유니티 오류가 복잡해 보이지만 해결 방법은

unity-plugin-library.jar 이 파일 찾아서 지워주면 됩니다.

추가로

\Assets\Plugins\Android\GoogleMobileAdsPlugin

폴더를
\Assets\Plugins\Android\GoogleMobileAdsPlugin.androidlib
이렇게 바꿔주면 됩니다.

java.lang.RuntimeException: java.lang.RuntimeException: Duplicate class com.google.unity.ads.AdNetworkExtras found in modules googlemobileads-unity-runtime.jar (:googlemobileads-unity:) and unity-plugin-library.jar (unity-plugin-library.jar)
