Conclusion. In general, because of the May 2019 announcement from Google I would recommend beginners at Android app development start with Kotlin however there are some exceptions where I think Java may be better . There are two scenarios I would recommend learning Java first for Android app development as a beginner.

Yes, the JDK is required for Kotlin development on the JVM . Kotlin works with JDK 1.6+.
