I'll admit up front, I'm not an android developer, and this is my first time using CF (so maybe I have a setting checked that shouldn't be). I was pulling my hair out trying to figure out this SDK thing until I came to this thread, so that's one problem solved. Is this something CF will be addressing (if anyone knows), the removal of the ant folder by google.
