Android 2.2 SDK - Android Camera app missing import android.hardware.Camera.CameraInfo

I pulled down the latest source from GIT for the camera app, but android.hardware.Camera.CameraInfo seems to be missing when it's imported (and messing the rest of the app up). I tried changing from And开发者_StackOverflow中文版roid 2.2 to Google APIs 2.2, but that didn't do anything. What am I missing here?

According to the docs, this is available since API level 9, i.e. Android 2.3.
