It looks like there were some changes with the resources in Nougat 7.0, so if you're targeting Nougat or you have the v24 libraries from Xamarin the build will fail because some resources that are in the BottomNavigationBar do not exists anymore.
I think it's only a thing of updating the referenced Xamarin libraries.
Took me a couple of hours trying to figure what was exactly the problem though.
