因为您在控制台中看到日志消息，所以您已经正确地处理了FCM部分，并且可能是您创建通知的问题。

如果你看在您的通知创建代码中，您缺少一些必需元素在Android上创建通知。从文档：

通知对象必须包含以下内容：

• 由setSmallIcon（）设置的小图标
  
• 由setContentTitle（）设置的标题


• 详细信息文本，由所以我想如果你添加这些项目到你的通知创建，你应该看到通知区域中的通知。
  

  I am having problem with FireBase push notifications. When my app is in the background, notifications are coming, but when my app is in the foreground i don't receive notifications, but in console that notification is displayed, that means that notification is here but it doesn't show in notification bar . Could you help me?

  @Override
  public void onMessageReceived(RemoteMessage remoteMessage) {
      Log.d("OnMessage", "Received");
      super.onMessageReceived(remoteMessage);
      Log.d(TAG, "From " + remoteMessage.getFrom());
      Log.d(TAG, "Body " + remoteMessage.getNotification().getBody());
      String aa=remoteMessage.toString();
      Intent intent=new Intent(MyFirebaseMessagingService.this, MainActivity.class);
      intent.putExtra("msg", aa);
      sendNotification(remoteMessage);
      NotificationCompat.Builder mBuilder =
          new NotificationCompat.Builder(this)
          .setContentText(remoteMessage.getNotification().getBody());
  
      // remoteMessage.getNotification().getBody();
  
  }
  
  
  private void sendNotification(RemoteMessage remoteMessage) {
  
      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)
          .setContentText(remoteMessage.getNotification().getBody())
          .setAutoCancel(true)
          .setSound(defaultSoundUri)
          .setContentIntent(pendingIntent);
  
      NotificationManager notificationManager =
          (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  
      notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
  }
  

  解决方案

  Like you said you are receiving the message since you are seeing the log messages in the console so you have handled the FCM part properly and the issue is likely with your creation of the notification.

  If you look at your notification creation code you are missing a couple of the required elements to create a notification on Android. From the docs:

  A Notification object must contain the following:

  • A small icon, set by setSmallIcon()
  • A title, set by setContentTitle()
  • Detail text, set by setContentText()

  So I think if you add those items to your notification creation you should see the notification in the notification area.
