This is Xamarin Bug 32498
The problem starts when you usually install one of the Xamarin.Android.Support packages . * nuget.
Then the IDE (VS2015 for me) freezes and nothing works, so you are forced to disable the IDE. After reopening the IDE and forcing a link to the assembly, as well as creating the project, he says:
android.support. *
:
:
Xamarin.Android.Support. * # Google ( JAVA), google ( Xamarin #: Java).
