After a rainy Sunday afternoon in front of my PC, jCheckers is now available! For some reason, I had to rewrite the entire GUI because NetBeans wasn't creating a proper distribution output for my jCheckers project. At least I also learned how to write callback functions in Java (with Interfaces), and implemented one for communication between the JCheckerBoardPanel and the main window. I should also implement one for the communication between the checkers engine and the JCheckerBoardPanel - but since my Java checkers engine is shared between Android and the full Java program, I was a bit reluctant to touch it. In fact, the engine isn't properly shared between the two because of some differences between Android and standard Java. My programmer friends tell me I should use dependency injection, but that will have to wait!
In the meantime, you can enjoy jCheckers on Linux and Mac, where CheckerBoard isn't available. jCheckers has a powerful Java checkers engine, multiple levels of play, PDN support, and unlimited takeback through the game.
Since I don't own either Mac or Linux computers, I'd be glad to get feedback on whether it runs on these systems as it should.
