The Action Bar
The action bar is a rectangular window area that contains the application icon, application name, menus and other navigation buttons. The action bar normally appears at the top of the window.
This chapter explains how to decorate the action bar on Android with API level 11 (Android 3.0) or higher.
The action bar is represented by the android.app.ActionBar class. It should look familiar to any Android user. Figure 29.1 shows the action bar of the Messaging application and Figure 29.2 shows that of Calendar.
