[Android] BuildMethodException (2017.3.1, IL2CPP)

After adding `<assembly fullname="Nethereum.Unity" preserve="all"/>` node to `link.xml` I've got this build error. No human-readable message. What does it mean, how to solve?

Code (csharp):

@Yury-Habets Are there any estimates when Unity is stable and usable? Should I try 2018.1 beta, or there are no chances build process is fixed there?

 

I see nothing like that.

That's the issue.

I cannot upload log file via “Upload a File” button: “The uploaded file does not have an allowed extension. Editor-1.log”. Let me try Pastebin... https://pastebin.com/raw/E0Kb5ktL

 

After some manipulations (like reimporting, removing `Library/`, restarting, etc.) I've got another log-file. The error is the same, no human-friendly message again, but contains more details somewhat related to IL2CPP. (Again: everything works fine in case of Mono+Android or IL2CPP+Editor; the problem reveals in case of IL2CPP+Android. If entry in `link.xml` is not added, then build is fine, but runtime error related to stripping arises.)

Looks like same types like `BigInteger` are compiled to different (hence incompatible) C++ types, depending on which assembly they are referenced from.

Please let me know if something becomes clear or workaround is found. Maybe the issue is fixed in newer versions; any ETA for Unity 2018 non-beta?
