If you have an overlay window attached in a WindowManager in your service, put your view the attribute setFocusableInTouchMode(true), and put a key listener. You'll receive key events, like in this example:

view.setFocusableInTouchMode(true);
view.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if(keyCode == KeyEvent.KEYCODE_BACK) {
            stopSelf();
            return true;
        }
        return false;
    }
});
