Hi, I am working on android studio project and this error keeps showing. I have synced project with gradle file but doesn’t work.

The build scan is not too useful as it is not if the failing build.
But anyway this is not really a Gradle topic. You try to use a Kotlin 1.9 compiled library while compiling with Kotlin 1.7, this does not work.

Hi, I know it’s not a gradle topic but do you know how to solve the error? I have changed the Kotlin compiler version but still doesn’t work.

I can only guess that you did not do it correctly.
You either cannot use what was compiled with Kotlin 1.9 when compiling with 1.7, or need to compile with newer than 1.7.

Hi- i’m also experiencing this error: Class 'kotlin.collections.ArraysKt___ArraysKt' was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.8.0, expected version is 1.6.0.

Among a mass of similar errors regarding Kotlin versions.

This happened after coming back to a project to make a small tweak, and found myself needing to upgrade Gradle for Play Store compliance. I don’t use Kotlin in my project, as it’s a React Native app. Anyone have some suggestions? I’ve tried setting the kotlinVersion = “1.6.0” in the android/app/build.gradle with no luck

The error says you are using Kotlin 1.6.x but try to use a library that was compiled with Kotlin 1.8.x and thus is not compatible as Kotlin 1.6.x can read at most libraries compiled with Kotlin 1.7.x.

7

Do you have any suggestions that would help determine what library or libraries may be incompatible? Assuming it’s whatever React Native is trying to use, but not what i’ve personally added.

In my android/build.gradle:

dependencies {
        classpath("com.android.tools.build:gradle:8.5.0")
        classpath("com.facebook.react:react-native-gradle-plugin")
    }

and in my android/app/build.gradle:

dependencies {
    // The version of react-native is set by the React Native Gradle Plugin
    implementation("com.facebook.react:react-android")

    implementation("androidx.swiperefreshlayout:swiperefreshlayout:1.0.0")

    debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}")
    debugImplementation("com.facebook.flipper:flipper-network-plugin:${FLIPPER_VERSION}") {
        exclude group:'com.squareup.okhttp3', module:'okhttp'
    }

    debugImplementation("com.facebook.flipper:flipper-fresco-plugin:${FLIPPER_VERSION}")
    if (hermesEnabled.toBoolean()) {
        implementation("com.facebook.react:hermes-android")
    } else {
        implementation jscFlavor
    }
}

Do you have any suggestions that would help determine what library or libraries may be incompatible?

Actually the error says the problematic class is kotlin.collections.ArraysKt___ArraysKt, so it is kotlin-stdlib library.
Check in a build --scan or with dependencies or dependencyInsight tasks which version you’ve got and where it comes from.

I just run with scan

You may have run with --scan, but you did not provide the build scan URL

Sorry, here`s the link Build Scan® | Develocity

I assume the react native Version you use is not compatible with the Gradle version you use. Make sure your use a compatible setup.

tks bro!
This solved for me here!
Savede my day!!
