Google-play-services_lib Unable to resolve target 'android-9

Question

When I start up my Android ADT most if not all of my projects have a red exclamation next to them. And when I try to build and run them I get an error:

"google-play-services_lib] Unable to resolve target 'android-9'"

I am not sure what this means as I am up to date with my updates with my Android SDK manager.

I have tried restarting eclipse. I have tried downloading another Android SDK and running from there but still the same error.

Please help guide me into the right direction.

Actually downloading the latest ADT bundle for Eclipse gives the same error when trying to import the google_play_services_lib (17). http://developer.android.com/sdk/index.html#download

Open the SDK Manager, click obsolete (so API 9 shows up), and grab API 9. This is really something that seems like a simple oversight and should be fixed. Hope this helps others.
