I’m developing a managerial application for Android, using C# with Xamarin. There is some way to block the application (or lock all the buttons on the tablet) so that the user can not close it, unless with some password authorization. The user cannot use anything else from the tablet, only the application in question. Someone could assist me in how to proceed with this operation ?
You can not, the control of Android must be by the user and not by the application, but there are some "hacks gambiarras" as here: http://stackoverflow.com/questions/17549478/how-to-disable-home-and-other-system-buttons-in-android

It’s possible! It’s called Kiosk mode. I recommend this link: http://www.andreas-schrade.de/2015/02/16/android-tutorial-how-to-create-e-kiosk-mode-in-android/
