Cannot setup binding. Could you help me?

Trying to setup binding to library. This library (jar) references 4 .so libraries. So, I cant understand what I need to do. Current solution, that doesnt works: - UnityClasses library is wrapper around classes.jar (InputJar build type), which contains 2 packages and with 4 .so libraries with AndroidNativeLibrary build type. - XamarinTest project is monodroid startup project. References UnityClasses, classes.jar (as AndroidjavaLibrary build type) and 4 .so libraries as EmbeddedNativaLibrary build type).

Error: executing task BuildApk: An element with the same key already exists in the dictionary

Could you help me setup it correct, please?

Thanks
