Android SDK has extensive support for menus. It supports regular menus, submenus, context menus, icon menus, secondary menus, and alternative menus. Android 3.0, in addition, introduced the action bar, which integrates well with menu items. The action bar and menu interaction are covered in Chapter 10. Now Android 4.0 has introduced pop-up menus: menus that can be invoked at any time based on a button click or any other UI event.
