问题
I have found non rooted apps which are capable of hide home button from bottom system bar of tabs (not all the devices but many of samsung tabs) & disabling (not hiding) right side wifi, settings entering panel in system bar (worked in all the testing devices). Good example is remote lock screen of Lookout premium app with BIND_DEVICE_ADMIN permission. This lock screen appears on top of the native android lock screen it has these features work in many devices.
Is there a way to create an activity with disabling System bar like that? Is it related to the flag that adding to the layout params of the activity? Otherwise how this is implemented?
Thanks.
