I'm at a standstill in Eclipse due to an "Android Library Update" that never finishes. I tried restarting Eclipse, restarting my computer, deleting the .metadata folder under my Eclipse workspace, and several other shots in the dark. Under Window -> Preferences, I also already checked "Skip packaging and dexing (...)"
I have only two projects open: a small demo app and the Google Play Services Library linked to it. So the problem can't be too many projects, per this question.
Does anybody have any other ideas?
