Kotlin is now Google’s preferred language for Android app development | TechCrunch
"Google today announced that the Kotlin programming language is now its preferred language for Android app developers.
“Android development will become increasingly Kotlin-first,” Google writes in today’s announcement. “Many new Jetpack APIs and features will be offered first in Kotlin. If you’re starting a new project, you should write it in Kotlin; code written in Kotlin often mean much less code for you–less code to type, test, and maintain.”
