Notepad Tutorial Android - menu problems

I am working on the Notepad Tutorial on the Android dev site, part 1. I have done all the code as in the tutorial, also tried with开发者_高级运维 the code form the downloaded solution. When i launch the app I don't see a button "Add note", and therefore I cannot continue with the tutorial. It seems like the methods aren't firing?

All i see is title and the note that says "there are no notes here yet".

Thanks so much for any help!
