Java – If I press the headset button once, the android.intent.action.MEDIA_BUTTON event fires twice

I’ve written a piece of code to display the toast when the headphone media button is pressed. I used an intent filter to get it done. But the problem is that it triggers twice when I press the media button.
My code is:

MainActivity.java

private MusicIntentReceiver myReceiver;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

myReceiver=new MusicIntentReceiver();

((AudioManager)getSystemService(AUDIO_SERVICE)).registerMediaButtonEventReceiver(new ComponentName(
            this,
            MusicIntentReceiver.class));
}

@Override
public void onResume(){
    IntentFilter filter = new IntentFilter(Intent.ACTION_HEADSET_PLUG);
    IntentFilter filter1=new IntentFilter(Intent.ACTION_MEDIA_BUTTON);
    filter1.setPriority(100);
    registerReceiver(myReceiver, filter);
    registerReceiver(myReceiver,filter1);
    super.onResume();
}

@Override
public void onPause() {
    IntentFilter filter = new IntentFilter(Intent.ACTION_HEADSET_PLUG);
    IntentFilter filter1=new IntentFilter(Intent.ACTION_MEDIA_BUTTON);
    filter1.setPriority(100);
    registerReceiver(myReceiver, filter);
    registerReceiver(myReceiver,filter1);
    super.onPause();
}

BroadcastReceiver.java

public class MusicIntentReceiver extends BroadcastReceiver {

@Override
    public void onReceive(Context context, Intent intent) {
        String intentAction=intent.getAction();
        Toast.makeText(context, "Action: "+intentAction, Toast.LENGTH_SHORT).show();
        if (! Intent.ACTION_MEDIA_BUTTON.equals(intentAction)) {
            return;
        }
        Toast.makeText(context, "BUTTON PRESSED!", Toast.LENGTH_SHORT).show();
        abortBroadcast();
    }
}

Press the button once

, press the button once.

  KeyEvent keyEvent  = (KeyEvent)intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
  if (keyEvent != null) {
      if (event.getAction() == KeyEvent.ACTION_UP)
      {
           switch(keyEvent.getKeyCode()) {
           case KeyEvent.KEYCODE_MEDIA_PLAY:
                  .... &c.
            }
      }
    }
