I need perform some action on press of home 开发者_Go百科key like starting activity when some one presses the home key...how to do it?

If what you really want is to perform some actions when your activity leaves the foreground, see the activity lifecycle. Your activity will have its onPause method called when it is no longer in the foreground, and onStop called when it is no longer visible.
