How to get text of Stacked Notifications in Android

Question

The question is how to get the TEXT (not title) field of all incoming notifications when they get stacked (like in Whatsapp).

Answer 1

If you're working with Android 7.0+, WhatsApp uses MessageStyle Expanded Notifications. Here - https://developer.android.com/training/notify-user/expanded.html#message-style

To retrieve all 5 messages from a notification like

MyFriend (5 messages)
testt

Do this:

Bundle extras = mysbn.getNotification().extras;
if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)){
        Parcelable b[] = (Parcelable[]) extras.get(Notification.EXTRA_MESSAGES);

        if(b != null){
            content = "";
            for (Parcelable tmp : b){

                Bundle msgBundle = (Bundle) tmp;
                content = content + msgBundle.getString("text") + "\n";

                /*Set io = msgBundle.keySet(); // To get the keys available for this bundle*/

            }
        }
    }

Same as my answer here.
