Your example run on both real device and emulator.
So I think that you could have some problems with B4A installation.
I would suggest to reinstall everything from zero like a first install redownloading all the needed components, from here:
https://www.b4x.com/b4a.html
Otherwise explain better if you get the error on startup or doing some actions.
