How to call onCreateOptionsMenu from code

Question

I want to call onCreateOptionsMenu from the code because if i use:

menu.setGroupEnabled(0, false);

With:

public Menu menu;

public boolean onCreateOptionsMenu(Menu menu) {
    this.menu = menu;
    menu.add(0,0,0,"Option");
    return true;
}

It doesn't work if the user never pressed menu button. How can I do that?

Thanks

PS: If this is a bad practice let me know

I believe you want invalidateOptionsMenu()
