Is there any way to detect that user has pressed a home button ? is there exist an开发者_高级运维y unique method thatexecute as part of home button,am not meaning home button listener?

Android Activity lifecycle. OnCreate is called on the new activity, onPause on the old one.

You can't capture the home button press, or do anything with it, but onUserLeaveHint is called as an fyi.
