media player should stop on disconnecting headphone in my android app programatically

问题

I have an issue in developing a media player application.
I want it so that when I remove my headphone from my device then the MediaPlayer in my app pauses.

The Android documentation suggests using the AUDIO_BECOMING_NOISY intent filter

Set the intent filter in your manafest and then:

public class MusicIntentReceiver extends android.content.BroadcastReceiver {
   @Override 
   public void onReceive(Context ctx, Intent intent) {
      if (intent.getAction().equals(
                    android.media.AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {
          // signal your service to stop playback 
          // (via an Intent, for instance) 
      } 
   } 
}

You can get a ACTION_HEADSET_PLUG Intent over the Broadcast when ever someone Plugs a Headset in or out.

At the start of your App you can use AudioManager.isWiredHeadsetOn() to check if ther is a headset pluged in at the moment. (Dont forgget to add MODIFY_AUDIO_SETTINGS permission.)

private BroadcastReceiver mNoisyReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if( mMediaPlayer != null && mMediaPlayer.isPlaying() ) {
            mMediaPlayer.pause();
        }
    }
};

Handles headphones coming unplugged. cannot be done through a manifest receiver

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
       IntentFilter filter = new IntentFilter(AudioManager.ACTION_AUDIO_BECOMING_NOISY);
       registerReceiver(mNoisyReceiver, filter);
    }

UnRegister Receiver

@Override
public void onDestroy() {
    super.onDestroy();
    unregisterReceiver(mNoisyReceiver);
}
