@AndersonNoleto - You may need to uninstall Xamarin Forms from your Android Project, along with all the other Android.XXX packages.
Then just install Xamarin Forms, it will install the other packages by default. Don't upgrade these other packages though.
Then run your project and see if you get the same error. You may need to restart Visual Studio as well, after you have installed the Xamarin Forms nuget again.
