I recently uploaded my project to Git, and used a auto-generated Xamarin/Windows/MacOS/VisualStudio .gitignore file. I did a lot of work and testing on iOS, but now I'm coming back to android but upon building the Project.Droid version, I get the following errors:

Error   11  Please install package: 'Android Support Library' available in SDK installer. Android resource directory C:\Users\dev\AppData\Local\Xamarin\Android.Support.v4\21.0.3\embedded\./ doesn't exist.    MyProject.Droid

Does anyone know how can I fix it? I checked my SDK Manager using admin rights and I already have the Android Support Library installed
