Easy way to hide system bar on Android ICS

Question

I will give my ICS tablets for users to complete a survey so I would like the user to work with my app only. They should not be able to switch to the home screen, press back

Answer 1

Google intends Android to be used for consumers only. They integrated the System UI bar more tightly into Android ICS (4.0) to prevent people from rooting the device and killing the bar that way. Attempting to delete the system bar process will prevent the OS from booting fully.

If you want to restrict users from accessing the home screen, then you are out of luck with Android ICS. I would suggest finding a tablet manufacture who will preload the device with Android 2.3. Either that, or use a rooted Android 3.x device.

If you intend to use Android for kiosk or locked down devices, then you would be better off targeting an OS that is a bit more open.
