port);
Socket socket = welcomeSocket.accept();[/COLOR][/B]
InputStream is = socket.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
OutputStream os = socket.getOutputStream();
PrintWriter pw = new PrintWriter(os);
String inputData = "";
String savedAs = "WifiDirectDemo." + System.currentTimeMillis();
File file = new File(saveLocation, savedAs);
byte[] buffer = new byte[4096];
int bytesRead;
FileOutputStream fos = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fos);
/*[B][COLOR="Red"]Read data from Socket & Write it to a file[/COLOR][/B]*/
while(true)
{
bytesRead = is.read(buffer, 0, buffer.length);
if(bytesRead == -1){break;}
bos.write(buffer, 0, bytesRead);
bos.flush();
}
bos.close();
socket.close();
}
catch(Exception e) {e.printStackTrace();}

NFC [Data Transferring][Send File][Write Data to NFC Tag][Read Data from NFC Tag]
Android allows you to transfer large files between devices using the Android Beam file transfer feature. This feature has a simple API and allows users to start the transfer process by simply touching devices. In response, Android Beam file transfer automatically copies files from one device to the other and notifies the user when it's finished.

NFC (Near Field Communication) is the best way to transfer important data.
The data can be simple URI of File (Image & etc) from your SdCard, Info of Music Track Or Bank Account Information for transferring money.
And I think, It will be inside all electronic devices in near future.

Different Usage of NFC | How Secure is NFC
What is NFC Tag
You will learn How to...
I. Transfer Simple File to another Device by NFC
II. Write Data to NFC Tag
III. Read Data from NFC Tag
Click to expand...
Click to collapse
### Let Start Coding ###
. Send a File
Create a Project on Android Studio. Set minSdk to API 16 & Open AndroidManifest.xml to add required permissions and features
Code:
<uses-permission android:name="android.permission.NFC" />
<uses-permission android:name="android.permission.BIND_NFC_SERVICE"/>
<uses-feature android:name="android.hardware.nfc" android:required="true" />
Open layout.xml and add <Button /> & <ImageView/> whereever you like.
Then Open Activity.Java to initialize NfcAdapter & Set URI of Data.
For example, I used a simple ImagePicker to get URI of Image File and set it for NFC transferring.
Code:
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 143);
/*then call [COLOR="Red"]onActivityResult[/COLOR] to get URI of file*/
}
});
After clicking on ImagePicker Button, it will redirect you to select an image. Then you will back to the app and get information of the picked image. Also, you can define Uri imageUri; to store the data and use is later.
Code:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case 143:
if(resultCode == RESULT_OK){
try {
/*this is what app need to set for nfc*/
/*you can also set it to nfcAdapter here*/
[B][COLOR="red"]Uri imageUri[/COLOR];[/B] = imageReturnedIntent.getData();
final InputStream imageStream = getContentResolver().openInputStream(imageUri);
final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
imageView.setImageBitmap(selectedImage);
}
catch (FileNotFoundException e) {e.printStackTrace();}
}}}
You can also set the URI to nfcAdapter here. I set when image show to user and He/She get what exactly going on and then by clicking on ImageView confirm & set it to NfcAdapter.
Code:
imageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
/*NfcAdapter init*/
[B]nfcAdapter = NfcAdapter.getDefaultAdapter(getApplicationContext());[/B]
// Check whether NFC is enabled on device
if(!nfcAdapter.[B]isEnabled[/B]()){
// NFC is disabled, show the settings to enable NFC
Toast.makeText(getApplicationContext(), "Turn On NFC", Toast.LENGTH_SHORT).show();
startActivity(new Intent(Settings.ACTION_NFC_SETTINGS));
}
// Check whether Android Beam feature is enabled on device
else if(!nfcAdapter.[B]isNdefPushEnabled[/B]()) {
// Android Beam is disabled, show the settings to enable Android Beam
Toast.makeText(getApplicationContext(), "Enable Android Beam", Toast.LENGTH_SHORT).show();
startActivity(new Intent(Settings.ACTION_NFCSHARING_SETTINGS));
}
else {
// NFC and Android Beam both are enabled
if (imageUri != null) {
/*URI if File set to NfcAdapter for transfering*/
nfcAdapter.setBeamPushUris(new Uri[]{[B][COLOR="red"]Uri imageUri[/COLOR];[/B]}, MainActivity.this);
}
else {
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 143);
}
}}});
Now, users should touch their devices and wait for files.
Check out this line.
Code:
nfcAdapter.setBeamPushUris(new Uri[]{[B][COLOR="red"]Uri imageUri[/COLOR];[/B]}, MainActivity.this);
You can call it whenever you want & as you can see, there can be several URI of files.
. Write Data to NFC Tag
There is no additional permissions & features for this. Check If your NFC Tags are Writable.
Initialize NfcAdapter @oncreate(Bundle)
Code:
NfcAdapter = NfcAdapter.getDefaultAdapter(getApplicationContext());
Then add <Intent-filter/> to detect NFC connections. I set filters as a PendingIntent [COLOR="RoyalBlue" [user=815433]@onres[/user]ume()[/COLOR][/B]
[CODE]IntentFilter ACTION_TAG_DISCOVERED = new IntentFilter(NfcAdapter.ACTION_TAG_DISCOVERED);
IntentFilter ACTION_NDEF_DISCOVERED = new IntentFilter(NfcAdapter.ACTION_NDEF_DISCOVERED);
IntentFilter ACTION_TECH_DISCOVERED = new IntentFilter(NfcAdapter.ACTION_TECH_DISCOVERED);
IntentFilter[] nfcIntentFilter = new IntentFilter[]{ACTION_TAG_DISCOVERED, ACTION_NDEF_DISCOVERED, ACTION_TECH_DISCOVERED};
PendingIntent pendingIntent = PendingIntent.
getActivity(this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);
if(nfcAdapter != null) {
[B]nfcAdapter[/B].[COLOR="red"]enableForegroundDispatch[/COLOR](this, pendingIntent, nfcIntentFilter, null);
/*enableForegroundDispatch; This will give give priority to the foreground activity when dispatching a discovered Tag to an application.*/
}
[/CODE]
Now, you can detect when NfcTag touch your device. So you need to initialize NFC.Tag instance & store is in Tag tag;
Code:
@Override
protected void onNewIntent(Intent intent) {
[B][COLOR="red"]tag [/COLOR][/B]= intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
}
I use ImagePicker Button to perform writing action on press and hold.
I will write String of Image URI to NFC tag.
Code:
picker.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
if([B][COLOR="red"]tag [/COLOR][/B]!= null) {
Ndef ndef = Ndef.get([B][COLOR="red"]tag[/COLOR][/B]);
if (ndef != null) {
try {
ndef.connect();
NdefRecord mimeRecord = NdefRecord.createMime("text/plain", [B][COLOR="red"]imageUriString[/COLOR][/B].getBytes());
ndef.writeNdefMessage(new NdefMessage(mimeRecord));
ndef.close();
Toast.makeText(getApplicationContext(), "WriteDone!", Toast.LENGTH_LONG).show();
}
catch (Exception e) {e.printStackTrace();}
}
}return true;}});
It is mandatory for all Android devices with NFC to correctly enumerate Ndef on NFC Forum Tag Types 1-4, and implement all NDEF operations as defined in this class.
Click to expand...
Click to collapse
. Read Data from NFC Tag
Initialize NfcAdapter, define PendingIntent with specific NfcAdapter.ACTIONS @onresume() & initialize NFC.Tag.
When you have instance of Tag then you can Read/Write.
Now, I get String of imageURI from NFC.Tag and set image to ImageView.
Code:
imageView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
if([B][COLOR="red"]tag [/COLOR][/B]!= null) {
Ndef ndef = Ndef.get([B][COLOR="red"]tag[/COLOR][/B]);
try {
ndef.connect();
NdefMessage ndefMessage = ndef.getNdefMessage();
[B]String nfcInfo = new String(ndefMessage.getRecords()[0].getPayload());
[COLOR="red"]imageUri [/COLOR]= Uri.parse(nfcInfo);[/B]
InputStream imageStream = getContentResolver().openInputStream(imageUri);
Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
imageView.setImageBitmap(selectedImage);
ndef.close();
Toast.makeText(getApplicationContext(), "ReadDone!", Toast.LENGTH_LONG).show();
}
catch (Exception e) {e.printStackTrace();}
} return true; } });

Hi guys, could anyone help me with this?
I am trying to develop an application that could automatic change the ringtone for incoming calls, because all the existed applications which has this feature could not works well on my Galaxy S7 Edge,
but then I found out is't not that easy to change ringtone on Galaxy S7 Edge.
I am tried with these code:
File sdFile = new File("/mnt/storage/26D9-150C/test.mp3");
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, sdFile.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, sdFile.getName());
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
Uri uri = MediaStore.Audio.Media.getContentUriForPath(sdFile.getAbsolutePath());
getContentResolver().delete(uri ,null ,null);//if not delete, maybe it will cause some error.
Uri newUri = this.getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
These code works fine on other devices, also on the Galaxy S7 Edge, you can see the new ringtone with code below, the ringtone changed into the target file, but when you received a phone call it's not the the ringtone that I set ! It's still the old ringtone before I run that code above. What's the problem ????? And I checked the ringtone from "Setting-Sound and vibrate-ringtone-incoming ringtone" it's never changed!!!
And I have granted the WRITE_SETTINGS permission already.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
private String getRealPath(Uri fileUrl) {
String fileName = null;
Uri filePathUri = fileUrl;
if (fileUrl != null) {
if (fileUrl.getScheme().toString().compareTo("content") == 0) {
Cursor cursor = mContext.getContentResolver().query(fileUrl, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
fileName = cursor.getString(column_index);
if (!fileName.startsWith("/mnt")) {
fileName = "/mnt" + fileName;
}
cursor.close();
}
} else if (fileUrl.getScheme().compareTo("file") == 0) {
fileName = filePathUri.toString().replace("file://", "");
if (!fileName.startsWith("/mnt")) {
fileName += "/mnt";
}
}
}
return fileName;
}
Then I searched everywhere, and find out that it seems samsung changed the system, the TYPE_RINGTONE will not effect on samsung anymore, is it true ? How could fix this problem ?
Why samsung change it like this ? It's really ****ty for developers!
Could anyone help me ? Thank you!

As I said, your app must be a system app (or a privileged app). Or else, adding this manifest to a normal app will not function at all and is useless.

Actually I think it's not the metter about the permission, the permission has been authorized, and the ringtone really changed into my ringtone on my device,
use these code you can see the default ringtone has changed after set.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
Also use a different application to check the default ringtone, it's changed into the one that I choosen.
But in fact the the ring of incoming call from the speaker never changed.
So I think samsung use a different ringtone database or whatever.
Oh, and all kinds of random ringtong tools not work on S7edge.
I will try to figure it out when I rooted my s7edge.
And before this, I found some information about samsung ring of alarm, so I think the call maybe the same reason, http://bbs.anzhuo.cn/thread-938419-1-1.html
anyway, thanks for reply.

Actually I think it's not the metter about the permission, the permission has been authorized, and the ringtone really changed into my ringtone on my device,
use these code you can see the default ringtone has changed after set.
private Uri getSystemDefaultRingtoneUri() {
return RingtoneManager.getActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE);//RingtoneManager.TYPE_ALL
}
Also use a different application to check the default ringtone, it's changed into the one that I choosen.
But in fact the the ring of incoming call from the speaker never changed.
So I think samsung use a different ringtone database or whatever.
Oh, and all kinds of random ringtong tools not work on S7edge.
I will try to figure it out when I rooted my s7edge.
And before this, I found some information about samsung ring of alarm, so I think the call maybe the same reason, http://bbs.anzhuo.cn/thread-938419-1-1.html
anyway, thanks for reply.

The permission has NOT been authorized. Please try to wrap your head around this. Your code is really messy.
https://github.com/android/platform_frameworks_base/blob/master/core/res/AndroidManifest.xml#L1597
Line 1600 states that you must have built the system through same firmware signature, "preinstalled" (priv-app), appop and pre-23 API
1595 states that it has a protection level of signature meaning that if the app isn't signed with the same signature as the ROM it won't be authorized to use that permission.
You can also try "pm grant YOUR_APP_NAME android.permission.WRITE_SETTINGS" in adb shell - and you will get an error saying it isn't a grantable permission.
Finally, if your app is a downloadable app from Play Store, this is the only caveat. Unless you request root to priv-app, THIS PERMISSION ISN'T GRANTED.
Java:
private boolean checkWriteSettingsPermissions() {
String permission = "android.permission.WRITE_SETTINGS";
int res = getContext().checkCallingOrSelfPermission(permission);
return (res == PackageManager.PERMISSION_GRANTED);
}
This is simple code that allows you to check whether your app is granted the permission.

Thank you for your patient.
1. I tried your code, and I was wrong about the permission, it says PERMISSION_DENIED. but I think this is not the problem for this question.
2. Did you tried my code ? The way that I asked for "WRITE_SETTINGS" is really work for ringtone, altho
Java:
private boolean checkWriteSettingsPermissions() {
String permission = "android.permission.WRITE_SETTINGS";
int res = getContext().checkCallingOrSelfPermission(permission);
return (res == PackageManager.PERMISSION_GRANTED);
}
said "PERMISSION_DENIED" , but it's really changed the ringtone ! If you not believe this, please try by yourself, and you can see from the setting - ring and vibrate - ringtone , you can see the result.
3. After several times try, I figure it out now... both way(manual and auto set by code "setMyRingtone()") of set the ringtone will work on the phone if have the permission of "Settings.System.canWrite(this)", but only work for the Ringtone of SIM 1, not work for SIM2. you can see the result form the setting page(only the ringtone for sim1 will change). if the ringtone still play the default ring of system, the problem probably is the metter of URI .
4. Before I post this thread, both way won't change the result of ringtone from the setting page of the phone, but as I said , you can see the result form another third part application.(this problem most probably is that I only use one SIM card at that time, did I put it into sim2? I don't know, already forget... but now if I put it into sim2 the ringtone form the setting page of the phone never change, but from the log of the code you can see the result is correct actually.)
5. Now the problem change into "How to create a standard URI and how to change the ringtone for SIM2". I will try to work on it.
6. Sorry for my pool English, and sorry for the "messy" code, I will improve it.
Anyway , thank you. you r the only one who helped me... Wish u luck.

I had the ringtone added on my MediaProvider but not set as the current one, I believe AOSP and TW deving is different.
When I mentioned "messy" I meant just copying and pasting the code into the forum, use
Code:
tags next time so it formats perfectly! :good::highfive:
