To use an API, your device must support the SDK version in which the API was implemented or higher.

To check the Knox SDK version that is supported on your device, you can use this API method.

You can find the SDK version from which the API is supported in Javadoc.

If the value returned on your device is 5.0 or higher, you can successfully use the allowDeveloperMode() API method.

hideStatusBar() will hide/show (true to hide and false to show) the status bar that runs along the top of the screen.

hideSystemBar() is meant for tablets that have a soft navigation bar along the bottom of the screen.

It is recommended not to use hideSystemBar() on the devices that do not have a system bar. This is because, using hideSystemBar(false) on devices that do not have a system bar can interfere with the setting of hideStatusBar().

You cannot block multi-window mode through blacklisting. The reason being it is an application that is already preinstalled on the device firmware, and the blacklisting APIs have no effect on application packages that are already installed.

You must use the API method allowMultiWindowMode(false) to disable multi-window mode.
