        if (DEBUG) Log.v(TAG, "setSystemBarVisibility: " + visibility);

        if (visibility == View.GONE && mNavigationBarView != null) {

            try {

                mWindowManager.removeViewImmediate(mNavigationBarView);

                Settings.System.putInt(mContext.getContentResolver(), Settings.System.SYSTEM_BAR_DISPLAY , 0);

Log.d("daibin","statusbar setSystemBarVisibility gone"); 

            } catch (IllegalArgumentException e) {

                Log.w(TAG, "IllegalArgumentException: " + e);

            }

            mNavigationBarView = null;
