Kotlin cannot access kotlin.jvm.functions.Function1 when calling kotlin function with java lambda

My problem got fixed when I configured Kotlin compiler and runtime for my Java module with the latest stable version (currently 1.3.30)

Just go to Tools > Kotlin > Configure Kotlin in Project > Android with Gradle and choose your Java module with Single module radio button selected then select your version and OK.


Another Solution:

If you have several modules in your android project, please make sure you have added the below config to every module that uses the kotlin:

Step(1)- Project build.gradle:

// Project build.gradle file.
buildscript {
    ext.kotlin_version = '1.3.30'
    ...
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

Step(2)- Inside each module using kotlin:

apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-android'

...

dependencies {
   implementation "androidx.core:core-ktx:1.0.1"
   implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}
