The binary version of its metadata is 1.5.1, expected version is 1.1.15&#8221; typically occurs when there is a version mismatch between the Kotlin compiler used during the build process and the Kotlin runtime version used at runtime.<\/p>\n\n\n\n<p>This error often happens when you are using a library or module that was compiled with a newer version of Kotlin than the one specified in your project&#8217;s dependencies.<\/p>\n\n\n\n<p>Update the Kotlin version specified in your project to match the version used during the compilation of the library or module. Open your <code>build.gradle<\/code> file and find the <code>kotlin<\/code> block.

Check their documentation or GitHub repository for compatibility information.<\/p>\n\n\n\n<p>If you are using any plugins or extensions in your project, ensure that they are compatible with the updated Kotlin version. Some plugins might require specific Kotlin versions to work correctly.<\/p>\n\n\n\n<p>Ensure that there are no conflicting Kotlin versions in your project. Sometimes, having multiple Kotlin versions from different dependencies can cause conflicts. Use the <code>.\/gradlew app:dependencies<\/code> command in your project&#8217;s root directory to check the dependency tree and verify if there are any duplicate Kotlin dependencies.<\/p>\n\n\n\n<p>If the error persists, try invalidating caches and restarting Android Studio.
