* over how the Action Bar is displayed, such as letting application content scroll beneath
* an Action Bar with a transparent background or otherwise displaying a transparent/translucent
* Action Bar over application content.
*
* This mode is especially useful with {@link View#SYSTEM_UI_FLAG_FULLSCREEN
* View.SYSTEM_UI_FLAG_FULLSCREEN}, which allows you to seamlessly hide the
* action bar in conjunction with other screen decorations.

As of {@link android.os.Build.VERSION_CODES#JELLY_BEAN}, when an

* {@link View#fitSystemWindows(android.graphics.Rect) View.fitSystemWindows(Rect)}
