Java Android FirebaseMessagingService：onMessageReceivedがまったく呼び出されない

Question

FirebaseMessagingService Javaクラスに問題があります。 Firebaseコンソールから通知を送信すると、onMessageReceived関数はまったく呼び出されません。私は唯一のコンソールで取得

package com.nufdev.firelink.other; 

import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Context; 
import android.content.Intent; 
import android.media.RingtoneManager; 
import android.net.Uri; 
import android.support.v4.app.NotificationCompat; 
import android.util.Log; 

import com.google.firebase.messaging.FirebaseMessagingService; 
import com.google.firebase.messaging.RemoteMessage; 
import com.nufdev.firelink.MainActivity; 
import com.nufdev.firelink.R; 

public class MyFirebaseMessagingService extends FirebaseMessagingService { 
    private static final String TAG = "MyFirebaseMsgService"; 

    /** 
    * Called when message is received. 
    * 
    * @param remoteMessage Object representing the message received from Firebase Cloud Messaging. 
    */ 
    // [START receive_message] 
    @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()); 
     } 

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

    /** 
    * Create and show a simple notification containing the received FCM message. 
    * 
    * @param messageBody FCM message body received. 
    */ 
    private void sendNotification(String messageBody) { 
     Intent intent = new Intent(this, MainActivity.class); 
     intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent, 
       PendingIntent.FLAG_ONE_SHOT); 

     Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
     NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
       .setSmallIcon(R.drawable.icon_send) 
       .setContentTitle("FCM Message") 
       .setContentText(messageBody) 
       .setAutoCancel(true) 
       .setSound(defaultSoundUri) 
       .setContentIntent(pendingIntent); 

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

     notificationManager.notify(0 /* ID of notification */, notificationBuilder.build()); 
    } 

    @Override 
    protected Intent zzaa(Intent intent) { 
     Log.v(TAG, "ZZZA?"); 
     return null; 
    } 
} 

私はFirebaseコンソールからの通知を送信するたびに：ZZAAしかし、私は成功した通知が送信され、ここに私のコードは知っていますか？これのために：

@Override 
     protected Intent zzaa(Intent intent) { 
      Log.v(TAG, "ZZZA?"); 
      return null; 
     } 

私は何zzaa手段見当がつかないし、Googleでそれを見つけることができません。
もしあなたが私を助けることができたら、それは素晴らしいだろう。 ：たぶん、あなたは（guideから取られた）マニフェスト

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

Answer 1

D FCMは、通知メッセージの2種類がありそうです。 FCMコンソールは常に「通知メッセージ」を送信します。この通知メッセージは、アプリケーションがフォアグラウンドの場合にのみonMessageReceivedをトリガーします。コンセプトについて 詳細：FCMのクイックスタートのサンプルコードでhttps://firebase.google.com/docs/cloud-messaging/concept-options

説明：

// [START receive_message] 
@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
    // [START_EXCLUDE] 
    // There are two types of messages data messages and notification messages. Data messages are handled 
    // here in onMessageReceived whether the app is in the foreground or background. Data messages are the type 
    // traditionally used with GCM. Notification messages are only received here in onMessageReceived when the app 
    // is in the foreground. When the app is in the background an automatically generated notification is displayed. 
    // When the user taps on the notification they are returned to the app. Messages containing both notification 
    // and data payloads are treated as notification messages. The Firebase console always sends notification 
    // messages. For more see: https://firebase.google.com/docs/cloud-messaging/concept-options 
    // [END_EXCLUDE] 

    // TODO(developer): Handle FCM messages here. 
    // Not getting messages here? See why this may be: https://firebase.google.com/support/faq/#fcm-android-background 
    Log.d(TAG, "From: " + remoteMessage.getFrom());
