Android studio - Reading whatsapp notifications problem

I'm developing an android app and part of it needs to read WhatsApp messages by the notifications and analyze them. I'm using a NotificationListenerService and it is working, however, I'm having a problem that notifications are being "analyzed" twice when I get the notification and then get a Message from other chat.

What I want is to analyze each message (Notification) once.

I already tried to save the notification sortKey or the StatusBarNotification key in a HashSet and then check, if it already contains the key every time, however that does not work.

Here is the code that in onNotificationPosted function - 

String pack = sbn.getPackageName();
       if (pack.equals("com.whatsapp")) {
            Bundle extras = sbn.getNotification().extras;

       if (extras.getCharSequence("android.text") != null && extras.getString("android.title") != null) {

       if (sbn.getNotification().getSortKey() != null) {
              String title = extras.getString("android.title");
              String text = extras.getCharSequence("android.text").toString();

            //Checking if it's from specic group and analyzing the message and 
            //doing what needs to be done, not related to the problem.                                      

            }
        }
    }

The result I want is that every notification will be analyzed once and not get posted again if some other messages arrive in other chats

Without knowing the inner workings of WhatsApp, it's hard to tell what you should exactly do, because it appears they reuse Actions/Extras for various things (which makes sense anyway).

In this case though, you could keep a list/map of the ones you've already "analyzed" and if you get it again, discard it.
