Question

<receiver android:name=".MusicIntentReceiver" android:exported="false">
            <intent-filter>
                <action android:name="android.media.AUDIO_BECOMING_NOISY" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.MEDIA_BUTTON" />
            </intent-filter>
        </receiver>

This is detail MusicIntentReceiver ... public class MusicIntentReceiver extends BroadcastReceiver { private static final String TAG = LogHelper.makeLogTag(MusicIntentReceiver.class);

    @Override
    public void onReceive(Context context, Intent intent) {
        //LogHelper.i(TAG, "-------------------------------- MusicIntentReceiver.");
        if (intent.getAction().equals(android.media.AudioManager.ACTION_AUDIO_BECOMING_NOISY)) {
            LogHelper.d(TAG, "Headphones disconnected.");
            // send an intent to our MusicService to telling it to pause the audio
            try {
                //TODO Something
            }
            catch (Exception e) {
                //LogHelper.i(TAG, "MusicIntentReceiver onReceive ", e.getMessage());
            }
        }
        else {
            if (!MainActivity.getInstance().isSDK50orGreater()) {
                if (intent.getAction().equals(Intent.ACTION_MEDIA_BUTTON)) {
                    KeyEvent keyEvent = (KeyEvent) intent.getExtras().get(Intent.EXTRA_KEY_EVENT);
                    if (keyEvent.getAction() != KeyEvent.ACTION_DOWN)
                        return;
                    //LogHelper.i(TAG, "---------------------------- onReceive ", keyEvent.getKeyCode());
                    switch (keyEvent.getKeyCode()) {
                        case KeyEvent.KEYCODE_HEADSETHOOK:
                        case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:
                            context.startService(new Intent(MediaContant.ACTION_TOGGLE_PLAYBACK));
                            break;
                        case KeyEvent.KEYCODE_MEDIA_PLAY:

                            context.startService(new Intent(MediaContant.ACTION_STOP));
                            break;

                            break;
                        case KeyEvent.KEYCODE_MEDIA_PREVIOUS:
                            // previous song
                            context.startService(new Intent(MediaContant.ACTION_PREVIOUS));

Answer 1

I use mMediaButtonReceiverComponent = new ComponentName(this, MusicIntentReceiver.class); mAudioManager.registerMediaButtonEventReceiver(mMediaButtonReceiverComponent);

Intent mediaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON); mediaButtonIntent .setComponent(mMediaButtonReceiverComponent); mRemoteControlClientCompat = new RemoteControlClient(PendingIntent.getBroadcast(getApplicationContext() /context/, 0 /requestCode, ignored/, mediaButtonIntent /intent/, 0 /flags/)); mAudioManager.registerRemoteControlClient(mRemoteControlClientCompat);

Cannot control remote control for android 4.4.2

If you want your app to keep on working when the screen is off, you'll need to acquire a PARTIAL_WAKE_LOCK

Be careful, there is a reason those buttons don't work when the screen is off, it's to conserve battery. You'll have to be extremely careful your application doesn't drain the phone battery.
