I basically want how to stop all other applicationa when my specific apllication is running. It's like in a BITSAT exam, when we log on for the quiz we cannot access internet and we can't access any drives of the computer. So I bascially want that interface to work on my Android, is there any way to do that?
This is called Kiosk Mode which is hot these days. Try SureLock Kiosk Lockdown app. You can try searching "Kiosk" in Play Store, too.
If you're on Lollipop, its easy to lock down the app. If you're on an earlier version of android, you need to:
- Set your app as a launcher
- Root your device
- Hide default soft buttons

Google recently released the Android Management API which allows to easily manage Android devices, lock them on a single application and set various other policies.
