I have 2 activities and a static mediaplayer in my first activity I prepare and start the media player and jump to other activity. In the second activity I can pause and play this media player when I press back button on the second activity it goes to the first activity and than stop media player and than release media player but mp.release gives me "has stopped unexpectedly error". Can you help me please? I need to make this mp.release() work
new AsyncTask<Void, Double, Void>() {
@Override
protected Void doInBackground(Void... params) {
while (true) {
publishProgress(Math.random());
SystemClock.sleep(3000);
if(isOnline(Start.this) == true && connection == true){
LinkedList<String> urls = readM3UtoUrlList("url.m3u");
mp = new MediaPlayer();
try {
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.setDataSource(urls.getFirst());
mp.setOnPreparedListener(new OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
Intent i = new Intent(Start.this, RadyoBabylonActivity.class);
startActivityForResult(i, RadyoBabylonActivity.class.hashCode());
}
});
mp.prepare();
mp.start();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
@Override
protected void onProgressUpdate(Double... values) {
}
}
}.execute();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode==-1){
Log.d("myerror", "kapanacavk");
mp.stop();
if(!mp.isPlaying())
{
mp.release();
finish();
}
}
}
