[Feature Request][Android] Kotlin native extensions support #2046

Open itlancer opened 2 years ago

itlancer commented 2 years ago

Feature Description

AIR should support native extensions developed using Kotlin for Android platform. Nowadays many Android third-party libraries supports only Kotlin, not Java. Moreover it has more performance and recommended by Google for Android. Even some new Android libraries support only Kotlin: https://developer.android.com/guide/topics/renderscript/migrate#intrinsics

Known Workarounds

It's not that hard to keep the main freextension, frecontext and frefunctions as java and use kotlin for everything else in your extension. Kotlin is designed with java interoperability in mind so they work well together. We actually do this in several of our extensions already.

tuarua isn't really a workaround but just a demonstration on how you can use kotlin in an ANE. He does take it to the next level and create utilities for returning / converting freobjects but this is really implementation side of an ANE.
