I am getting the following error
Error 183 The type 'Android.App.ListActivity' is defined in an assembly that is not referenced. You must add a reference to assembly 'Mono.Android, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.
I am running MonoCross 1.3, the latest versions of Xamarin and the Android SDK, and Visual Studio 2012. I tried looking on Google for the issue, but couldn't find anything helpful.
