Solution
In Tablets running Android 4+, it is not possible to hide the System / Navigation Bar.
From documentation (Controls for system UI visibility section) :
The `SYSTEM_UI_FLAG_HIDE_NAVIGATION` is a new flag that requests the navigation bar hide completely. Be aware that this works only for the navigation bar used by some handsets (it does not hide the system bar on tablets).
However, you could try to dim the system bar as done sometimes during gaming and video playback.
The `SYSTEM_UI_FLAG_LOW_PROFILE` flag replaces the STATUS_BAR_HIDDEN flag. When set, this flag enables “low profile" mode for the system bar or navigation bar. Navigation buttons dim and other elements in the system bar also hide. Enabling this is useful for creating more immersive games without distraction for the system navigation buttons.
Problem
At my Tablet, it has following bar to control back, home etc. (I don't know the correct name, status bar? control bar? Action bar? or other) In program, it use following method to have a full screen. ``` requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); requestWindowFeature(Window.PROGRESS_INDETERMINATE_OFF); ``` But I don't know why the bar still in here. Because of it, I can't have the correct screen size. Who can tell me how to remove it?
