Hi all,
I am developing an application, where i need to capture the timestamp of
music starts and ends. For that have used OnAudioFocusChangeListener, and
request for AUDIO_GAIN event. Below is my code.
public class AudioManagerExample extends Activity implements
OnAudioFocusChangeListener{
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
AudioManager am = (AudioManager) getSystemService(AUDIO_SERVICE);
int result = am.requestAudioFocus(this,AudioManager.STREAM_MUSIC
,AudioManager.AUDIOFOCUS_GAIN);
if(result == AudioManager.AUDIOFOCUS_REQUEST_GRANTED)
Log.d("AudioManager", "Request Granted");
}
@Override
public void onAudioFocusChange(int focusChange) {
if(focusChange == AudioManager.AUDIOFOCUS_GAIN)
Log.d("AudioManager", "Inside on audio focus gained " );
else if(focusChange == AudioManager.AUDIOFOCUS_LOSS)
Log.d("AudioManager", "Inside on audio focus lossed ");
}
}
onAudioFocusChange function get called when i play the music, am getting
"audio focus lossed" message instead of gain message and I checked the
focusChange value it is -1. Also listener will be called only once i.e when
i opened the music first time. Listener is not called If music player is
closed and opened again. Why is this so? Do i need to add any permission?
I had surfed a lot but not get the proper solution Please anybody could
explain?
Thanks
Pushpa
