Answer 1

I think it will close your activity and all Sub activity related to it.

public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();]
        if (id == R.id.Exit) {
            this.finishAffinity();
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
