This solution works from android 2.1,

Okay, this was supposed to be a hard question. But here is a way to crack it.

Override the below method in your Activity,

@Overridepublic void onAttachedToWindow() {    super.onAttachedToWindow();    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);           }

And now handle the key event like this,

@Overridepublic boolean onKeyDown(int keyCode, KeyEvent event) {   if(keyCode == KeyEvent.KEYCODE_HOME)    {     Log.i("Home Button","Clicked");    }   if(keyCode==KeyEvent.KEYCODE_BACK)   {        finish();   }return false;};
