Block/Disable Statusbar in android Tablet/Mobile

Question

I have seen Kioware and SureLock applications. They simply block every control in tablet. I'm aware about overriding back button and handling the home and recent task options as well. But I'm not sure how they managed to control the setting option on system bar. Settings appear for a fraction of seconds and then disappear. In the same way Statusbar of mobile which appear on swipe down need to be block.

If anyone have idea about it please share it. Any guidance/help is appreciated.

You can try to add a transparent View at desidered position using the WindowManager (follow this example). In this way, you will intercept any tap events from the user.

Be sure to set the proper flags/type, because you need to overlay the system bars:

    WindowManager.LayoutParams dismissParams = new WindowManager.LayoutParams(
                        viewWidth,
                        viewHeight,
                        WindowManager.LayoutParams.TYPE_SYSTEM_ALERT, //you can also try with TYPE_SYSTEM_OVERLAY, TYPE_SYSTEM_ERROR
                        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
                        PixelFormat.TRANSPARENT);
