不工作 notificactioncompat 与 firebase

Question

我不知道，但我的通知没有显示.. 只能看到带有 Log Consola Android Studio 的消息 u.u

public class MyFcmListenerService extends com.google.firebase.messaging.FirebaseMessagingService {
public static final String TAG = MyFcmListenerService.class.getSimpleName();

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    Log.d(TAG,"HECHO");
    Log.d(TAG,remoteMessage.getData().get("message"));
    Log.d(TAG, "token_test_"+Test.getTest(1).getToken_test());
    if (Test.getTest(1).isEstado_token()) {
        Log.d(TAG,"bolean1"+String.valueOf(Test.getTest(1).isEstado_token()));
        mostrarMensaje(remoteMessage.getData().get("message"));
    }
}

private void mostrarMensaje(String mensaje) {
    SharedPreferences preferences = getSharedPreferences(Constantes.PREFERENCIA_PARA_PREGUNTAS, Context.MODE_PRIVATE);
    int pre_token_count = preferences.getInt(Constantes.KEY_IDENTIFICADOR, 0);

    Intent i = new Intent(this, PrincipalActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_ONE_SHOT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("TEST")
            .setContentText(mensaje)
            .setContentIntent(pendingIntent)
            .setPriority(NotificationCompat.PRIORITY_HIGH)
            .setVibrate(new long[]{2000, 2000, 2000, 2000, 2000});

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    manager.notify(pre_token_count, builder.build());

    SharedPreferences.Editor editor = preferences.edit();
    pre_token_count++;
    editor.putInt(Constantes.KEY_IDENTIFICADOR, pre_token_count);
    editor.commit();

}

}

documentation表示通知需要有图标：

A Notification object must contain the following:

• A small icon, set by setSmallIcon()
• A title, set by setContentTitle()
• Detail text, set by setContentText()

使用 setSmallIcon() 在您的通知中添加一个图标。
