Catch ACTION_MEDIA_BUTTON - Intent from BT-Headset

Hi Community,
I have problems with the ACTION_MEDIA_BUTTON - Intent. I can't get my App receiving those actions and react on them.
In my AndroidManifest.xml I added the Intent-filter:
Code:
<intent-filter android:priority="42">
<action android:name="android.intent.action.MEDIA_BUTTON">
</intent-filter>
And in the onCreate-Method I registered a Receiver:
Code:
BroadcastReceiver receiver;
if (receiver == null) {
receiver = new ButtonReceiver();
}
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_MEDIA_BUTTON);
filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
registerReceiver(receiver, filter);
And the corresponding ButtonReceiver-class:
Code:
class ButtonReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent)
{
String intentAction = intent.getAction();
if (Intent.ACTION_MEDIA_BUTTON.equals(intentAction))
{
Log.d("ButtonReceiver", "I will handle buttons here");
//handle buttons
}
}
}
The app compiles fine and is also running without problems, BUT I never get to the "//handle buttons"-section.
For testing purpose I'm using my Jabra BT2015 and the provided earphones from HTC. Both don't work.
Every hint is very appreciated.

[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:

and this is source code:
Java Class:
Code:
public class ScienzeInfoNewsActivity extends Activity {

}
}
private FeedReader feedReader;

if (adapter != null)
adapter.clear();
try {

"rss.php"));
String feeds[][] = feedReader.getFeeds();
for (int i = 0; i < feeds.length; i++) {
adapter.add(new Link(feeds[i][0], feeds[i][1]));
}

</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.

[Q] Drawable not visible when camera preview is present

First of all, this is my first post here so hello everyone.
I'm writing an app that requires displaying a semi-transparent PNG layer over a camera preview. Everything was fine until I wanted to publish it and make sure it works also on Android 2.x. It seems that on older versions of Android, the camera preview causes the drawable (in my case, a subclass of ImageView) to not show. The whole screen is white, but the buttons are visible. When I get rid of the preview, it works just fine - the drawable is visible as it should. It works like this both on the emulator and on real devices.
Here is my code (the whole project is in the attachment). The most interesting and probably guilty class is CameraPreview. The code doesn't crash, there's also no exceptions or other behavior like this.
MainActivity.java
Code:
public class MainActivity extends Activity
{
CameraPreview mPreview;

{

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
mPreview = (CameraPreview)this.findViewById(R.id.cameraPreview);
}

Also, I'm not sure why the preview itself doesn't work. I've read that on Android 2.x emulators, the test image from the emulated camera is just this plain white by design, so I assumed it's ok. However, my friend tested the app on his phone with Android 2.3 and the preview appeared to be plain black. I guess it's a subject for a separate question, but maybe you'll notice something in the code.
I've spent a few days now to solve these two problems, so any clues would be really helpful. Thank you!

First of all, welcome to the forum.
Please do it as described here: http://forum.xda-developers.com/showthread.php?t=2439748
Post the code within
Code:
tags in the thread. Makes it easier for us. ;)
That way you'd get much more help (maybe from me ;)).

Could you provide at least a working example of camera preview for Android 2.x? I don't believe it can't be done. Does it need some kind of deprecated API to work correctly?

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.

[Q] nullpointer and wrap_content problems

Hello there
I got 2 problems:
Firstly, if I launch the following code on my device, I'm getting a nullpointer, and I got no idea why. ( I know it's sorta basic stuff)
Secondly, I want toset the screen height and lenght to wrap_content, it's red marked in the code...that is also not working..
Could you maybe help out a noob?
Code:
public class Game extends Activity implements OnClickListener{
Button start_time;
Button sec;
int i = 0;
TextView textview1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game);
start_time = (Button) findViewById(R.id.start_time);
start_time.setOnClickListener(this);
textview1 = (TextView) findViewById(R.id.textView1);
/*
sec = (Button) findViewById(R.id.sec);
sec.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
long totalTime = SystemClock.elapsedRealtimeNanos()- startTime;
Intent intent = new Intent(Game.this, MainScreen.class);
intent.putExtra("time",totalTime);
startActivity(intent);
}
});
*/
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.game, 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) {
Random r = new Random();
int x = r.nextInt([COLOR="Red"]wrap_content[/COLOR]);
int y = r.nextInt([COLOR="Red"]wrap_content[/COLOR]);
long startTime = SystemClock.elapsedRealtime();
i++;
View b = findViewById(R.id.start_time);
b.setX(x);
b.setY(y);
if (i == 1 ) {
b.setX(+9);
b.setY(+5);
}
if (i == 2 ) {
b.setX(x);
b.setY(y);
}
if (i == 3 ) {
b.setX(x);
b.setY(y);
}
else if (i == 4) {
long difference = SystemClock.elapsedRealtime() - startTime;
Intent intent = new Intent(Game.this, MainScreen.class);
intent.putExtra("time",difference);
// Toast.makeText(getApplicationContext(), getIntent().getStringExtra("time"), Toast.LENGTH_LONG).show();
textview1.setText(getIntent().getStringExtra("time"));
finish();
}
}
}

For the wrap_content one, you need to set that property to the view that holds the integer text, you can't set a height and width properties to an integer, only a view or other widgets such as buttons. So for you you should set the properties of the view with ID start_time to wrap_content for width and height - recommend doing this in the layout XML instead of java code.
I'm guessing that if you sort that out your null pointer will disappear.
Additionally in your public onClick(View v) method you should check the ID of the view before doing any function code, this means you can have multiple objects using the same listener.
So this:
Code:
@Override
public void onClick(View v) {
Random r = new Random();
... etc
Should become this:
Code:
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.start_time:
Random r = new Random();
... etc

tahnks @Jonny for your answer, I changed the code, but now, my button isn't placed randomly on each click anymore, and I'm getting the nullpointer again. have a look:
Code:
public class Game extends Activity implements OnClickListener{
Button start_time;
Button sec;
int i = 0;
TextView textview1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game);
start_time = (Button) findViewById(R.id.start_time);
start_time.setOnClickListener(this);
textview1 = (TextView) findViewById(R.id.textView1);
/*
sec = (Button) findViewById(R.id.sec);
sec.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
long totalTime = SystemClock.elapsedRealtimeNanos()- startTime;
Intent intent = new Intent(Game.this, MainScreen.class);
intent.putExtra("time",totalTime);
startActivity(intent);
}
});
*/
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.game, menu);
return true;
}
@Override

// 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) {
Random r = new Random();
int x = r.nextInt(+1);
int y = r.nextInt(+1);
long startTime = SystemClock.elapsedRealtime();
i++;
View b = findViewById(R.id.wrap_content);
b.setX(x);
b.setY(y);
if (i == 1 ) {
b.setX(+9);
b.setY(+5);
}
if (i == 2 ) {
b.setX(x);
b.setY(y);
}
if (i == 3 ) {
b.setX(x);
b.setY(y);
}
else if (i == 4) {
long difference = SystemClock.elapsedRealtime() - startTime;
Intent intent = new Intent(Game.this, MainScreen.class);
intent.putExtra("time",difference);
// Toast.makeText(getApplicationContext(), getIntent().getStringExtra("time"), Toast.LENGTH_LONG).show();
textview1.setText(getIntent().getStringExtra("time"));
finish();
}
}
}

thank you. I'm really happy, there exists such great help

i have now changed the view start_time to a button...because it actually IS a button (im stupid) but now, when I click on the button, it moves completely out of the screen, and if not, instead of getting the time, the app stopps again with nullpointer. It should stay in the screen, placed randomly on click and after some clicks, I want to recieve the elapsed time. what is this?
code:
Code:
public class Game extends Activity implements OnClickListener{
Button start_time;
Button sec;
int i = 0;
TextView textview1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game);
start_time = (Button) findViewById(R.id.start_time);
start_time.setOnClickListener(this);
textview1 = (TextView) findViewById(R.id.textView1);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.game, menu);
return true;
}
@Override

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onClick(View v) {
Random r = new Random();
int x = r.nextInt(R.id.wrap_content);
int y = r.nextInt(R.id.wrap_content);
long startTime = SystemClock.elapsedRealtime();
i++;
Button b = (Button) findViewById(R.id.start_time);
b.setX(x);
b.setY(y);
if (i == 1 ) {
b.setX(+9);
b.setY(+5);
}
if (i == 2 ) {
b.setX(x);
b.setY(y);
}
if (i == 3 ) {
b.setX(x);
b.setY(y);
}
else if (i == 4) {
long difference = SystemClock.elapsedRealtime() - startTime;
Intent intent = new Intent(Game.this, MainScreen.class);
intent.putExtra("time",difference);
// Toast.makeText(getApplicationContext(), getIntent().getStringExtra("time"), Toast.LENGTH_LONG).show();
textview1.setText(getIntent().getStringExtra("time"));
finish();
}
}
}
and the xml:
Code:

I'm not familiar with the nextInt() function (I can look it upp later when I'm home) but I'm pretty sure you shouldn't be parsing a views ID as one of its conditions - eg you're doing nextInt(R.id.wrap_content), are you sure that's right?
