That's correct! I did not want to give up Clojure or Scala for Android however! I tried writing an app in both and it was miserable, so I went back to Java. And then I thought -- well, hang on, I'm definitely not going to write this in Java if there's a less-verbose alternative. So I forced myself to learn Kotlin and actually like it quite a bit. In a few ways, it reminds me of when I first worked with Groovy.
