Ниже приведены зависимости в Gradle сборки приложения 

implementation 'com.google.firebase:firebase-messaging:20.0.1'
implementation "android.arch.work:work-runtime:1.0.1"

Ниже приведен класс FirebaseMessagingService 

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    @Override
    public void onNewToken(@NonNull String s) {
        super.onNewToken(s);
        Log.v("## onNewToken", "## onNewToken : "+s);
        //Toast.makeText(getApplicationContext(), "onNewToken : "+s, Toast.LENGTH_LONG).show();
    }


    @Override
    public void onMessageReceived(final RemoteMessage remoteMessage) {
        Log.v("## onMessageRecived CLD", "## onMessageReceived Called");

        Log.v("## onMessageRecivedData", "## onMessageReceived Data: "+remoteMessage.getData());


        Handler handler = new Handler(Looper.getMainLooper());
        handler.post(new Runnable() {
            public void run() {
                Toast.makeText(getApplicationContext(), "onMessagedReceived Called", Toast.LENGTH_LONG).show();
            }
        });

        PeriodicWorkRequest periodicWorkRequest = null;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            periodicWorkRequest = new PeriodicWorkRequest.Builder(MyWorker.class, 15, TimeUnit.MINUTES)
                    .setConstraints(new Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build())
                    .build();
        }
        WorkManager.getInstance().enqueueUniquePeriodicWork("SyncWorker", ExistingPeriodicWorkPolicy.KEEP, periodicWorkRequest);


    }
}

Ниже приведено исключение, которое возникает, когда onMessageReceivedCalled () в Android 6.0 (Marshmallow):

Я получаю исключение выше, когда onMessageReceived () вызывается в Android 6.0. Пожалуйста, помогите мне в этом. Заранее спасибо
