FCM onMessageReceived未调用Android

问题描述

在Android应用程序中实施FCM时遇到一个问题.

I am facing one problem while implementing FCM in Android application.

一切正常，我的服务onMessageReceived()没有通话.但是，当我从Java服务器发送消息时，正在跟踪日志.

Everything works fine, my service onMessageReceived() is not calling. But I am getting following logs when I send a message from my Java Server.

有什么建议吗??

这是我的服务课程，

class MyFirebaseMessagingService : FirebaseMessagingService() {
    internal var TAG = "FCM Message"
    override fun onMessageReceived(remoteMessage: RemoteMessage?) {
        Log.e(TAG, "From: " + remoteMessage!!.getFrom())

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

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

AndroidManifest.xml文件，

AndroidManifest.xml file,

<service android:name=".fcm.MyFirebaseInstanceIDService"
        android:exported="false">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
    </intent-filter>
</service>

<service android:name=".fcm.MyFirebaseMessagingService"
    android:exported="false">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>

我在后台运行时收到通知.如果应用程序出现在前台，则会发生问题

推荐答案

当您的应用程序在后台或被终止时，Firebase不会调用您的onMessageReceived()，并且您无法自定义通知.它将显示由Firebase自己管理的通知.

Firebase will not call your onMessageReceived() when your app is in the background or killed, and you can't customise your notification. It will show notifications managed by Firebase it self.

使Firebase库在任何情况下都可以调用您的onMessageReceived()

to make Firebase library to call your onMessageReceived() in every case

b)背景

c)被杀死

请勿在对Firebase API的请求中放入JSON密钥"notification"，而应使用"data" ，请参见下文.

例如，以下消息不会调用onMessageReceived()

For example, following message will not call onMessageReceived()

{
  "to": "/topics/test",
  "notification": {
    "title" : "title",
    "message": "data!"
   }
}

但这会起作用

{
  "to": "/topics/test",
   "data": {
       "title":"title",
       "message":"data!"
   }
}

请参阅此文档，其中详细说明了Firebase消息类型，例如:

see this it has a detailed description of firebase message type For example:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.d(TAG, "From: " + remoteMessage.getFrom());

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

private void sendNotification(String message, String title) {
    int requestID = (int) System.currentTimeMillis();
    Intent intent = new Intent(this, activityCompat);

    PendingIntent pendingIntent = PendingIntent.getActivity(this, requestID, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.small_logo)
            .setContentTitle(title)
            .setContentText(message).setContentIntent(pendingIntent)
            .setAutoCancel(true)
            .setStyle(new NotificationCompat.BigTextStyle()
                    .bigText(messageBody))
            .setTicker(messageBody);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
    Notification notification = notificationBuilder.build();

    notificationManager.notify(requestID, notification);
}
