[Q] GOGOC apk

Hi all,
Since my network does not support IPV6 I was looking for a tunnel client for my android phone.
I've found a client, but it is just released in source code mode. I'm talking about the https://github.com/liudongmiao/gogoc-android project.
Does anybody knows if there is an apk or zip file in order to install the client?

Thanks

Leo
