Recording brought to you by American Express https://americanexpress.io/kotlin-jobs Annotation processing is a powerful tool to extend your codebase at build time, and the advent of Kotlin in the android community introduces a dimension to this. Kapt works with existing Java processors, but it doesn’t come without its quirks at the interop layer. This talk will dive into how you can leverage Kotlin bytecode’s @Metadata annotations to better understand Kotlin code during annotation processing, covering anywhere from case studies in Dagger and Moshi to leveraging tools like KotlinPoet to even generate Kotlin code that seamlessly leverages language features.
