MenuItemCompat.setOnActionExpandListener is now deprecated

use

menu.findItem(R.id.action_search)setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
    @Override
    public boolean onMenuItemActionExpand(MenuItem menuItem) {
        return false;
    }

    @Override
    public boolean onMenuItemActionCollapse(MenuItem menuItem) {
        return false;
    }
});

instead
