How to show a top bar message in Android

Question

I want to show this kind of message in Android top after finishing some background work. How do I show this kind of notification ? Thanks..

Answer 1

That looks like the ticker text of a Notification, assuming that this screenshot is of the top of the screen. You can add that to the Notification via setTicker() on your NotificationCompat.Builder. Note, though, that ticker text is no longer displayed as of API Level 21 (Android 5.0). Also note that ticker text automatically disappears after a couple of seconds.
