I have a phone running Android 4.0 and I wish to know if it is possible to turn this phone into a dedicated calculator? When I say dedicated I mean - once the phone is turned on, it boots directly to a calculator GUI? Whereby the user can immediately starting using the calculator, just like any stock standard Android calculator app would look like.
I do not wish it to boot to a home screen in between, but directly to the calculator itself. I am using a very simple example here, in anycase, would this be possible?
