Generally, non-Kotlin questions, even if related to Android should go to StackOverflow or other Android communities like:

We do this to keep the non-Kotlin noise-ratio down...otherwise, people will just keep doing "I know this isn't Kotlin related, but I really need to find the best thingy that I can't figure out" and we'll have a lot of non-Kotlin noise here...
