What's new in Kotlin on Android, 2 years in
summary
Google announces Kotlin-first for Android and cites adoption metrics: about 16% active apps and 44% of top‑1000 apps use Kotlin. Work targets tooling, runtime and language: Android Studio bundles the Kotlin plugin, Lint uses UAST, R8 adds Kotlin shrinker optimizations, and coroutines land in many Jetpack libraries. Language advances include experimental annotations, contracts, a multiplatform expect/actual model, a reflection‑free serialization library, and ongoing compiler/build speed improvements plus Kotlin Everywhere trainings.
