Xamarin Studio updater does not check Android SDK for updates.
I haven't upgraded my Android SDK in the entire time I've been using the platform. I'm looking now and think I'm seeing that some of the feature gaps I've been noticing have been because I haven't been keeping my Android SDK updated. Maybe this is something the Xamarin Studio update checking should keep on top of in some way... warnings about "Hey, did you know there's a new Android SDK available?" straight from the same Xamarin IDE
