3===================================
4
5Immersive Mode, added in Android 4.4, improves the "hide full screen" and
6"hide nav bar" modes by letting users swipe the bars in and out.  This sample
7lets the user experiment with immersive mode by seeing how it interacts
8with some of the other UI flags related to full-screen apps.

10Introduction
11------------
12
13Android 4.4 (API Level 19) introduces a new `SYSTEM_UI_FLAG_IMMERSIVE`
14flag for [setSystemUiVisibility()][1] that lets your app go truly "full
15screen." This flag, when combined with the `SYSTEM_UI_FLAG_HIDE_NAVIGATION` and
16`SYSTEM_UI_FLAG_FULLSCREEN` flags, hides the navigation and status bars
17and lets your app capture all touch events on the screen.
18
19When immersive full-screen mode is enabled, your activity continues
20to receive all touch events. The user can reveal the system bars with
21an inward swipe along the region where the system bars normally
22appear.
