Building a Flutter Android app with klippaidentityverificationsdk 0.2.12 fails during project configuration with this error. Gradle 8.0+ (Android Gradle Plugin 8) requires every library module to declare an android namespace, and the SDK's android/build.gradle did not set one, so configuration of ':klippaidentityverificationsdk' throws "Could not create an instance of type LibraryVariantBuilderImpl ... Namespace not specified". A manual subprojects override for the namespace led to a follow-on Kotlin jvmTarget error.
