I've been looking around and I finally got the full source code for a game 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 are there errors?

Likely you are missing libraries that need to be defined. And you may want to slow down a bit, find something simpler first. –  Byte56 Mar 22 '12 at 21:38
    
Do you recomend anything simpler? Something more exciting than tetris? Plus, isn't changing an open-source code suppose 2 be easy and for practice? It seems to me that the only hard part of an open-source code is setting it up. –  Blue Mar 22 '12 at 21:56

Nope, it's not supposed to be easy, and typically it's difficult. I don't know of anything else you can switch to, it's just my recommendation. –  Byte56 Mar 22 '12 at 21:58
    
Well I'm just trying to set it up so I can run it, then I can change it. Like adding new features or or removing settings i wouldnt like. –  Blue Mar 22 '12 at 22:11

Send the developer a few euros (more than two) and an email asking for help setting up Eclipse with his project. Support open source and get the exact help you need. WIN-WIN.

AppleCrunch is based on Rokon which I think is not maintained anymore. Rokon is based on LibGDX which is very actively maintained. My advice is stick with LibGDX. An alternative is AndEngine but I found the lack of documentation sickening when I was a beginner so I chose LibGDX, but the choice is yours.

this was an open-source project that used rokon instead of libgdx. I'm not that experienced so I don't how to change the library without having to change the coding. In the future I plan to use LibGDX. –  Blue Mar 23 '12 at 11:42
