Xamarin.Android绑定从Go生成的AAR-如何处理元组返回?

I try to create a Xamarin.Android-Bindings Project for the following AAR: https://jcenter.bintray.com/io/storj/libuplink-android/0.6/

It basically works. But the problem is that the included Java code got generated from Go-Code and it seems that all functions returning a tuple are not included in the binding. See this function: https://github.com/storj/storj/blob/057d30152c80847a4edb0e7e91c31b012108b6ff/mobile/uplink.go#L65

This gets generated.

But the following does not (as it returns a tuple?): https://github.com/storj/storj/blob/057d30152c80847a4edb0e7e91c31b012108b6ff/mobile/uplink.go#L44

Is this something a can overcome by specifying something in the metadata.xml? Anything else I can do?

Thank you!
