Thanks to above posts  here s the main lines - distilled from the longer code answers - that are necessary to connect a notification with click listener set to open some app Activity     private Notification getNotification String messageText         Notification Builder builder   new Notification Builder this       builder setContentText messageText                   Intent appActivityIntent   new Intent this  SomeAppActivity class        PendingIntent contentAppActivityIntent               PendingIntent getActivity                              this      calling from Activity                             0                              appActivityIntent                              PendingIntent FLAG UPDATE CURRENT        builder setContentIntent contentAppActivityIntent        return builder build
