How to detect headset button click with Android Broadcast Receiver

I tried many codes on the stackoverflow.com

I can't receive any action from onReceiver method. When i receive any signal from onReceiver, I will add spesific if conditions into onReceiver for (long press etc.) But I cant even able to receive any signal from onReceiver.

What should I do for detecting headset button presses?

Headset means earphone(for phone), I hope I explained my issue Thanks in advance :)

Here is my codes: (Also added Bluetooth permission)

@Override  protected void onResume() {      super.onResume();        IntentFilter filter = new IntentFilter(Intent.ACTION_MEDIA_BUTTON);        registerReceiver(headsetBroadcastingClass,filter);    }  

Broadcast Receiver class:

public class HeadsetBroadcastingClass extends BroadcastReceiver {   public HeadsetBroadcastingClass() {       super();       System.out.println("initialized");   }     @Override   public void onReceive(Context context, Intent intent) {       Toast.makeText(context, "action detected", Toast.LENGTH_SHORT).show();   }  }  

And here is my manifest.xml:

 ....  </activity>        <service android:name=".MusicService" />      <receiver android:name=".HeadsetBroadcastingClass">          <intent-filter android:priority="999999999">              <action android:name="android.intent.action.MEDIA_BUTTON" />          </intent-filter>      </receiver>  </application>
