How to read notifications correctly on Android

Question

I am developing an App for read notifications all my code work great, but have two problems. I use this code for read notifications:

   String pack = sbn.getPackageName();
        String ticker ="";
        if(sbn.getNotification().tickerText !=null) {
            ticker = sbn.getNotification().tickerText.toString();
        }
        Bundle extras = sbn.getNotification().extras;
        String title = extras.getString("android.title");


        //String text = extras.getCharSequence("android.text").toString();
         String text = null;
        if (extras.getCharSequence("android.text") != null) {
            text =(String) extras.getCharSequence("android.text");
        }
        if (text == null) {
// for whatsapp on kitkat second whats app text
// will be null
            if (extras.get("android.textLines") != null) {
                CharSequence[] charText = (CharSequence[]) extras
                        .get("android.textLines");
                if (charText.length > 0) {
                    text = charText[charText.length - 1].toString();
                }
            }
        }

The code works, but the problem is with WhatsApp, when I receive more than one message I get the following structure.

Title: NameUser
Text: Hi, how are you?  <---- This is ok!

but the second message I get

Title: NameUser
Text : Hi again! <--- This is ok;

Title: NameUser
Text: 2 New messages <---- Agggr that is wrong!!!!!

How can avoid the "2 New messages"??

And the second question is Can I get images send via whatsapp? For the moment I only get the following structure.

Title: NameUser
Text: Image 

Thanks in advance

There is no way you can influence (from your app) what notifications are sent by some other app's server to your phone.
