I just posted v2.0 of Chess, Checkers, and Reversi for Android at the Android Market with the following improvements: => Small, normal, and large screen size support. => Full screen board layout. => On screen buttons moved to menu. => Unified trackball cursor. => More levels of strength. In addition, chess has been improved with: => Choice of two chess piece sets. => Rotating board.

Her is a preview of the upcoming Chess for Android on a small, normal, and large screen. The full screen is used for the board layout. It also uses a new chess set, designed by my sister Elisabeth (awesome job, thanks!). Other upcoming improvements include board rotation (so that the player can see the pieces from the perspective of either white or black), a choice in chess sets, and an enhanced menu (rather than mixed on-screen and menu buttons).

While preparing my applications for the wider variety of screen sizes, I also eliminated the title bar and "wooden" border in favor of a larger board size. Especially in landscape mode and for the upcoming smaller screens, this will hopefully enhance the playing experience. As a preview, a screenshot of Reversi for Android before and after shown below (ignore the stuff on the right for now; that is subject to change too). Checkers and Chess for Android will change similarly.

It has been a long while since I published The Software Vectorization Handbook but occasionally I get an email on the topic. Recently someone asked me whether I could make the examples in the book available electronically. Luckily, I found all examples in my older archives, and I posted code samples on my website.

Up to now, my Android applications assume a fixed screen size (HVGA 320x480) and, although portrait and landscape views are supported, the code that implements board layout is not general enough to deal with all sorts of screen sizes. Android is designed to run on a variety of devices with different screen sizes and resolutions, however, and starting with version 1.6 , multiple screen sizes should be handled. Just for fun, I tested how my applications would run on various screen sizes. The screen shot for reversi is shown below. As expected, I have some work to do to make my applications more compliant with the latest extensions. This also may give me an excuse to implement some of the other requested features (such as rotating the board when playing black in chess).
