Listmaker app keeps stopping

Hello everyone! I am trying to work on the listmaker app from the android apprentice book and when I try to run the app, the app keeps stopping. I have done this app 9 different times and the message is the same. What do I need to do to get around this? I am running a galaxy nexus simulater, plus I have a samsung tablet connected. Please help!

What message do you get and What is the problem?
