我在Android應用程序中使用FirebaseMessaging進行即時消息傳遞。FirebaseMessaging Android有些消息丟失

對於從服務器到設備Android的消息,不會丟失消息。

但是從移動到服務器一些消息丟失...

服務器接收ACK消息,但在其他方向(移動到服務器)移動不接收ACK。

其結果是大約30%的消息丟失。如果我快速發送多條消息,會有更多的損失(40-60%)。如果我緩慢地發送多個消息,則有10%的消息丟失...

當我將消息發送到服務器時,我注意到在我的FirebaseMessagingService中,方法「onMessageSent」被10個消息模糊地調用。這是正常的嗎? 爲什麼 「onMessageSent」 不是一次,只要消息被髮送稱爲...

public class MyFirebaseMessagingService extends FirebaseMessagingService { 

private static final String TAG = "MyFirebaseMsgService"; 
/** constante pour renvoyer la position GPS */ 
public static final String BROADCAST_FIREBASE_FILTER= "android.intent.action.MY_APP_FIREBASE"; 

private DatabaseHelper helper; 

@Override 
public void onCreate() { 
    super.onCreate(); 
} 

/** 
* 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) { 
    Notification method below.  
    DebugLog.logw(TAG,"MESSAGE RECEIVED"); 
    String clickAction = remoteMessage.getNotification().getClickAction();   
    [..] 

} 
// [END receive_message] 

/** 
* Create and show a simple notification containing the received FCM message. 
* 
* @param messageBody FCM message body received. 
*/ 
private void sendNotification(String title, String messageBody,Intent intent2) { 

    intent2.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent2, 
      PendingIntent.FLAG_ONE_SHOT); 

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
      .setSmallIcon(R.mipmap.ic_launcher) 
      .setContentTitle(title) 
      .setContentText(messageBody) 
      .setAutoCancel(true) 
      .setSound(defaultSoundUri) 
      .setContentIntent(pendingIntent); 

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

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

} 

@Override 
public void onDeletedMessages() { 
    super.onDeletedMessages(); 
    DebugLog.logi(TAG, "onDeletedMessages"); 
} 

@Override 
public void onMessageSent(String s) { 
    super.onMessageSent(s); 
    DebugLog.logi(TAG, "onMessageSent = " + s); 
} 

@Override 
public void onSendError(String s, Exception e) { 
    super.onSendError(s, e); 
    DebugLog.logi(TAG, "onSendError = " + s); 
} 

}

我在我的FragmentMessaging方法發送消息:

public void sendMessage(Message msg){ 
    DebugLog.logd("FragmentMessagerie","sendMessage msg = " + msg.getMsg()); 
    if(textMessage.getText().length()>0) { 
     final Message message = msg;   

     AtomicInteger atomicInteger = new AtomicInteger(); 
     FirebaseMessaging fm = FirebaseMessaging.getInstance(); 

     RemoteMessage rm = new RemoteMessage.Builder(senderID) 
       .setMessageId("myApp_" + atomicInteger.incrementAndGet() + System.currentTimeMillis()) 
       .addData("action", "chat") 
       .addData("destinataire", String.valueOf(contact.getId())) 
       .addData("emetteur",username) 
       .addData("texte",msg.getMsg()) 
       .setTtl(0) 
       .build();      
     fm.send(rm); // appel à fireBase pour l'envoi du message 
     [..] 

     textMessage.setText(""); 
    } else { 
     [..] 
    } 
} 

}

我的問題是:

當發送消息(firebaseMessaging.send(remoteMessage))Firebase應該處理向服務器發送消息。

Android是否將消息錯誤地發送到Firebase?

還是Firebase將消息嚴重地發送到我的服務器?

在服務器上,我收到發送給手機的ACK消息。

在我的設備Android上,我沒有收到ACK消息,當發送10條消息時,只有方法「onMessageSent」被調用了10次......這是正常的嗎?

如何才能收到ACK消息設備Android到服務器?從我的設備?

在此先感謝您的幫助!

它清楚地在FCM documentation中說,響應是成批的。

爲了優化網絡使用率,FCM批次響應onMessageSent和 onSendError,因此確認可以不會立即對每條消息。
