"Android Studio should currently not be used for development with sbt and Scala. Chances are, however, that it's a good fit for a Gradle + Scala setup."
Using InteliJ instead of Android Studio means not being able to use the latest tooling even from the stable version, as InteliJ is always some versions behind.
Using Gradle + Scala implies a few configuration steps that tend to break at each new Android Studio release, versus the out of the box experience from Kotlin.
