On 7 May 2019, Google announced that the Kotlin programming language is now its preferred language for Android app developers. As a result many developers have switched to Kotlin Since the release of Android Studio 3.0 in October 2017, Kotlin has been included as an alternative to the standard Java compiler. The Android Kotlin compiler targets Java 6 by default, but lets the programmer choose to target Java 8 up to 13, for optimization or more features.
