Didn't find class “androidx.core.app.CoreComponentFactory”

I don\'t know what to do about the following errors, I\'ve searched the web but not found anything:

java.lang.ClassNotFoundException: Didn\'t find class \"an         


        

Answer 1

Adding Java 1.8 compatibility to my build.gradle fixed this for me (non-release build with multidex enabled).

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
    jvmTarget = "1.8"
}

Unfortunately I'm not sure why :)
