The latest Android Studio 3.0 features full out-of-the-box Kotlin support, newest Android Gradle plugin with Java 8 libraries, performance enhancements, smoother build process and easier performance debugging. Additionally, developers will now be able to create Instant Apps, and all of this with almost the same system requirements (with only a little bumped up disk space demands).

Why Kotlin?

Kotlin is a modern Java alternative developed by JetBrains (yep, same guys) that is quickly rising on the scene. It’s cleaner, safer, open source, and 100% interoperable with the existing Android languages. It offers significant advantages for JVM and Android development and works well with Java in the same projects.

Google first announced Kotlin compatibility back in May at the I/O conference. And now Android Studio fully support hustle-free automatic conversion of any Java code into Kotlin on-the-go.
