[Q]Android Bluetooth - mHandler and manageConnectedSocket errors

[Q]Android Bluetooth - mHandler and manageConnectedSocket errors - Java for Android App Development

Hi! I am beginner in Android programming. I would like to learn how to send a string between 2 devices via Bluetooth. I was trying to write a code on the base of page http://developer.android.com/guide/topics/connectivity/bluetooth.html
I got 3 errors. The first one is, that the MainActivity is underlined red in the following row:
Code:
public class MainActivity extends Activity {
It says: 'The blank final field mHandler may not have been initialized'
The other 2 errors are shown in the AcceptThread and ConnectThread classes. The following row is underlined red:
Code:
manageConnectedSocket(socket);
It says: 'The method manageConnectedSocket(BluetoothSocket) is undefined for the type AcceptThread' and 'The method manageConnectedSocket(BluetoothSocket) is undefined for the type ConnectThread'
Could you please tell me, how to fix the problems and explain me, what were the problems? Thanks in advance.

[Q] Item separator in ListView fails! Why?

i have a problem with ListView, i don't view line separator for each item, why ? see where is mouse pointer:
h_t_t_p://tinyurl.com/2vqg52n
and this is source code:
Java Class:
Code:
public class ScienzeInfoNewsActivity extends Activity {
private class Link {
private String title;
private String href;
public Link(String title, String href) {
this.title = title;
this.href = href;
}
public String toString() {
return title;
}
public String getHref() {
return href;
}
}
private FeedReader feedReader;
private ArrayAdapter<Link> adapter;
private ListView list;
public void initialize() {
adapter = new ArrayAdapter<Link>(this, R.layout.textview);
list = (ListView) findViewById(R.id.ListView01);
list.setAdapter(adapter);
}
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initialize();
loadFeeds(adapter);
setAllListener();
}
private void setAllListener() {
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> a, View v, int position,
long id) {
String link = adapter.getItem((int) id).getHref();
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(link));
startActivity(intent);
}
});
Button exit = (Button) findViewById(R.id.Button02);
exit.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
ScienzeInfoNewsActivity.this.finish();
}
});
Button refresh = (Button) findViewById(R.id.Button01);
refresh.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
loadFeeds(adapter);
}
});
}
private void loadFeeds(ArrayAdapter<Link> adapter) {
if (adapter != null)
adapter.clear();
try {
feedReader = new FeedReader(new URL(
"rss.php"));
String feeds[][] = feedReader.getFeeds();
for (int i = 0; i < feeds.length; i++) {
adapter.add(new Link(feeds[i][0], feeds[i][1]));
}
} catch (Exception e) {
Toast.makeText(this, e.getMessage(), Toast.LENGTH_LONG).show();
}
}
}
R.layout.textview:
Code:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="h_t_t_p://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16sp" >
</TextView>
I load entry item with this function loadFeeds()
If i select one of the items without a separator, it just one item.
Thanks for any reply.

Pass Connection Between Intents

I am building an android application to do various queries on my MySQL database. Once a successful login has returned on the main activity, I create a new Intent that holds search and query options. Here's the issue I am having. I keep getting a null pointer exception on stmt = con.createStatement(); Below is my logcat:
Code:
08-20 16:12:07.359 654-810/com.android.exchange D/ExchangeService: !!! deviceId unknown; stopping self and retrying

I'm curious whether it is better practice to close the connection and reopen it in the new intent? Or pass the connection between intents somehow?
Any input would be greatly appreciated!

wait...
Here are snippets of my code to help debug.
Code:
[user=439709]@override[/user]
public void onClick(View view) {
if(view.getId() == R.id.LoginButton) {
Toast.makeText(getApplicationContext(), "Attempting Connection", Toast.LENGTH_SHORT).show();
//Spawn new thread
new Thread(new Runnable() {
public void run() {
if(net.execLogin(mUserInput.getText().toString(), mPassInput.getText().toString())) {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Connected to Database", Toast.LENGTH_LONG).show();
}
});
//start new activity
Handler handler = new Handler(Looper.getMainLooper());
handler.post(new Runnable() {
[user=439709]@override[/user]
public void run() {
Intent intent = new Intent(LoginActivity.this, ControlActivity.class);
startActivity(intent);
}
});
}
else {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "Connection Failed :(", Toast.LENGTH_LONG).show();
}
});
}
}
}).start();
}
}
And here is the new activity started by the above code:
Code:
package com.example.testapplication;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;
public class ControlActivity extends Activity implements View.OnClickListener {
private ArrayList<Hardware> list = new ArrayList<Hardware>();
EditText mEditText;
ListView mListView;
[user=439709]@override[/user]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_control);
setupPage();
}
public void setupPage() {
Button search = (Button)findViewById(R.id.search);
search.setOnClickListener(this);
mEditText = (EditText)findViewById(R.id.editText);
mListView = (ListView)findViewById(R.id.listView);
}
[user=439709]@override[/user]
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.control, menu);
return true;
}
public void onClick(View view) {
if(view.getId() == R.id.search) {
new Thread(new Runnable() {
public void run() {
list = new Networking().Search("Type", mEditText.getText().toString());
}
}).start();
ArrayAdapter<Hardware> adapter = new ArrayAdapter<Hardware>(this, android.R.layout.simple_list_item_1, list);
adapter.notifyDataSetChanged();
mListView.setAdapter(adapter);
if(list == null) {
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getApplicationContext(), "0 Results Yielded :(", Toast.LENGTH_SHORT).show();
}
});
}
}
}
}
And here is the code I use to connect and query the database
Code:
import java.sql.*;
import java.util.*;
public class Networking implements DbQuery {
private static final String DRIVER = "org.mariadb.jdbc.Driver";
private static final String URL = "jdbc:mysql://146.187.16.32/Peirce";
ArrayList<Hardware> ara = new ArrayList<Hardware>();
Database db = new Database();
Hardware h1;
Connection con = null;
Statement stmt = null;
public boolean execLogin(String uName, String pWord) {
try {
Class.forName(DRIVER);
con = DriverManager.getConnection(URL, uName, pWord);
if(!con.isClosed()){
return true;
}
return false;
}catch(SQLException e) {
e.printStackTrace();
}catch(ClassNotFoundException e) {
e.printStackTrace();
}
return false;
}
public ArrayList<Hardware> Search(String arg, String target) {
try {
stmt = con.createStatement(); //throws null pointer exception
ResultSet rs = stmt.executeQuery("Select * from " + db.getTable() + " where " + arg + "='" + target + "';");
while(rs.next()) {
ara.add(new Hardware(rs.getString("Type"), rs.getString("Make"), rs.getString("Model"), rs.getString("Serial"), rs.getString("Comments")));
}
return ara;
}catch(SQLException e) {
e.printStackTrace();
}catch(NullPointerException e) {
e.printStackTrace();
}
return ara;
}

nevermind
i have figured it out.

I tried in every way but I can not get out
Someone can give me a hand?
Thanks

The problem is that with a surface view, the getDrawingCache() method always returns null or a black bitmap...
I got it working in my app by creating a new Canvas with the same size as your surface view and then call surfaceView.onDraw(canvas), passing the new one. You can then write it to a file via its bitmap.
And remember, depending on how intense your onDraw method is you may need to do the saving in an Async task.

Can anybody help me?
Lot's of thank's!

Don't know whether you idea is possible, but please DO NOT code an empty catch part. Something like e.printStackTrace() and e.getMessage() AT LEAST.

Is Correct NOW?
Thank's

It might be correct, but senseless, because you never see e.getMessage(). So u could use Log.e(TAG, e.getMessage()).
But by the way, it'd be great if you'd post your log here and before read it.

You define a variable of type WindowManager but you never assign any object to it.
Add this before the try:
Code:
wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE);

Maybe you can find some hints in the code of the RoundR app which does actually do what you want to achieve: https://github.com/MohammadAdib/Roundr

[Q] Change text in another activity on click. how?

Hi there
I am new to this forum as an User, and I am also new to Java and Android, in developing ways. Sorry if there are any language or other mistakes.
So I am trying to make an app for a 'final' school project, which has the follow use:
The user sees an picture, a 'next' (and a 'finish') button. there are 11 pictures (user only sees one)(in the code there are for testing purposes only 3) when the user clicks 'next', the pic no. 2 appears, if he clicks another time next, the pictuer no. 3 appears and so on. (If he clicks finish, he should see a messages which shows him the text: "you've made it until pic xy" but i'm not so far yet.) I tried to do it with this code, but i failed.
Code:
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
public class VisusActivity extends Activity implements OnClickListener {
ImageView testanzeige;
Button next;
Integer[] bildanzeige = {
R.drawable.visustest,
R.drawable.v2,
R.drawable.v3
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_visus);
testanzeige = (ImageView)findViewById(R.id.testanzeige);
next = (Button)findViewById(R.id.next);
next.setOnClickListener(this);
next.setOnClickListener(this);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.visus, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
try {
//Toast.makeText(this, getResources().getDisplayMetrics().toString(), Toast.LENGTH_LONG).show();
testanzeige.setImageResource(bildanzeige[0]);
}catch(Exception e){
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
}
};
public void onClick1(View v) {
try {
//Toast.makeText(this, getResources().getDisplayMetrics().toString(), Toast.LENGTH_LONG).show();
testanzeige.setImageResource(bildanzeige[2]);
}catch(Exception e){
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
}
}
}
so what have I to do? no tutorial shows up exactly my problem ( I think it's such a basic thing everyone can do it^^)
thx

I have Make Fresh Java That will help You

Toast.makeText(getApplicationContext(), "Your Final Text", Toast.LENGTH_LONG).show();

});
}
}
Layout
Code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="@+id/imagey"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/avatar_default_1" />
<Button
android:id="@+id/nextey"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
In Your Java You can use Button.setOnClickLiestner(new View.OnClickLiestner It will bit easier than it because When We Implement Anything in Your Class we need delcare methods @override somethings you can use int to change Image
In My Java I have int values that will change every click on Button according to values it will change imageview you have write java that is tough from Me you can use my one it will bit easier Ok

Thank you new problem
Thank you so very much AndroidFire withoup you i've wouldn't made it this far. So you say I can use your code (with your name in it) in my Project?
AndroidFire said:

Click to expand...

Now while this problem is solved another problem has come up.
As I told you in my first thread, there is a finish button. It has this use:
when user clicks next 2 times (so if he made it until the 3rd picture) and then clicks finish, he'll Return to the main activity, and instead of the text 'Klicke auf start um zu beginnen' (click on start to begin) the text 'you made it until the 3rd picture' should show up.
If he clicked Next 5 times (6th picture) and clicks finish, he also returns to the main activity, but the text is 'you made it until the 5th picture'.
And so on with the others.
now i dont know, how to implement multiple buttons, how can I learn that? also how did you learn to code, AndroidFire? It's such a masterpiece *-*
I've tried this, but I failed.
the red lines are those, which I made at my own but they unfortunately don't work

I'm assuming you declared your activity in the Manifest?

Click to expand...

uhm I think so.
Edit: there are 2 activity-groups in my manifest, so I think they've been declared automatically?

After looking at your code further, you are using onClick methods but aren't implenting an onClickListener. Are your buttons working at all?

yes, they are working fine. I just dont know how to change the text.

rodentooth said:

There are two ways I can think of to solve this one.
The first is to create an Application class, declare that in the manifest, and add a variable in there to save how many images have been seen. Just set it in the one activity and in the other read it, and if it's 0, show the start message, and if it's greater than 0 show the message you want.
The cooler way is to use startActivityForResult to go to the picture viewing activity. The picture viewing activity keeps track of how many the user saw and then, when they leave:
Code:
Intent returnData = new Intent();
returnData.putExtra("PICTURES_SEEN", count);
setResult(RESULT_OK, returnData);
Then, in the first activity:
Code:
@Override
protected void onActivityResult (int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
int picturesSeen = data.getExtra("PICTURES_SEEN");
// do stuff
}
}
Hopefully that's helpful.
(There's a page in Google's API called "Getting a Result from an Activity" but I can't link to it because I'm a spammernew.)
