Android show a notification not working

Question

Currently I have a service that plays music. I want to show a notification when the service start to play music. This is what I do:

public void setUpNotifica         


        

Answer 1

Per the notification guide list of required fields, you must set a small icon via the setSmallIcon() method. Generally, this icon looks like your application icon, although entirely as white over a transparent background per the anatomy of a notification.
