FCM - 在onMessageReceived中设置徽章

Question

我有一个Android应用程序,我正在使用一些方法在应用程序图标上显示通知编号.现在我想在收到通知时设置该号码.

我认为我应该在收到通知时设置数字,所以我在onMessageReceived方法中设置它.但是,我的问题是当我的应用程序处于后台时,onMessageReceived方法未被调用,因此未设置通知编号.

以下是我的代码.我在里面设置了号码onMessageReceived.我已经测试过setBadge方法并且可以验证它是否正常工作.问题是onMessageReceived没有调用所以setBadge也没有调用,没有设置数字.

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    // TODO(developer): Handle FCM messages here.
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Conts.notificationCounter ++;
    //I am setting in here.
    setBadge(getApplicationContext(),Conts.notificationCounter  );
    Log.e("notificationNUmber",":"+ Conts.notificationCounter);

    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {
        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
    }

    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {
        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
    }

    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated. See sendNotification method below.
}
// [END receive_message]



public static void setBadge(Context context, int count) {
    String launcherClassName = getLauncherClassName(context);
    if (launcherClassName == null) {
        Log.e("classname","null");
        return;
    }
    Intent intent = new Intent("android.intent.action.BADGE_COUNT_UPDATE");
    intent.putExtra("badge_count", count);
    intent.putExtra("badge_count_package_name", context.getPackageName());
    intent.putExtra("badge_count_class_name", launcherClassName);
    context.sendBroadcast(intent);
}

public static String getLauncherClassName(Context context) {

    PackageManager pm = context.getPackageManager();

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.addCategory(Intent.CATEGORY_LAUNCHER);

    List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, 0);
    for (ResolveInfo resolveInfo : resolveInfos) {
        String pkgName = resolveInfo.activityInfo.applicationInfo.packageName;
        if (pkgName.equalsIgnoreCase(context.getPackageName())) {
            String className = resolveInfo.activityInfo.name;
            return className;
        }
    }
    return null;
}

当我搜索这个问题时,我发现如果即将发出的消息是显示消息,那么onMessageReceived只有当app是前景时才会调用它.但是,如果即将发送消息是数据消息,则onMessageReceived即使应用程序是后台也会调用.

但是我的朋友告诉我发送通知的人(服务器端),消息已经同时显示和数据消息.他说数据对象已经填满了.

以下是JSON用于未来的消息,它的数据对象.

{  
   "to":"my_device_id",
   "priority":"high",

   "notification":{  
      "body":"Notification Body",
      "title":"Notification Title",
      "icon":"myicon",
      "sound":"default"
   },

   "data":{  
      "Nick":"DataNick",
      "Room":"DataRoom"
   }
}

如果我只使用数据对象,则按照他们的说法调用onMessageReceived,但该时间通知不会出现在顶部.

现在,onMessageReceived如果消息也是数据消息,为什么不调用.我应该做些不同的事情来处理数据信息吗？它是否与客户端的显示消息相同.

任何帮助,将不胜感激.提前致谢.

没有办法调用onMessageReceived,除非即将到来的json 仅包含数据有效负载,这是我从Firebase支持中学到的.

所以我必须使用数据有效负载,但如果您使用数据有效负载,它不会在顶部显示通知,因此您应该使用数据有效负载信息创建自定义通知.

因此,当我在onMessageReceived中获取数据有效负载时,我向自己发送了通知.我在向自己发送通知后立即在onMessageReceived中设置徽章.

以下代码是最终版本.

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    //for data payload
    // Check if message contains a data payload.
    if (remoteMessage.getData().size() > 0) {

        Log.d(TAG, "Message data payload: " + remoteMessage.getData());
        title = remoteMessage.getData().get("title");
        sendNotification(remoteMessage.getData().get("body"), title);
        badge = Integer.parseInt(remoteMessage.getData().get("badge"));
        Log.e("notificationNUmber",":"+badge);
        setBadge(getApplicationContext(), badge);

    }
    //for notification payload so I did not use here
    // Check if message contains a notification payload.
    if (remoteMessage.getNotification() != null) {

        Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());

    }

    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated. See sendNotification method below.
}
// [END receive_message]

private void sendNotification(String messageBody, String title) {
    Intent intent = new Intent(this, MainMenuActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, notify_no /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);
    if (notify_no < 9) {
        notify_no = notify_no + 1;
    } else {
        notify_no = 0;
    }
    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher_3_web)
            .setContentTitle(title)
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    notificationManager.notify(notify_no + 2 /* ID of notification */, notificationBuilder.build());
}

谢谢大家.
