如何修复Firebase通知

Question

我已经正确地实现了Fire基础通知，一些设备没有接收到内部通知，在运行后台时会聚焦如何解决该问题

 public void getNotification(String icon,String title,String body){
      remoteViews = new RemoteViews(getPackageName(),R.layout.custom_notification_big);
      remoteView  = new RemoteViews(getPackageName(),R.layout.custom_notification_small);
      //Bitmap bitmap = SetImage(remote.getIcon()) ;
      Intent intent = new Intent(this, MainActivity.class);
      intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
      PendingIntent pendingIntent = PendingIntent.getActivity(this, 1410, intent, PendingIntent.FLAG_ONE_SHOT);
      NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
      if(icon!=null && !icon.isEmpty()){
        remoteViews.setImageViewBitmap(R.id.image_pic,bitmap);
      }else{

      }
      if(title != null && !title.isEmpty()){
          remoteViews.setTextViewText(R.id.title,title);
      }
      if(body != null && !body.isEmpty()){
          remoteViews.setTextViewText(R.id.text,body);
      }
      NotificationCompat.Builder notificationBuilder1 = new NotificationCompat.Builder(getApplicationContext())
              .setStyle(new NotificationCompat.DecoratedCustomViewStyle())
              .setCustomContentView(remoteView)
              .setCustomBigContentView(remoteViews)
              .setContentTitle("Notification")
              .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
              .setContentIntent(pendingIntent)
              .setAutoCancel(true)
              .setPriority(Notification.PRIORITY_MAX)
              .setDefaults(Notification.DEFAULT_VIBRATE);

      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
      {
          notificationBuilder1.setSmallIcon(R.mipmap.ic_launcher);
      } else
      {
          notificationBuilder1.setSmallIcon(R.mipmap.ic_launcher);

      }
      notificationManager.notify(100, notificationBuilder1.build());

  }

Answer 1

您需要为此添加频道

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            notificationManager.createNotificationChannel(
                NotificationChannel(
                    "YOUR_ID",
                    "YOUR_NAME",
                    NotificationManager.IMPORTANCE_HIGH
                )
            )
        }

Answer 2

没有收到通知！

在以下情况下使firebase调用onMessageReceived（）

1）应用程序在前台2）应用程序在后台3）应用程序已被杀死

您不能将JSON密钥“通知”放入您的请求/ InApp到firebase API，而是使用“数据”。

你可以按照文档。 https://firebase.google.com/docs/cloud-messaging/concept-options#notifications
