1Android AdvancedImmersiveMode Sample
2===================================
3
4Immersive Mode, added in Android 4.4, improves the "hide full screen" and
5"hide nav bar" modes by letting users swipe the bars in and out. This sample
6lets the user experiment with immersive mode by seeing how it interacts
7with some of the other UI flags related to full-screen apps.

9Introduction
10------------
11
12Android 4.4 (API Level 19) introduces a new `SYSTEM_UI_FLAG_IMMERSIVE`
13flag for [setSystemUiVisibility()][1] that lets your app go truly "full
14screen." This flag, when combined with the `SYSTEM_UI_FLAG_HIDE_NAVIGATION` and
15`SYSTEM_UI_FLAG_FULLSCREEN` flags, hides the navigation and status bars
16and lets your app capture all touch events on the screen.
17
18When immersive full-screen mode is enabled, your activity continues
19to receive all touch events. The user can reveal the system bars with
20an inward swipe along the region where the system bars normally
21appear.
