Android Library Module developed in Kotlin referred in Java Application getting : Lkotlin/jvm/internal/Intrinsics exception

Question

Hi I am developing Android library using kotlin. And developing the Android application using Java. And I am referring the kotlin android library (aar) in the java application.

Everything works fine when I add the kotlin aar as module dependency in the java application. But when I refer the same kotlin aar using local maven repo getting the following error

              java.lang.NoClassDefFoundError: Failed resolution of: Lkotlin/jvm/internal/Intrinsics;

I found a post with similar issue but couldn't figure out the issue in my setup

Android Library Module developed in Kotlin exported to Java Application causing Failed resolution of: Lkotlin/jvm/internal/Intrinsics

Any help will be really useful.

Thank

Answer 1

Same problem on Xamarin.Android fixed by add reference NuGet Package: Xamarin.Kotlin.StdLib

Answer 2

Finally it worked for me after I added the kotlin configuration in Android java application

apply plugin: 'kotlin-android' and implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"

Answer 3

You have to use the standard library for the JVM:

implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
