                    WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,

                   | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
           window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                   | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
