I have developed an app for a job that will be used by their customers.
Each customer (Anonymous) enters there, uses app (tablet) and then leave.
The thing is that I want the users not to leave my app on tablet.
For this purpose I have blocked back button with a pass code but still the user can press home button, multi task button, or even swipe notification bar down and go to other locations.
Up to now I am thinking of a custom ROM that allows me block or remove all this possibilities. Although may be more simple ways than a custom ROM may be available that didn't reach to my mind.
Any suggestion is welcome.
Thanks in advance. TG.
