NoClassDefException, starting activity from another package

Question

This is my first time using Eclipse ADT, and I'm having trouble starting a new action from another package. I try to run com.furgus.cam.CameraActivity from com.furgus.swipe.LobbyActivity , but I keep getting NoClassDefFoundError from the crash for the correct CameraActivity binding. I'm not quite sure what I'm doing wrong, and I really need guidance.

We will be very grateful for any help. Thank you
