Hi. I have 2 questions:
1) In Code Editor(1.0) in options there is a section of the Android Certificate. For what need a certificate? How to properly set it up?
2) When I purchased the engine(1.0), I got a license key. What should I do with it?

thanks in advance

1, google Android Certificate
2. don't know, i use v2

1) it's required when publishing apps on Google Play
2) currently v1 license key is not used for anything other than proof of purchase

Thanks ))
