To put it into more perspective, I live in Orlando and Kotlin has been the new growing language for Android since before the announcement. Developers wind up trying Kotlin for themselves and enjoying it for themselves, the rising numbers and the fact Google realized it's popularity and adjusted their support for it shows that Kotlin is a reasonable solution for Android development. It also doesn't help the fact that Java is hostile against Android, and that Kotlin is working on native compilation, which could make it one day one of the most powerful assets of Android if they go full on for native compilation for Android, a benefit that afaik Java doesn't have.
