Broadcast Receiver für ACTION_MEDIA_BUTTON nicht gefeuert

Question

Ich entwickle und App, die Daten aus dem Internet streamen, habe ich Android MediaPlayer und AudioManager und alles funktioniert gut. Ich bin in ACTION_MEDIA_BUTTON steckengeblieben, um den Player über die Kopfhörer-Taste abzuspielen/anzuhalten.

FYI, habe ich den ganzen Weg in stackover, setPriority zu 999 oder 1000 oder 10000 auch Zuhörer registrieren in android menifeast Datei usw. aber nicht dazu führen, vorgeschlagen verwendet.

BroadcarstReceiver Datei

public class HeadSetReceiver erweitert BroadcastReceiver {

onHeadsetEventListener mCallback; 


    public interface onHeadsetEventListener { 
     void onHeadsetRemoved(); 

     void onHeadsetNextClicked(); 

     void onHeadsetPreviousClicked(); 

     void onHeadsetPlayPauseClicked(); 
    } 


    @Override 
    public void onReceive(Context context, Intent intent) { 

     mCallback = (onHeadsetEventListener) context; 


     // Intent.ACTION_HEADSET_PLUG << Trigger as soon i plug and unplug the headphone.. 

     if (intent.getAction().equals(Intent.ACTION_HEADSET_PLUG)) { 
      int state = intent.getIntExtra("state", -1); 
      switch (state) { 
       case 0: 
        mCallback.onHeadsetRemoved(); 
        break; 
       case 1: 
        break; 
      } 
     } 

     // Intent.ACTION_MEDIA_BUTTON ---- Not triggered even after register listener 
     if (intent.getAction().equals(Intent.ACTION_MEDIA_BUTTON)) { 
      KeyEvent event = (KeyEvent) intent 
        .getParcelableExtra(Intent.EXTRA_KEY_EVENT); 
      int keycode = event.getKeyCode(); 
      int action = event.getAction(); 
      Log.i("keycode", String.valueOf(keycode)); 
      Log.i("action", String.valueOf(action)); 
      //onKeyDown(keyCode, event) 
      if (keycode == KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE || keycode == KeyEvent.KEYCODE_HEADSETHOOK) 
       if (action == KeyEvent.ACTION_DOWN) 
        mCallback.onHeadsetPlayPauseClicked(); 
      if (keycode == KeyEvent.KEYCODE_MEDIA_NEXT) 
       if (action == KeyEvent.ACTION_DOWN) 
        mCallback.onHeadsetNextClicked(); 
      if (keycode == KeyEvent.KEYCODE_MEDIA_PREVIOUS) 
       if (action == KeyEvent.ACTION_DOWN) 
        mCallback.onHeadsetPreviousClicked(); 

     } 
    } 
} 

* I Zuhörer in MediaPlayerService.java registriert haben - OnCreate() als folgen *

headSetReceiver = new HeadSetReceiver(); 

IntentFilter filter2 = new IntentFilter(Intent.ACTION_MEDIA_BUTTON); 
filter2.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY); 
registerReceiver(playerRadioService.headSetReceiver,filter2); 

Und auch nicht registriert onDestroy als

unregisterReceiver(headSetReceiver); 

folgen, aber ich bin mir nicht sicher, zu implementieren und damit auf das kein Ergebnis gibt, was ich fehle.
