 유니티3D 안드로이드 프로젝트를 이클립스에서 빌드 중 위와같이 에러가 발생했습니다.

 libmono.so는 유니티가 사용하는 lib 파일이죠. 유니티3D에서 빌드했다면 이상 없었을텐데 이클립스를 메인으로 빌드하면 이 파일을 찾기 때문에 임포트한 UnityPlayerProxyActivity 프로젝트의 assets/libs 디렉터리를 개발중인 이클립스 프로젝트의 assets 디렉터리에 복사합니다.

 그리고 assets/bin 디렉터리도 Unable to locate player settings. bin/Data/settings.xml 에러에 대비해서 복사해줍니다.
