Getting a error with Firebase Cloud Messaging

Question

I'm just starting with Firebase and I was trying with a kind of complex code that I saw on a tutorial, and I get an error, so I just copied a simple code, very basic, but I'm still getting the same error, please help me, I'm gonna put the FirebaseInstanceIdService and the FirebaseMessagingService, but if you need further information please let me know.

The error that I'm getting

FirebaseMessagingService

public class MiFirebaseMessagingService extends FirebaseMessagingService {

public static final String TAG = "SERVICIOS";


@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    String from = remoteMessage.getFrom();
    Log.d(TAG, "Mensaje recibido de " + from);

    if(remoteMessage.getNotification() != null){
        Log.d(TAG, "Notificacion" + remoteMessage.getNotification().getBody());
        mostrarNotificacion(remoteMessage.getNotification().getTitle(), remoteMessage.getNotification().getBody());
    }

    if(remoteMessage.getData().size() > 0 ){
        Log.d(TAG, "Data: " + remoteMessage.getData());
    }

}

private void mostrarNotificacion(String title, String body) {

    Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Intent intent = new Intent(this, Activity_Metodos_de_Pago.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);

    NotificationCompat.Builder notificationBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.builder)
            .setContentTitle(title)
            .setContentText(body)
            .setAutoCancel(true)
            .setSound(soundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notificationBuilder.build());
    }
}

FirebaseInstanceIdService

public class MiFirebaseInstanceIdService extends FirebaseInstanceIdService {
@Override
public void onTokenRefresh() {
    super.onTokenRefresh();

    String token = FirebaseInstanceId.getInstance().getToken();

    Log.d(TAG, "Token: " + token);

    enviarTokenAlServidor(token);
}
private void enviarTokenAlServidor(String token) {
    }
}

Thanks.
