You can't handle Home button click, because of Android policy (Home button click event handling android). Of course, you can use onPause()/onStop() method of your current Activity, but your application will be moved to background too quick and user will not see your dialog, I think.

Also, note that Home not closes the app - just moves to background. User usually close app by pressing Back on main activity, try to handle it:

@Override
public void onBackPressed() {
    // your dialog here
}

Is is not possible for Android apps to override the functionality of the home button. The best you can do is show the dialog when the user presses back in your topmost Activity.
