Answer 3

Why enter developer mode? An application is written that shows ads and keeps the screen on, no developer mode is needed for this. 10-20 man hours of work edge.

Answer 4

I have an application for android, for children, I bought it for my son. It prevents screen blanking by default. If the son played and threw the phone somewhere, then it will shine for hours and show cars)
So smoke the Android SDK, there is probably such a feature.
