Android emulate/send ACTION_MEDIA_BUTTON intent

I am trying to control universal music playback (play/pause, skip etc.) by emulating headset music controls. Is there a way to broadcast the ACTION_MEDIA_BUTTON intent? I tried the regular way with sendBroadcast() but it didn't work.

Is this possible?

You can dispatch different KeyEvent.KEYCODE_MEDIA_* to AudioManager

AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audio.dispatchMediaKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, 
KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE));
audio.dispatchMediaKeyEvent(new KeyEvent(KeyEvent.ACTION_UP, 
KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE));

This will only work for apps that listen to these media events by calling

AudioManager.registerMediaButtonEventReceiver or MediaSession.setMediaButtonReceiver

Try this

  long eventtime = SystemClock.uptimeMillis(); 

  Intent downIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 
  KeyEvent downEvent = new KeyEvent(eventtime, eventtime, 
KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE, 0); 
  downIntent.putExtra(Intent.EXTRA_KEY_EVENT, downEvent); 
  sendOrderedBroadcast(downIntent, null); 

  Intent upIntent = new Intent(Intent.ACTION_MEDIA_BUTTON, null); 
  KeyEvent upEvent = new KeyEvent(eventtime, eventtime, 
KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE, 0); 
  upIntent.putExtra(Intent.EXTRA_KEY_EVENT, upEvent); 
  sendOrderedBroadcast(upIntent, null);
