Handle Media Button from Service in Android 8.0+?

Question

i'm trying to handle the headsethook from a service in Android to start an action for my app, using MediaSessionCompat class, that it's different from the Media Player purpose.

Now, i wrote this code that work in Android 7 and below, but not with Android 8.0 and over and i don't know why.

ComponentName componentName = new ComponentName(getApplicationContext(), MediaButtonReceiver.class);
final Intent mediaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON);
mediaButtonIntent.setComponent(componentName);

PendingIntent mediaButtonReceiverPendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, mediaButtonIntent, 0);

MediaSessionCompat mediaSessionCompat = new MediaSessionCompat(getApplicationContext(), getPackageName());
mediaSessionCompat.setCallback(new MediaSessionCompat.Callback()
    {
        @Override
        public boolean onMediaButtonEvent(Intent mediaButtonEvent)
        {

            KeyEvent keyEvent =
                    (KeyEvent) mediaButtonIntent.getExtras().get(Intent.EXTRA_KEY_EVENT);
            if (keyEvent.getAction() == KeyEvent.ACTION_DOWN)
            {
                if (keyEvent.getKeyCode() == KeyEvent.KEYCODE_HEADSETHOOK)
                {
                    Log.d(TAG, STRING_EXAMPLE);
                    return true;
                }
            }

            return super.onMediaButtonEvent(mediaButtonEvent);
        }
    });

    mediaSessionCompat.setActive(true);

    mediaSessionCompat.setFlags(MediaSessionCompat.FLAG_HANDLES_MEDIA_BUTTONS | MediaSessionCompat.FLAG_HANDLES_TRANSPORT_CONTROLS);
    mediaSessionCompat.setMediaButtonReceiver(mediaButtonReceiverPendingIntent);

I tried to put this code into OnStart() of the MainActivity and into onStartCommand of my serivce but nothing happened.

I tried also leave this in my manifest, but doesn't work.

<receiver android:name=".MediaButtonServiceListener">
        <intent-filter>
            <action android:name="android.intent.action.MEDIA_BUTTON" />
        </intent-filter>
    </receiver>

I leave my Receiver and my Service, maybe i wronged somewhere or anyone can help me to understand why doesn't work, unfortunately Android's doc its useless for this thing.

Receiver:

public class MediaButtonServiceListener extends MediaButtonReceiver {

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

    Log.d(TAG, STRING_EXAMPLE);
    }
}

Service:

public class ExampleService extends Service {

@Override
public void onCreate() {
    super.onCreate();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId)
{
    Intent notificationIntent = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

    Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
            .setContentTitle("Example Service")
            .setContentText("Service in foregound")
            .setSmallIcon(R.drawable.ic_android)
            .setContentIntent(pendingIntent)
            .build();

    startForeground(1, notification);

    return START_NOT_STICKY;
}

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public void onDestroy() {
    super.onDestroy();
}
