I just installed Eclipse and Android SDK in Mac OS X.
I imported the project to Eclipse and i get the Unknown command \'crunch\' error while running the project.
Updating Android SDK Tools to r14 and Android SDK Platform-tools to r8 also solved this problem for me.
I had to check 'Installed' in the SDK Manager in order for the updates to be listed (even though I had the previous versions already installed). Checking only the New/Updates box meant they wouldn't show up in the list.
