Your Switch case must be like the following

Code borrowed from here

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
    case R.id.new_game:
        newGame();
        return true;
    case R.id.quit:
        quit();
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

Don’t use your own Constants, use the ones that are generated in R file.
