Confusion over the various lua files

Getting Started Newbie Questions
#1

I have lost a few hours using the wrong json.lua file. I see there is a ui.lua and a coronaui.lua file.

Which is the correct one to use ?

I presume people enhance the files ?

Is there a list of the std lua files for use.
Cheers

Ha Ha… I found the coronaui.lua

I have just built the new coffee sample and installed on an Advent android 2.2 . When I run the app it doesn’t run at all
