Hi, We have not yet provided an official tutorial for xamarin android. It is possible that the repository you have linked contains errors, even if we were unable to reproduce them in our tests.
Anyway we advise you to wait for the official tutorial to be released or try converting the tutorial written in java at this link.
Best,
