How do I implement an option menu in my android application? I tried code from Android Developer but I get errors. Such as these: Element menu must be declared.

You should use onCreateOptionsMenu (Menu menu)

Initialize the contents of the Activity's standard options menu. You should place your menu items in to menu.

This is only called once, the first time the options menu is displayed. To update the menu every time it is displayed, see onPrepareOptionsMenu(Menu).

onCreateOptionsMenu(Menu menu) method which needs to override in Activity class. This creates menu and returns Boolean value. inflate inflates a menu hierarchy from XML resource.

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.option_menu, menu); // set your file name
        return super.onCreateOptionsMenu(menu);
    }

Your option_menu.xml
