Action bar compatibility

Question

I notice that on the android developer web page, there is THIS document which is titled "Action bar compatibility" .

Does it show the action bar implementation with old android API less than v11 or does it show how to implement action bar with API v11 and greater? I get confused by this page.

Answer 1

This sample shows how to use the ActionBar design pattern on pre-API 11 devices and the built-in ActionBar on devices supporting API 11 or greater.

It shows 2 things:

1. How to use an action bar without the actual ActionBar object on pre-API 11 devices. A ActionBar is simulated.

2. How to use the ActionBar in Android 11+
