My personal recommendation is (for now) to use the android api to build a native app. Scala can help to build this native apps with cleaner code but it adds to many methods (Multidex required). Kotlin is a modern language with 100% interoperatibility with java projects without multidex. But there are also use cases where alternatives like cross-platform development can be useful.
