Hide navigation bar for kindle fire 3 and kindle fire HDX

Question

My code :

 s_activity.runOnUiThread(new Runnable()
            {
                @Override
                public void run()
                {   
                        //hide nub
                        View view = s_activity.getWindow().getDecorView().findViewById(android.R.id.content).getRootView();
                        view.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE | View.SYSTEM_UI_FLAG_FULLSCREEN | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
                }
            });

I use this code to hide the nub bar while playing the game. But it only works with devices: KF 1, 2. As for KF 3, the nub bar is not really hidden. It's just hidden in 1 second. Then nub bar will show if there is no interaction with the screen. So how to nub bar does not show while my application is running??

There seems to have been a bug with Fire OS 3.0 and 3.1 and the SYSTEM_UI_FLAG_FULLSCREEN. They claim it was fixed in Fire OS 3.2.1. Link: https://forums.developer.amazon.com/forums/thread.jspa?messageID=6004&#6004

If you upgrade to latest perhaps the SYSTEM_UI_FLAG_FULLSCREEN flag will work. I am using SYSTEM_UI_FLAG_LOW_PROFILE which still doesn't work on 3rd generation Kindle, which I reported here: https://forums.developer.amazon.com/forums/thread.jspa?threadID=3514
