Its a security issue  https   stackoverflow com a 12605313 1303691  therefore its not possible to hide the Navigation on a tablet permanently with one single call at the beginning of the view creation  It will be hidden  but it will pop up when touching the Screen  So just the second touch to your screen can cause a onClickEvent on your layout  Therefore you need to intercept this call  but i haven t managed it yet  i will update my answer when i found it out  Or do you now the answer already

Do this   public void FullScreencall         if Build VERSION SDK INT  gt  11  amp  amp  Build VERSION SDK INT  lt  19       lower api         View v   this getWindow   getDecorView            v setSystemUiVisibility View GONE         else if Build VERSION SDK INT  gt   19              for new api versions          View decorView   getWindow   getDecorView            int uiOptions   View SYSTEM UI FLAG HIDE NAVIGATION   View SYSTEM UI FLAG IMMERSIVE STICKY          decorView setSystemUiVisibility uiOptions             This works 100  and you can do same for lower API versions  even if it s a late answer I hope it will helps someone else   If you want this to be permanent  just call FullscreenCall   inside your onResume   method

Use -  view setSystemUiVisibility View SYSTEM UI FLAG HIDE NAVIGATION     In Tablets running Android 4   it is not possible to hide the System   Navigation Bar   From documentation         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

For people looking at a simpler solution  I think you can just have this one line of code in  onStart      getWindow   getDecorView   setSystemUiVisibility              View SYSTEM UI FLAG HIDE NAVIGATION              View SYSTEM UI FLAG IMMERSIVE STICKY     It s called Immersive mode  You may look at the official documentation for other possibilities

It s my solution   First  define boolean that indicate if navigation bar is visible or not   boolean navigationBarVisibility   true   because it s visible when activity is created   Second create method that hide navigation bar   private void setNavigationBarVisibility boolean visibility       if visibility           View decorView   getWindow   getDecorView            int uiOptions   View SYSTEM UI FLAG HIDE NAVIGATION                   View SYSTEM UI FLAG FULLSCREEN          decorView setSystemUiVisibility uiOptions           navigationBarVisibility   false             else         navigationBarVisibility   true      By default  if you click to activity after hide navigation bar  navigation bar will be visible  So we got it s state if it visible we will hide it   Now set OnClickListener to your view  I use a surfaceview so for me       playerSurface setOnClickListener new View OnClickListener              Override         public void onClick View v                setNavigationBarVisibility navigationBarVisibility                       Also  we must call this method when activity is launched  Because we want hide it at the beginning           setNavigationBarVisibility navigationBarVisibility

According to Android Developer site  I think you cant as far as i know  hide navigation bar permanently    However you can do one trick  Its a trick mind you   Just when the navigation bar shows up when user touches the screen  Immediately hide it again  Its fun   Check this   void setNavVisibility boolean visible    int newVis   SYSTEM UI FLAG LAYOUT FULLSCREEN           SYSTEM UI FLAG LAYOUT HIDE NAVIGATION           SYSTEM UI FLAG LAYOUT STABLE  if   visible        newVis    SYSTEM UI FLAG LOW PROFILE   SYSTEM UI FLAG FULLSCREEN               SYSTEM UI FLAG HIDE NAVIGATION        If we are now visible  schedule a timer for us to go invisible  if  visible        Handler h   getHandler        if  h    null            h removeCallbacks mNavHider           if   mMenusOpen  amp  amp   mPaused                   If the menus are open or play is paused  we will not auto-hide              h postDelayed mNavHider  1500                         Set the new desired visibility  setSystemUiVisibility newVis   mTitleView setVisibility visible   VISIBLE   INVISIBLE   mPlayButton setVisibility visible   VISIBLE   INVISIBLE   mSeekView setVisibility visible   VISIBLE   INVISIBLE       See this for more information on this     Hide System Bar in Tablets
