Simply remove this button, as it is not necessary on Android. http://stackoverflow.com/questions/2033914/quitting-an-application-is-that-frowned-upon/2034238#2034238 — CommonsWare, Mar 08 '13 at 00:18

Don't break Android's paradigm. It's not up to you to decide when the close the application. Let the user and the OS take care of that.

If, for whatever reason, you really have to do this. You can just call finish(). This will shut down the current activity, leading to an eventual app closure if the activity is the only one on the history stack.
