Firebase通知和数据

Question

我正在使用Firebase云消息传递API创建应用程序...我能够将通知和数据从服务器发送到我的客户端应用程序。 但问题是当应用程序打开时，数据出现时通知不会触发（我的意思是我登录了它）这不是问题。但是，当应用程序关闭时，会收到通知，而我单击通知时，活动已打开，而我无法查看日志数据。我需要将数据更新到一个TextView ..

我MyFirebaseMessagingService：

public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO: Handle FCM messages here. 
     // If the application is in the foreground handle both data and notification messages here. 
     // Also if you intend on generating your own notifications as a result of a received FCM 
     // message, here is where that should be initiated. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
     Log.e("FROM", "From: " + remoteMessage.getFrom()); 
     String data = remoteMessage.getData().get("message"); 
     Log.e("KOIII", "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
     // showNotificationS(remoteMessage.getNotification().getBody(),2); 
     if(data.equals("true")){ 
      Log.e("DATA", "SUCCESS"); 
      // Fragment1.getInstace().updateTheTextView(data, data, data); 
     } 
    } 

我的清单：

<activity 
      android:name=".SplashScreen" 
      android:label="@string/app_name" 
      android:launchMode="singleInstance"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <activity 
      android:name=".myHome" 
      android:label="@string/app_name"> 
     </activity> 
<service android:name=".MyFirebaseMessagingService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.MESSAGING_EVENT"/> 
      </intent-filter> 
     </service> 
     <service android:name=".FirebaseIDService"> 
      <intent-filter> 
       <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> 
      </intent-filter> 
     </service>

FCM将不会显示通知，如果你的应用程序是在前台，所以你必须手动显示如下： -

@Override 
    public void onMessageReceived(RemoteMessage remoteMessage) { 
     // TODO(developer): Handle FCM messages here. 
     // If the application is in the foreground handle both data and notification messages here. 
     // 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. 
     Log.d(TAG, "From: " + remoteMessage.getFrom()); 
     Log.d(TAG, "From: " + remoteMessage.getData().get("message")); 
//  Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody()); 
     sendNotification(remoteMessage.getData().get("message")); 
    } 
    // [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, MarketActivity.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.ic_launcher) 
       .setContentTitle("Fred Notification") 
       .setContentText(messageBody) 
       .setAutoCancel(true) 
       .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)) 
       .setContentIntent(pendingIntent); 

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

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

当您发送带有da的通知消息有效载荷（通知和数据），并且应用程序在后台，您可以从用户点击通知后启动的意向附加项中检索数据。

从它启动时通报挖掘在MainActivity的FCM sample：

if (getIntent().getExtras() != null) { 
    for (String key : getIntent().getExtras().keySet()) { 
     String value = getIntent().getExtras().getString(key); 
     Log.d(TAG, "Key: " + key + " Value: " + value); 
    } 
}
