Answering my own question,

After struggling for two days i found the answer.

Unity adds its own classes automatically to the project when building the application. If you bundle them with your library, they will get added twice, I resolved t$$anonymous$$s issue by using "exclude" and "provided" configurations in build.gradle

For a complete explanation for t$$anonymous$$s problem see t$$anonymous$$s link: https://stackoverflow.com/questions/34532008/error-building-android-library-for-unity-3d-5-3-android-studio
