【英文标题】：Android - FCM Push Notification not received after click_action is included

【问题描述】：

我正在开发一个 android 应用程序，我希望在应用程序状态同时处于前台和后台时接收推送通知。

在添加 click_action 之前它工作正常，但在添加它之后，当应用程序处于后台或被终止时，它不会收到推送通知。经过一番研究，我可以理解如果 FCM 是“通知”消息类型而只有“数据”消息类型，我将无法在后台接收推送。

由于FCM默认提供click_action属性，并且在onMessageReceived()中也提供了getClickAction()的方法来获取它，我真的应该在数据消息中使用click_action吗？

onMessageReceived中处理方式的代码sn-p

 @Override
    public void onMessageReceived(RemoteMessage remoteMessage) 
        ......
        ......
        showNotification(remoteMessage);
    



public void showNotification(RemoteMessage remoteMessage) 

        try 
            Map<String, String> response = remoteMessage.getData();

            Intent intent = prepareIntent(remoteMessage);
            PendingIntent pIntent = PendingIntent.getActivity(this, 0,
                    intent, PendingIntent.FLAG_ONE_SHOT);
            NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "D4E_ANDROID")
                    .setContentTitle("New Notification")
                    .setContentText(response.get("notification"))
                    .setSmallIcon(R.drawable.d4e_logo)
                    .setContentIntent(pIntent)
                    .setAutoCancel(true)
                    .addAction(R.drawable.view_icon, "View", pIntent);

            NotificationManager notificationManager =
                    (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

            notificationManager.notify(Integer.parseInt(response.get("notificationId")), builder.build());
         catch (Exception exception) 
            Log.e("OnREC", exception.toString());
        

    


 public Intent prepareIntent(RemoteMessage remoteMessage) 
        Map<String, String> response = remoteMessage.getData();
        Intent intent;
        boolean isAppInBackground;
        if (SessionContext.isLoggedIn()) 
          isAppInBackground = SessionHelper.initializeSessionHelper().isAppInBackground(this);
                Log.e("LOGGGGG", isAppInBackground + "");
                if (isAppInBackground) 
                    intent = new Intent(this, SplashScreen.class);
                 else 
                    intent = new Intent(remoteMessage.getNotification().getClickAction());
                
            
         else 
            intent = new Intent(this, LoginActivity.class);
        


        return intent;
    

请任何人指导我找到解决方案。

【问题讨论】：

你的后端有问题..你的 android 部分看起来很不错

@Santanu 你能根据我分享的捆绑包指导我吗？在后端需要改变什么？

【参考方案1】：

如果您可以接收到通过控制台发送的 FCM 通知，那么构建通知可能有问题。一个怀疑是您没有使用“图标”字段。 如果您可以调试 android 设备，请在此处设置断点并查看是否出现错误或错过了某些资源。 https://github.com/evollu/react-native-fcm/blob/master/android/src/main/java/com/evollu/react/fcm/SendNotificationTask.java#L46

【讨论】：

应用在后台时日志也没有打印，但在前台状态下打印

看这个：pluralsight.com/guides/android/…

从 Firebase 通知控制台发送的消息被视为仅通知消息有效负载（除非您添加自定义键值对，否则它将成为通知和数据）。仅通知消息负载行为是当应用程序处于后台时，Android 系统将处理通知。有关该行为的更多详细信息，请参阅 Android 版 firebase.google.com/docs/cloud-messaging/android/…。
