Xamarin.Android error XA0116
Issue
Xamarin.Android's build process extracts various EmbeddedResource
files from its assemblies during a build. These include internal Java
source files that are required for a Xamarin.Android application to
start successfully. A XA0116 error would only be encountered if one
of these required files is missing.
