I'd a similar problem with the build on Android Studio, but my DllNotFoundException: MonoPosixHelper was with using System.IO.Compression

https://assetstore.unity.com/packages/tools/integration/gzipstream-deflatestream-unity-io-compression-31902 This asset solved it, maybe it will be useful some one else.

The missing jar file makes any sense? Are you using ,like me, the native library already existing on Unity? A jar library sounds to me like a custom helper library, which i presume this is not our case.
