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

e.printStackTrace();
}
}
});

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.

playing sdcard video on textureview

I'm trying to play a video that I have on the sdcard of my device using Textureview, which according to the documentation, is the best solution to further transform the video, the problem is that when I put the path of an Internet video me working correctly , and when I put my route sdcard me the video is black, but the sound if it works, is very rare. I attached the code if you can help me, I've been searching like crazy but I find it can be happening, thanks in advance. regards
public class tres extends Activity implements TextureView.SurfaceTextureListener {
private MediaPlayer mp;
private TextureView textureview;
private String Path = "video.mp4";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tres);
textureview = (TextureView) findViewById(R.id.vista_video);
textureview.setSurfaceTextureListener(this);
}
#Override
public void onSurfaceTextureAvailable(SurfaceTexture surface, int width,
int height) {
// TODO Auto-generated method stub
Surface s = new Surface(surface);
try {
mp= new MediaPlayer();
mp.setDataSource(Environment.getExternalStorageDir ectory()+"/" + Path);
mp.setSurface(s);
mp.prepare();
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.start();
} 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();
}
}

im having exact the same issue.
current workarround is a running webserver app on the same device and setting the DataSource of my mediaPlayer instance to localhost.
but thats not the solution im hoping to find.

Why animation is not displaying front while streaming in android

I am doing an radio streaming app. I am trying to display some loading bar frame by frame animation before my stream begins. but the animations starts after playing the stream only. How could i show my anim before stream loads. Here is my code snippet. Help is appreciated...
bhajan_play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo Info = conMan.getActiveNetworkInfo();
if (Info == null) {
Toast.makeText(BhajanStream.this, "POOR SIGNALS ",
Toast.LENGTH_LONG).show();
// startActivity(new Intent(Settings.ACTION_WIFI_SETTINGS));
}
else {
loadanim.setBackgroundResource(R.drawable.loader_1);
loadanim.setBackgroundResource(R.anim.loadanim);
loadanimation = (AnimationDrawable) loadanim
.getBackground();
loadanimation.isVisible();
effectanim.setBackgroundResource(R.drawable.effect_1);
effectanim.setBackgroundResource(R.anim.musiceffect);
effectanimation = (AnimationDrawable) effectanim
.getBackground();
bhajan_play.setBackgroundResource(R.drawable.bhajan_start);
bhajan_play.setVisibility(View.GONE);
bhajan_stop.setVisibility(View.VISIBLE);
loadanim.setVisibility(View.VISIBLE);
effectanim.setVisibility(View.VISIBLE);
}
try {
mediaPlayer.reset();
mediaPlayer.setDataSource(rs_bhajan_uri);
} catch (IllegalArgumentException 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();
}
try {
mediaPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mediaPlayer.start();
}
});
}
protected void onPreExecute() {
// UI work allowed here
loadanimation.start();
}

You should call prepareAsync() rather than just prepare().
From the MediaPlayer documentation:
For streams, you should call prepareAsync(), which returns
immediately, rather than blocking until enough data has been buffered.
(Calling prepare will block your Ui Thread until the data is prepared, meaning that updating your views has to wait until the preparation is done)
Example implementation:
mediaPlayer.prepareAsync();
mediaPlayer.setOnPreparedListener(new OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});

Using a thread with media player

I'm trying to get this to work the way I want and it just won't I think I had it at some point but I was trying to fix something else and changed a few things and messed it up. Basically I'm this button is a play button. It is supposed to run media player through another thread so that it reacts and buffers faster. Issue is after it plays through to the end and I click play it is ended and keeps running the onCompletion. When I would like it to start over and play from the beginning again.
public void onClick(View v) {
if(playClick%2==0){
song1.setBackgroundResource(R.drawable.button_pause);
try{
if(playClick==0){
playThread();
if(lastPlayedExists){
lastPlayed.release();
}
}
mp.start();
mpExists = true;
playClick++;
lastPlayed = mp;
lastPlayedExists=true;
mp.setOnCompletionListener(new OnCompletionListener(){
#Override
public void onCompletion(MediaPlayer media) {
mp.reset();
song1.setBackgroundResource(R.drawable.button_play);
}
});
}catch (NullPointerException e){
}
}
else if (playClick%2==1){
song1.setBackgroundResource(R.drawable.button_play);
mp.pause();
playClick++;
}
}
}
});
And this is the thread for media player
private void playThread(){
try{
new Thread(new Runnable() {
public void run() {
try {
mp.setDataSource(song);
} catch (IllegalArgumentException 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();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
}catch(IllegalStateException e){
}
}
I have tried it with the onCompletion having mp.reset(), mp.stop(), and mp.release() along with trying lastPlayed.release() all in different tests. As well as none of them being there and it just being the button change and the progress bar reset. If you know how to fix this and make it replay as it should I would greatly appreciate it. Or if you know how to make the thread stop and restart some how so that I can just make it recall and do the thread over again that would work too (atm when that has been tried it crashes because the thread has already been started). Thanks and I appreciate any input.

mp.setOnCompletionListener(new OnCompletionListener(){
#Override
public void onCompletion(MediaPlayer media) {
playClick=2;
song1.setBackgroundResource(R.drawable.button_play);
}
});
