A problem with the WP for android instructions

Hi,
I'm following the guide and I'm stuck.
I made it till page 21. Before that, on page 19, I had an issue - eclipse did the "search and replace" for me after I changed the folder name... I hope it's OK.
Ok, so I got to page 21, and now when I try to run the program, it says:
"Your project contains error(s). Please fix them before running your application".
I see around 928 errors in the messages panel...
Can you please shed some light over this?
Thanks,
Yonatan
