I write Java for Android. But I'm more like jack of all trades, I'm not specializing on Android development. I know Kotlin, but it's too complex for my taste, so I'm avoiding it, Java works just fine. Actually the same for iOS and Objective C. I learned Objective C like 15 years ago and it didn't change much since then. I also learned Swift the day it was released and I know nothing about modern Swift, it changes so fast. I don't really care. Objective C works just fine for me too.
