Kotlin Static Analysis with Android Lint
summary
Android Lint supports Kotlin and already ships about 315 checks, runs ~75% of those on the fly in the editor, and now runs outside Android via a Gradle plugin for pure Kotlin projects. It exposes a detector API, uses UAST to analyze Java and Kotlin uniformly, loads custom lint checks from AARs, and packages quickfix descriptors plus a rich unit-test DSL. It enforces a ~40-check “target lint vital” on release builds, offers a baseline workflow to ignore existing warnings, and is adding an expensive but usable call-graph for interprocedural analysis.
