How to implement Android app using xojo?
You cannot build for Android at this time. It’s scheduled though 
@Albin Kiland Thank you for quick reply, Can you tell me when will it be available?
The expectation is for fourth quarter of 2017. I’d personally expect 2018 to be more realistic but happy to be proven wrong. Either way, it’s coming.
