Android Notification - ythy/blog GitHub Wiki
the constructor for Notification which is deprecated as of API 11. Meaning it isn't supported any longer and should not be used. use Notification.Builder instead
bad:
Notification notification = new Notification(icon, message, when);
right: build require API 16
Notification notification = new Notification.Builder(context)
.setContentText(message)
.setSmallIcon(icon)
.setWhen(when)
.build();
