Eclipse Android: not found class

I am doing the following tutorial on building an Android application using the Google App Engine: https://cloud.google.com/developers/articles/how-to-build-mobile-app-with-app-engine-backend-tutorial

I use Eclipse on Windows 7. I ended up in the part where you run the application to display recently downloaded information from "places.csv". The problem is that I get the following error:

Also in debug mode, I get a "Source Not Found" error in Thread [<1> main].
