沒有從Facebook SDK獲取所有通知，Graph-API

Question

我在製作應用程序，我需要從Facebook獲取所有新通知。我成功登錄並獲得manage_notifications權限給我的應用程序。這段代碼成功地從Facebook加載JSON字符串。

Session session = Session.openActiveSessionFromCache(ctx); 
    if (session != null && session.isOpened()) { 
     Request notificationsRequest = Request.newGraphPathRequest(
       session, "/me/notifications", 
       new Request.Callback() { 

        @Override 
        public void onCompleted(Response response) { 
         GraphObject object = response 
           .getGraphObject(); 
         if (object != null) { 
          notificationsNewString = object 
            .getInnerJSONObject() 
            .toString(); 

          try { 
           notificationsOldString = saver.getJsonFromInternalCache(); 
          } catch (IOException e) { 
           notificationsOldString = null; 
          } 
          try { 
           compareOldAndNewData(); 
          } catch (ParseException e) { 
           e.printStackTrace(); 
          } 

          createNotif(); 

         } else { 
          notificationsNewString = "Notifications returns null"; 
         } 

        } 
       }); 
     Request.executeBatchAndWait(notificationsRequest); 
    } else { 
     Log.i("TAGTAG", "Session not open!"); 
    } 

但是有些人對應用程序有困難，因爲Facebook不會發送json所有新通知。特別是在有人評論他們評論的狀態時發出通知。 （在Facebook上它被標記爲一個新的通知，但json是空的）。

它關於一些權限或它是錯誤？

謝謝。

我找到了另一種方法。萬一有人發現，我將它張貼它的幫助

private void onSessionStateChange(Session session, SessionState state, Exception exception) { 
if (state.isOpened()) { 
    InboxMessage.setVisibility(View.VISIBLE); 

    new Request(session,"/me/notifications", null,HttpMethod.GET,new Request.Callback() { 

       public void onCompleted(Response response) { 
        GraphObject object = response.getGraphObject(); 
         if (object != null) { 
          InboxMessage.setText(object.getProperty("data").toString()); 
         } else { 
          InboxMessage.setText("Notifications returns null"); 
         } 
       } 
      } 
     ).executeAsync(); 
} else { 
    InboxMessage.setVisibility(View.INVISIBLE); 
    Log.i(TAG, "Logged out..."); 
} 
}
