I've been looking around and I finally got the full source code called Apple-Crunch from google code. But when I put it into my project, the source code included so many errors in the class files such as:

• cannot be resolved into a type
• the constructor is undefined
• the method method() is undefined for the type Sprite class.java

I downloaded the source directly from the command-line and noticed errors popping up on my project. Since i couldn't figure out how to import the actual folder into my workspace(it wouldn't show up on existing projects) I decided to copy and overwrite the folders into the project. The Errors were still there so I looked at the class files and noticed that the classes with errors extended from 'RokonActivity'. I then proceeded to add to the libs folder the rokon library in hopes to fix the errors. Sadly it didn't work and now I don't what to do to fix the errors.

How do i fix the errors without having to manually change the code? The source code should be fully functional so why is there errors?
