無法從onMessageReceived方法中使用fcm通知中獲取數據

當應用處於前臺時，無法接收推送通知。在後臺收到推送通知，但收到推送時無法獲取數據。它是由FCM無法從onMessageReceived方法中使用fcm通知中獲取數據

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.e("inside","inside"); 

     Log.d(TAG, "From: " + remoteMessage.getFrom()); 

     // Check if message contains a data payload. 
     JSONObject object=new JSONObject(remoteMessage.getData()); 
     Log.e("jsonobject",object.toString()); 
     if (remoteMessage.getData().size() > 0) { 
      Log.d(TAG, "Message data payload: " + remoteMessage.getData()); 
      sendNotification(remoteMessage.getData().toString()); 

//   if (/* Check if data needs to be processed by long running job */ true) { 
//    // For long-running tasks (10 seconds or more) use Firebase Job Dispatcher. 
//    scheduleJob(); 
//   } else { 
//    // Handle message within 10 seconds 
//    handleNow(); 
// 
//   } 

     } 

     // 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] 

    /** 
    * Schedule a job using FirebaseJobDispatcher. 
    */ 
    private void scheduleJob() { 
     // [START dispatch_job] 
     FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this)); 
     Job myJob = dispatcher.newJobBuilder() 
       .setService(MyJobService.class) 
       .setTag("my-job-tag") 
       .build(); 
     dispatcher.schedule(myJob); 
     // [END dispatch_job] 
    } 

    /** 
    * Handle time allotted to BroadcastReceivers. 
    */ 
    private void handleNow() { 
     Log.d(TAG, "Short lived task is done."); 
    } 

    /** 
    * 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.mipmap.ic_launcher) 
       .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()); 
    } 
}

自動生成的，我也得到這個

這是什麼'Log.e（「的JSONObject」，object.toString（））;'...顯示？ – rafsanahmad007

我正在嘗試打印從remoteMessage獲取的有效內容 –

請我如果您使用其他Google服務，則版本相同。看文件的build.gradle（模塊：APP）

compile 'com.google.android.gms:play-services-location:10.2.4' 
apply plugin: 'com.google.gms.google-services' 
compile 'com.google.firebase:firebase-messaging:10.2.4'

檢查清單文件是類似這樣的：

 ...<activity android:name=".actMyLastActivityFromManifest"></activity> 

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