Firstly, go to settings, and then navigate to plugins. Find the kotlin plugin and update it.

Next, In gradle files, go to build.gradle (Project: YourApp). Then, change the following code (in buildscript) from:

ext.kotlin_version = '1.3.50'

to the latest version, such as:

ext.kotlin_version = '1.4.32'

To know the latest version, go to settings and the plugins, find kotlin plugin, and make sure it is updated. The latest version is under Jetbrains.

After following the instructions, your error will be resolved.

Another solution is to downgrade androidx.core:core-ktx library to any compatible version, this one worked for kotlin_version = '1.3.31':

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'androidx.appcompat:appcompat:1.3.1'  // The only working for this version (sdk/gradle)
    implementation 'androidx.core:core-ktx:1.0.2' // The only working for this version (sdk/gradle)
    implementation 'androidx.constraintlayout:constraintlayout:1.1.2' // higher versions require min-sdk >= 26
    ...
}

Android SDK: compileSdkVersion 30 and minSdkVersion 19.

Gradle build Tool: com.android.tools.build:gradle:3.3.1.

While I don't know how to specifically help with the build issues (though check the answer links I shared in comments above), for the name & email collection you would need to build UI for this.

You can add these billing_details (API) in the payment method create parameters (source) as seen in this Card element example, extended with optional values for name and email similar to this test.

what solved my problem is changing this at build.gradle

from

ext.kotlin_version = '1.3.50'

to

ext.kotlin_version = '1.6.0'

or what ever the latest version of Kotlin available and make sure to update Kotlin version on Android Studio as well

Make sure that the Kotlin version of your IDE is the same as the version declared in your gradle.build file.

Question: What you need to do to solve this?

Answer: I was facing this issue since last night. Just navigate through some webpages couldn't get to the exact solution finally solved it by these steps, Replace ext.kotlin_version = '1.3.50' to ext.kotlin_version = '1.4.32' in build.gradle file. Clean project -> Build the project with gradle files -> Run

✔️ Fixed by updating kotlin gradle plugin version.

In project level build.gradle file, update the following line.

ext.kotlin_version = '1.6.10'

You can find the latest kotlin gradle plugin version here https://kotlinlang.org/docs/gradle.html

I have face this error in Intellij Idea with Maven project. The solution is about to turn off Kotlin plugin in Intellij Idea if you are not using Kotlin in your project.

Go To:

File > Settings > Plugins

and turn off kotlin plugin by click on check box. See here

Most of the answers here seem to revolve around projects that use Gradle.

I randomly encountered this problem in IntelliJ that that was compiling and running a Maven project just fine 5 minutes before - no config changes. Introduced a new exception class and this problem popped up.

I tried invalidating caches and restarting, which didn't resolve the issue - however, disabling and re-enabling the Kotlin plugin resolved the issue.

Hopefully this can help someone who encounters this issue using Maven.

If you are facing this Error in Flutter build for Android the try to change the Kotlin version to

ext.kotlin_version = '1.4.32'

Using Flutter, Fixed by:

• Updating Android Studio packages, specially Kotlin plugin.

• Get the last Kotlin plugin version Nbr from Gradle - Plugin and versions, for now it's 1.6.10.

• Update <Your_project_name_folder>\android\build.gradle file by replacing the old kotlin version by the new one you got from the web site above.

  ext.kotlin_version = '<The_new_version_Nbr>' in my case ext.kotlin_version = '1.6.10'

• Restart VS Code.

You're Done.

Had this problem in Flutter project

in my case line for kotlin-gradle-plugin was missing in adnroid build.gradle, so adding ext.kotlin_version = '1.6.10' didnt not fix it.

After adding

classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

error was gone.

Full code section:

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}
