Description Shay 2017-03-17 04:20:55 UTC
I can't compile my Android app anymore in release mode.
I get the following error:

/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets: Error: Error executing task LinkAssemblies: error XA2006: Could not resolve reference to 'System.Void Android.App.Activity::OnMultiWindowModeChanged(System.Boolean)' (defined in assembly 'Xamarin.Android.Support.Fragment, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null') with scope 'Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'. When the scope is different from the defining assembly, it usually means that the type is forwarded. (ClimbTag.Droid)
