Create a new example application in the android-sdk repository that uses the android-sdk-framework dependency and implements all requirements. The app must be Kotlin. Deserialization/parsing/serialization/JSON libraries must be based on kotlinx.serialization. HTTP must be done by OkHttp 4.x. The app demonstrates using BaseAndroidClient by building a KotlinxConfigurationParser (using kotlinx.serialization JsonElement) and wiring it together with OkHttpEppoClient. The example app must compile and run on Android.
