Kotlin
Hold
What
Kotlin is a statically-typed JVM language and the standard for native Android development. At Doccla it's used only in legacy OTH wrappers in the Android mobile client.
Why this ring
Our mobile work targets React Native, not native Android. Kotlin survives only in legacy wrappers and isn't where we're putting new effort.
What does this mean
Not the target for new mobile work. The existing wrappers are maintained; new mobile work should be built in React Native.
