运行Android应用时出现ClassNotFoundException

Question

I'm trying to run the Spydroid app from . But run into a "Unfortunately Spydroid has stopped" as soon as it runs on my Nexus 4.

I used egit to grab a copy of the code into a new project in eclipse. At that point, it threw out a couple errors telling me to right click on the project and select Android Tools --> Fix Project Properties. I did as it said and then hit run, which uploads it to the Nexus 4, installs it and when it attempts to run is when I get the crash.

Am I doing something wrong in the checkout/setup process? I posted a similar post to the project's google code page
