I can't imagine anyone who has used Scala for long would switch to Kotlin. Kotlin is 'Java++'. Scala is a fully featured functional language. Kotlin is missing all of the most powerful Scala features. No type classes, monadic comprehension, higher kinded types, adhoc polymoprhism. :(

Not everyone needs a functional language.

Well, it's kind of the point. Kotlin is supposed to be light weight and easy. Besides, using Scala for Android, while possible, is cumbersome. Kotlin wins this one hands down.

  Which issues did you experience?

  Scala for Android is fine. The only thing that makes it harder than Kotlin is JetBrains disingenuously shipping their Kotlin plugin but not their (more popular) Scala plugin by default, which they could fix tomorrow if they wanted to.

    Last I checked, Kotlin plugin isn't installed (in Android Studio) by default. Are you referring to IntelliJ Idea? I tried to use Scala for Android in the past and I gave up after attempting to set it up for a few hours. Admittedly it was a while back, perhaps things have improved. Your claim that Scala on Android works fine got me interested again, so I googled around, found that blog post from May this year (that's more recent than my own experiments), and apparently there are still hurdles: http://blog.scalac.io/2016/05/19/reflections-on-starting-android-project-with-scala.html http://blog.scalac.io/2016/05/19/reflections-on-starting-and... With this type of issues the thing that I'm wary about is not getting a "hello world" app to compile once, but that I can get a project up and running, then need to add something else to the equation (say, a DI, or some code processor), and things fall apart again in an X-Files fashion. I've heard that Scala has long build times, too, but maybe it's a thing of the past as well - no first-hand experience here as I never got to that stage.

      The article isn't very good, even the link to the 'official' page is outdated. Just use sbt-android and skip all the other nonsense. Compilation is impressively fast, as the plugin uses the information from incremental compilation to skip ProGuarding completely for things that haven't changed.
