如何解决 “invalid resource directory name”, resource “crunch”

Ant and the ADT Plugin for Eclipse are packing the .apk file in a different build chain and temp generation folders. Crunch is created by the ADT. Best to do is to start every step with a clean if you switch between the tools. use ant clean if you used the ADT from eclipse before. UseProjects -> clean ... in Eclipse if you used ant before. Hope this solves your problem. Also restarting Eclipse could help.
