When I copy-pasted your code into my empty activity I got several errors(it seems your code is incomplete). I added these lines to make it work:
int notificationId = 1;
Intent intent = new Intent(this, MyActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
//Here goes your code.
I just tested your code on a 3.2 emulator and this is what the notification looks like:
Which, I believe, is what it should look like.
Coult you test with my code and let me know if it works?
