Try this:
Open a command prompt window and type 'adb kill-server' (Without quotation marks). When it's done, type 'adb start-server'
If that doesn't work, try restarting eclipse, your computer and your device. I've had this problem before, and usually one of these steps solves it.

How make application with maps? (apiKey)

Hi, I am new in xda-developers forum. I have written my first simple application which uses GPS. Now I want to use Google Maps. Is problem because it want apiKey. My apiKey is in Google Code Api's Console. There is Android apps:
8A5:....:72:88:AE;com.borneq.heregpslocation and ApiKey : AIzaSyCh0XWRIXaTizxYcnWO8K7eFLZEysfGJvM (it is public or private?)
I modified three file to do with maps:
* AndroidManifest.xml:
Code:
<permission
android:name="com.borneq.heregpslocation.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-feature
android:glEsVersion="0x00020000"
android:required="true" />
<uses-permission android:name="com.borneq.heregpslocation.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Code:
<uses-library android:name="com.google.android.maps" />
Code:
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyCh0XWRIXaTizxYcnWO8K7eFLZEysfGJvM" />
Second file is activity_main.xml :
Code:
<com.google.android.maps.MapView
android:id="@+id/mapview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:apiKey="AIzaSyCh0XWRIXaTizxYcnWO8K7eFLZEysfGJvM"
android:clickable="true" />
Third is .MainActivity.java :
import com.google.android.maps.MapActivity;
public class MainActivity extends MapActivity implements OnClickListener {
Click to expand...
Click to collapse
Previously used controls I commnted
Project compiles but application breaks at start. I attach source: zipped program and logCat
Thanks!

The app crashs in line 77 of MainActivity. It's a NullPointerException.
Code:
boolean isGps = locationManager.isProviderEnabled("gps");
The reason for the crash is that in onCreate you commented this line out:
Code:
locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Due to this the variable locationManager is null and it crashes later because it cannot handle a null value. Just uncomment the line from onCreate which I pasted above. That's it.
How did I know that? It's in the logcat:
Code:
Caused by: java.lang.[B]NullPointerException[/B]
at com.borneq.heregpslocation.MainActivity.setButtonState([B]MainActivity.java:77[/B])
This guide might help you understand logcats (focus on that part of the guide): [GUIDE] Debugging apps You'll definitely need that knowledge if you want to do serious Android development. The earlier you learn it the better. Good luck.

Thanks, I remove by comment old controls and not noticed that comment also locationManager (!)

I correct; removed reference to commented controls and I don't have error but I can't see maps
Is "class MainActivity extends MapActivity" but np map, only lattice

[Q] how to start application on boot / startup

I tried to follow the tutorials on internet to start application start at boot time , but it does not seems to work.
i followed the tutorial, i also downloaded and installed this example source code, but this application wont work, its not showing at startup, is that something wrong with my device ? or is it has a technical changes like OS forbid it to run or something?

You need to create boot receiver:
public class BootExampleReciever extends BroadcastReceiver
{
@override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
you need to add the following permission to the manifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
and to declare the receiver as well:
<receiver android:name=".BootExampleReciever">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>

[Q] My android studio giving me errors and not working.

Well I posted it in android studio forum here but I don't know if it belongs to here..
any way -
READ ONLY EDIT DOWN!!
Okay, so I can't develop nothing as my Android Studio decided to. My all project is full of errors, unknown errors caused by Android Studio.
note: my files are correct, it is an other problem because even if I will import something from google codes it will have errors.
When I import a project everything's fine, but then after indexing and such things, all sudden everything is red and shouldn't be.
My errors for example are :
Code:
button1.setOnLongClickListener(new View.OnLongClickListener() {
....
....
}
Well shouldn't be error but :
Code:
cannot resolve symbol setOnLongClickListener
Another example:
Code:
button1=(Button) findViewById(R.id.button1);
I used this exact code for other button, seems right, I always using this line, it was fine until my Android Studio decided to give me some hard time, this line is full by errors and they are:
Code:
Unknown class: 'button1' , invalid method declaration; return type required, missing method body, or declare abstract
and there are like 20 errors that shouldn't be, things I tried:
1.deleting iml files , .idea folder - worked for a while but now it happened again and it doesn't fix it.
2.reinstalling android studio and then importing project.
3.upgrading android studio version to 1.3
4.restarting my pc.
5.importing project to an other pc, happened after a while.
6.Invalidate caches/ restart.
7.Changing module in project structure - I changed it back to how it was (it didn't help) and I think it caused the manifest error down..
My Module:app build.gradle:
Code:
apply plugin: 'com.android.application'
android {
compileSdkVersion 22
buildToolsVersion '22.0.1'
defaultConfig {
applicationId "firstappdevelopments.david.reactiontime"
minSdkVersion 9
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.2.1'
}
Also I noticed now, my Manifest file as an error in
Code:
android:name=".MainActivity"
says it has no default structure. something like this. here is the full normal code:
Code:
<?xml version="1.0" encoding="utf-8"?>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
</manifest>
Please, if someone knows what is the problem or what can I else do, just say, and I am sorry about my English, thank you all.
EDIT!!!:
I deleted this lines:
Code:
connect.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
bluetooth = BluetoothAdapter.getDefaultAdapter();
if (bluetooth != null) {
if (bluetooth.isEnabled()) {
bluetooth.startDiscovery();
Set<BluetoothDevice> bondedSet = bluetooth.getBondedDevices();
if(bondedSet.size() > 0){
for(BluetoothDevice device : bondedSet){
newDevicesListView.setVisibility(View.VISIBLE);
mArrayAdapter.add(device.getName() + "\n" + device.getAddress());
}
}else{
mArrayAdapter.add("No Devices");
}
}
} else {
textview.setText("bluetooth is disabled, enabling.");
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, RESULT_OK);
}
} else{
textview.setText("Bluetooth is not supported.");
}
}
});
AND SUDDENLY ALL THE ERRORS DISSAPPEARED , ANY IDEAS? - The errors was in other lines..

I dont understand the 2nd one but i cann help u in button prblm..
try this
Button button1 = (Button)findViewById(R.id.blahblah);
and button1.setOnLongClickListenetblahblahnla.......
try and let me know

App indexing: how to?

I'm implementing app indexing and I think I'm missing something, but I don't know what.
Following the guide I added my intent-filters to the app and implemented what's needed in my activity.
my application's package is com.towers.mypackage and the associated website (where I didn't put the link rel meta-tag yet, since I'm just testing) is www.mypackage.com
I saw the following intent-filter example in the guide
HTML:
<activity
android:name="com.example.android.PetstoreActivity"
android:label="@string/title_petstore">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" />
<data android:scheme="https" />
<data android:host="www.examplepetstore.com" />
</intent-filter>
</activity>
so I wrote mine in this way:
HTML:
<activity
android:name=".ActivityForAppIndexing"
android:label="@string/title_activity"
android:screenOrientation="portrait" >
<intent-filter android:label="@string/app_name">
<data android:scheme="android-app"
android:host="com.package.myappname" />
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http"
android:host="www.mywebsite.com" />
<data android:scheme="https"
android:host="www.mywebsite.com" />
</intent-filter>
</activity>
Also, I wrote a content provider in order to parse the URI
HTML:
<provider
android:name=".contentproviders.HotelDetailsContentProvider"
android:authorities="com.towers.mypackage" >
</provider>
which should map the URIs as follows:
Code:
private static final String BASE_PATH = "https";
private static final String AUTHORITY = "com.towers.mypackage";
public static final Uri CONTENT_URI = Uri.parse("android-app://" + AUTHORITY
+ "/" + BASE_PATH);
I'm testing the implementation via command line using the following adb command:
Code:
adb shell am start -a android.intent.action.VIEW -d "https://mypackage.com?hotel_id=135738" com.towers.mypackage
and IT WORKS. The app gets automatically opened with the right activity and the right parameters. When the app starts the onNewIntent method gets called:
Code:
protected void onNewIntent(Intent intent) {
String action = intent.getAction();
String data = intent.getDataString();
if (Intent.ACTION_VIEW.equals(action) && data != null) {
String recipeId = data.substring(data.lastIndexOf("/") + 1);
Uri contentUri = HotelDetailsContentProvider.CONTENT_URI.buildUpon()
.appendPath(recipeId).build();
bundle = new Bundle();
bundle.putString("pictureUrl", "");
//showRecipe(contentUri);
}
}
(I got it of course from the examples, that's why it talks about recipes)
But I wonder: what should I do? Get data from the intent with a
Code:
getIntent().getData().getQuery()
or use the ContentProvider and get them from the URI?
Also, I'd like to test with the Google Search Console and the "View as google" funcionality if everything is okay. I uploaded my APK and saw an URI is requested.
Now, in the "testing your app" section of the documentation I saw that the links like http://mypackage.com?hotel_id=135738 are referred as "deep links" while those like android-app://com.towers.mypackage/https/mypackage.com?hotel_id=135738 are referred as "URI". Am I right?
The "View as google" funcionality asks for a URI but I don't know how to create one. Also, I wonder how this URI is passed to the app and I'm pretty sure I'm getting very confused about this all URI/deepLink thing, and can't find relief in the documentation.
Where and when should I use the URI? Where and when should I use the deepLink? I guess that since I'm going to put the link rel=URI in my webpages then the app will be called in the app indexing with the URI and not with the URL of the page. But if it's so... why is the adb shell am start -a android.intent.action.VIEW -d command used for testing with the URL and not the URI? Should my app be able to get and handle URIs or URLs? And how?
I thought I had understood something about app indexing, but today I'm starting to think I got it all wrong since I started. That's why I ask you for help in answering the questions above, and possibly sheding a light on all this URL/URI/intent-filter/ContentProvider mess.
I already talked about this on Stackoverflow and got two answers, plus a lot of comments. But I wasn't able to get anything from that, App indexing remains a mysterious monster to me :-/
Did anyone of you manage to make this kind of things work? And how?
Thank you everybody, really.
