I'd check for two different jars containing the same class. I didn't get that specific error before about json, but I seem to remember the dalvik message.
Not sure if it would help, but I am curious what the entries are of your .classpath file in the project folder. You'll probably have the src/gen as src folders, but what, if any, "lib" entries do you have?
