Answer 1

Fixed this issue by:

1. Cleaned Solution
2. Deleted projects /bin and /obj folders
3. Deleted Android.Support.Design, Android.Support.v7.RecyclerView and zips folder in path ~/.local/share/Xamarin/
4. Rebuild project

That's it. This forced Xamarin Studio to download and unzip the Android support files again correctly. Will take some time since needs to download the packages, should fix the issue after that.
