2) https://github.com/vimeo/vimeo-networking-java/tree/develop/auth

3) https://github.com/acristescu/OnlineGo

4) https://github.com/codeka/wwmmo

5) https://github.com/gastsail/JetExample

6) https://github.com/SimpleMobileTools/Simple-Calculator

7) https://github.com/mipt-npm/kmath

Not sure about android apps

I don't think we should try with kmath :)

As for others, I think we should start with some projects with small code base and see if diktat can be integrated easily enough.

Not sure about Android either. Ktlint has some special rules, which I didn't dig into. Maybe we can try and see if there are any Android-specific problems.
