Starting with API level 5, you can override onBackPressed().
For previous API levels, use something like:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
// your code here
return true;
}
return super.onKeyDown(keyCode, event);
}
Whether this is a good idea is another question.
Also note that the user can still use the Home key to leave the activty,
and you can't override that.
