I'm currently writing a book about Kotlin for Android Developers:https://leanpub.com/kotlin-for-android-developers https://leanpub.com/kotlin-for-android-developers Overall I think it is a really interesting language for Android (and I guess Java) developers. It's much cleaner and safer. I recommend at least taking some time to play with it and see how it looks. I also have some simple articles at my blog, antonioleiva.com, very basic and perfect to start with it.
