Read Content From Notification Parcelable Objects For Consequent Notification

I am trying to build Whatsapp Notification filtering app, where I monitor all notification from Whatsapp and remove messages as per filtering policy. I can fetch message content us

Solution 1:

Yes, finally after few hours of googling I design a code which does work for me.

Bundle extras = sbn.getNotification().extras;
    CharSequence[] lines = extras.getCharSequenceArray(Notification.EXTRA_TEXT_LINES);
    JSONArray s = newJSONArray();
    for (CharSequence msg : lines) {
                    msg = removeSpaces(msg);
                    if (!TextUtils.isEmpty(msg)) {
                        s.put(msg.toString());
                    }
                }
    privatestaticStringremoveSpaces(@Nullable CharSequence cs) {
            if (cs == null)
                returnnull;
            Stringstring = cs instanceofString ? (String) cs : cs.toString();
            returnstring.replaceAll("(\\s+$|^\\s+)", "").replaceAll("\n+", "\n");
        }

here JSONArray s contains all messages that I want
