Who knows how to run kotlin and Java together on a Java android project

Question

Java android and kotlin

Answer 1

You cannot mix Java and Kotlin codes together in the same source file, but your project can contain both Java and Kotlin source files. The files can interface with each other: Calling Kotlin code in Java is done the same way as you would call a Java class in another Java class. Have you tried anything specific? Did any of your attempts fail?
