- You want your action to happen only when you click on the home button, or any time your application should go to the background ?Dany Y– Dany Y2013-01-06 14:28:47 +00:00Commented Jan 6, 2013 at 14:28

Write your own home screen. When the user presses HOME, they will get a choice of running your app or the built-in home screen. They can elect to choose one just this one time, or set either app as being their default from now on. Many will wonder why on Earth you decided to decided to implement a home screen.
Most developers care about any case where their activity moves to the background, in which case you can either use a lifecycle method (e.g., onPause(), onStop()) or try onUserLeaveHint().

I do it this way:
/* Handles item selections */ @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: //You can do whatever you want here Intent homeInt = new Intent(this, SomeActivity.class); startActivity(homeInt); return true; } return false; }

Have you tried overriding onKeyDown()
@Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_HOME) { // ENTER CODE HERE return true; } return super.onKeyDown(keyCode, event); }
