TextureView playing video turns black after onPause

I am using a TextureView to play a video in a ListView. The TextureView itself works perfectly, however, if I press the home button and reenter the application a few times, the TextureView turns black (though the audio continues to play). If I exit and reenter again, the TextureView turns white (or maybe transparent, as white is the colour of my background).
Here is my code:
holder.instagramTextureView
.setSurfaceTextureListener(new SurfaceTextureListener() {
#Override
public void onSurfaceTextureUpdated(
SurfaceTexture surface) {
// TODO Auto-generated method stub
}
#Override
public void onSurfaceTextureSizeChanged(
SurfaceTexture surface, int width, int height) {
// TODO Auto-generated method stub
}
#Override
public boolean onSurfaceTextureDestroyed(
SurfaceTexture surface) {
// TODO Auto-generated method stub
return false;
}
#Override
public void onSurfaceTextureAvailable(
SurfaceTexture surface, int width, int height) {
final Surface s = new Surface(surface);
try {
holder.mMediaPlayer = new MediaPlayer();
holder.mMediaPlayer.setDataSource(post
.getMedias().get(0)
.getMediaUrlVideomp4StandardRes());
holder.mMediaPlayer.setSurface(s);
holder.mMediaPlayer.prepare();
holder.instagramVideoVolume = 0f;
holder.mMediaPlayer.setVolume(
holder.instagramVideoVolume,
holder.instagramVideoVolume);
//holder.mMediaPlayer.setOnBufferingUpdateListener(this);
holder.mMediaPlayer
.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(
MediaPlayer mp) {
// To play:
mp.reset();
try {
mp.setDataSource(post
.getMedias()
.get(0)
.getMediaUrlVideomp4StandardRes());
mp.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch
// block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch
// block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch

e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch

e.printStackTrace();
}
// <--- Here comes a call to
// "To Resize" which is shown
// right above this code
mp.start();
}
});
// holder.mMediaPlayer.setOnPreparedListener(this);
//holder.mMediaPlayer.setOnVideoSizeChangedListener(this);
holder.mMediaPlayer
.setAudioStreamType(AudioManager.STREAM_MUSIC);
holder.mMediaPlayer.start();
holder.instagramTextureView
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (holder.instagramVideoVolume == 1) {
holder.instagramVideoVolume = 0f;
holder.mMediaPlayer
.setVolume(
holder.instagramVideoVolume,
holder.instagramVideoVolume);
} else {
holder.instagramVideoVolume = 1f;
holder.mMediaPlayer
.setVolume(
holder.instagramVideoVolume,
holder.instagramVideoVolume);
}
}
});
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block

} catch (IllegalStateException e) {

}
});

Problem was making a new mediaplayer each time the surface is available. Not quite sure how this worked, but this was the problem. Instead, I create the mediaplayer outside of this listener.

From my research, textureView.getSurfaceTexture() returns null onResume(). What I did was reattach a listener to it in onResume().
TextureView textureView;
/*....
Usual stuff
*/
public void onPause(){
super.onPause();
//... destroy or disable image producer
}
public void onResume(){
super.onResume();
textureView.setSurfaceTextureListener(/*another listener*/);
}
Then, perform your usual things on onSurfaceTextureAvailable()

The black screen and audio playing happened with me when I did not release the MediaPlayer object.

Change pause button of audio player on oncomplete listener in android

I'm loading audio sounds into a listview, I play them.When the audio playing is done, i want to change that specific sound's pause button to play button again.
here is my code to play sounds
soundChild.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
player.setDataSource(url);
// file.close();
player.prepare();
player.setLooping(false);
// player.start();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (player.isPlaying()) {
if (player != null) {
player.pause();
// Changing button image to play button
soundChild.setImageResource(R.drawable.playbutton);
}
} else {
// Resume song
if (player != null) {
player.start();
// Changing button image to pause button
soundChild.setImageResource(R.drawable.pausebutton);
}
}
}
});
player.setOnCompletionListener(new OnCompletionListener() {
#Override public void onCompletion(MediaPlayer mp) { // TODO
// Auto-generated method stub player.release(); player=null;
Toast.makeText(_context, "complete", Toast.LENGTH_LONG).show();
soundChild.setImageResource(R.drawable.playbutton);
player.reset();
} });
But on complete listner the imageview of player button is never changed back to play imageview again. I doin't know where i'm doing wrong, because if onComplete is being called then imageview background should also change.please help.

Usually You have to call requestLayout before:
soundChild.requestLayout();
soundChild.setImageResource(R.drawable.playbutton);
and then after changing the image
soundChild.invalidate();
What else could You try? If it doesn´t work, You can also try:
soundChild.setImageDrawable(context.getResources().getDrawable(R.drawable.playbutton));
Because, like described in the API for setImageResource:
This does Bitmap reading and decoding on the UI thread, which can
cause a latency hiccup
Also, what it is possible, You have to call it in on ui thread:
runOnUiThread(new Runnable() {
#Override
public void run() {
soundChild.setImageResource(R.drawable.playbutton);
}
});
and call this in onCompletion.

Play Audio Streaming with Android

Require develop streaming audio playback with mediaplayer on android.
Any ideas ?!
Thanks
I try the following code:
play.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String url = "http://stream.radiosai.net:8002/"; // your URL here
MP.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
MP.setDataSource(url);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
MP.prepareAsync();
MP.start();
}
});
The above does not work Error deploying

MP.start();
Should be called after the mediaplager is ready, in setOnPreparedListener.
When you create MediaPlayer object, add prepared listener
MP.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});

The German computer magazine C't recently published an article with the source code for an Android alarm clock radio. You can download the project files here. I think this contains everything that you need.

Play Rtsp audio stream in Android media player

I want to play an RTSP audio stream in Android media player. I was trying to directly bind to an RTSP link in media player. Sometimes it's playing fine, but now it didn't play and showed a media player error:
MediaPlayer(808): error (1, -2147483648).
Where is the problem?
Here is my some part of the code:
public class PlayRadio extends AsyncTask<Void, Void, Void> {
#Override
protected Void doInBackground(Void... arg0) {
// TODO Auto-generated method stub
setDataSource(rtspUrl);
Log.e("inside doinbackground....", path);
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
player.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
player.start();
Toast.makeText(getApplicationContext(), "starting..", Toast.LENGTH_LONG).show();
}
});
player.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
}
private void setDataSource(String path2) {
// TODO Auto-generated method stub
player=new MediaPlayer();
try {
Uri a =Uri.parse("rtsp://stream.rtm.swiftserve.com/live/rtm/rtm-ch010");
player.setDataSource(getApplicationContext(),a);
player.prepareAsync();
}
catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//Log.e("tempPath", tempPath);
}

This error MediaPlayer(808): error (1, -2147483648) simply tells that your the video file you are playing is not supported by your device.
Generally RTSP links uses .sdp format which is currently not supported by Android devices.
Please check here Supported Media Formats

break;

There are different methods to realize it.
Using LocalBroadcastManager
Using an application to track the status of your service, i.e Song name, length, ...
Using SharedPreferences
IMHO, I think using a LocalBroadcastManager is more cleaner.
- Send a broadcast message to the service
- When the service receives the message, let it broadcast its status.
