2Android ActionBarCompat-Basic Sample
3===================================
4
5This sample shows you how to use ActionBarCompat to create a basic Activity
6which displays action items. It covers inflating items from a menu resource,
7as well as adding an item in code.

9Introduction
10------------
11
12Android 3.0 introduced the “action bar” control, a toolbar that is expected
13to be present in most types of applications. This control identifies the user
14location, and provides user actions and navigation modes.
15Using the action bar offers your users a familiar interface across applications
16that the system gracefully adapts for different screen configurations.
17
18Instantiating an action bar can be done by using the [ActionBar][1] API provided
19in API 11 or above. Support for older devices is provided by the
20[support library’s ActionBar][2] implementation, compatible back to API 7.
21This sample demonstrates using the support library APIs.
22
23Using an ActionBar with the support library requires the following steps:
24
251. Create your activity by extending AppCompatActivity.
262. Use (or extend) one of the Theme.AppCompat themes for your activity.
27
28Once this is done, action items will be created for any options menu items that
29would otherwise be created during when `[onCreateOptionsMenu()][3]` is called.
