Simple solitaire game.
Currently documentation is limited but I will add comments to the source and detail the structure in here.
I do not use eclipse so I can't really guarantee that it will build in that environment.
First off you need to download the SDK from http://code.google.com/android. Once installed you need to modify solitaire's build.xml file to include the path to the SDK (Two lines near the top). Then running ant should complete the job. If you have difficulties, try building a sample program from code.google.com first which has a bunch of detail and troubleshooting info.
