How to show a popup window on click of home key in android?

I have to show a popup window on click of home screen button. I have tried using the below code onkeydown(), but on click of home key button it's not coming into the loop.

if(keyCode == KeyEvent.KEYCODE_HOME)

{

  //do something

}

Also i tried using onUserLeaveHint(), but no use.

If any one knows about this kindly let me know.

It is not possible to override the home button, it is required by the system. See this answer by the Android Developer, Romain Guy https://stackoverflow.com/a/5039586/1578771.

Also, in future its better to use onKeyUp() as you'll be able to use other events like long presses etc.

You can't. The API doesn't let you capture the press of that key. It's a safety key. Refer to this question for more details.
