I have an activity with a media player as a member variable.
My media player is initialized like this:
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setDataSource(MyActivity.this, URL);
mMediaPlayer.prepareAsync();
//i set a on Prepared Listener to start playing on Prepared
Everything works just fine, and then i override my activity onStop method to release the Media Player.
if(mMediaPlayer!=null){
if(mMediaPlayer.isPlaying()){
mMediaPlayer.stop();
}
mMediaPlayer.release();
mMediaPlayer=null;
}
But after the activity has stopped i get a memory leak report from LeakCanary.
The report is like this:
MyApp.Instance->
MyApp.mLoadedApk->
LoadedApk.mReceivers->
ArrayMap.mArray->
arrayObject[].[3]->
ArrayMap.mArray->
arrayObject[][0]->
MediaPlayer.mProxyReceiver->
MediaPlayer.mProxyContext->
leaks MyActivity instance.
MyApp.Instance->
MyApp.mLoadedApk->
LoadedApk.mReceivers->
ArrayMap.mArray->
arrayObject[].[3]->
ArrayMap.mArray->
arrayObject[][0]->
MediaPlayer.mProxyReceiver->
MediaPlayer.mProxyContext->
leaks MyActivity instance.
Yes i have a MyApp class which extends Application and i am holding a reference to MyApp instance in a static field, but i never use that reference in my activity, how can i solve this leak ?
[EDIT]
Here is the code of my Activity:
public class PlayActivity extends ActionBarActivity {
private MediaPlayer mediaPlayer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_play);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
protected void onStop() {
super.onStop();
if(mediaPlayer!=null){
if(mediaPlayer.isPlaying()){
mediaPlayer.stop();
}
mediaPlayer.release();
mediaPlayer=null;
}
}
public void playIt(View view){
if(mediaPlayer==null){
mediaPlayer = new MediaPlayer();
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
}
if(!mediaPlayer.isPlaying()){
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
mediaPlayer.setDataSource(PlayActivity.this, Uri.parse("http://www.noiseaddicts.com/samples_1w72b820/142.mp3"));
mediaPlayer.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
