Chess for Android 10 Year Anniversary!

I can't believe it, but Chess for Android just passed its ten year anniversary! In November 2008, it appears for the first time on the -then-called- Android Market, together with Reversi for Android. Checkers for Android was soon to follow. The Android Market was later renamed Google Play.
Working on this GUI has been a lot of fun, even though it took all spare time away from further developing my chess engine BikJump. But pioneering support for third party engines (at a time nobody was compiling for ARM), both UCI and XBoard, accessing endgame tablebases on SD card, adding PGN and setup features,simplifying engine setup through Chessbase compatible format and the Android Open Exchange format, using OCR apps to read chess positions, translating text to other languages, maintaining an online manual, and recently adding support for Certabo, DGT, and Millennium electronic chessboards has been just as rewarding. I have compiled many engines for Android back in the days, ran full tour…

Chess for Android: Certabo Support

Besides the Millennium and DGT, Chess for Android now also supports the Certabo electronic chessboards. I hope to roll out a next update soon, after more rigorous testing.

Unlike the other boards, the Certabo board does not necessarily come with chess pieces. Instead, a set of 34 identifying chips is provided, which can be attached to the bottom of pieces in any chess set (which means that, unlike the other board, the GUI must first match newly attached chips with the right pieces).
Since I did not have a spare set, I asked my brother-in-law, Gerard Harbers, who just bought a fancy new 3D printer, to print a full chess set for me. He enthusiastically got to work!

The pieces have some spare room at the bottom, perfect for placing the identifying chips.

Lots of New Features for Chess for Android.

Recently I have been very active adding new features to Chess for Android again. I have added support to connect to the Millennium ChessGenuis Exclusive electronic chessboard, added a new piece set (thanks Bryan Whitby), added various engine related features requested by users, and switched to the much better model where users can enable (and thus disable) permissions just for the features they like.
Now, I also added optional piece animation and algebraic notation on the board. Hopefully this makes watching ongoing tournaments more smooth, as illustrated below for a match between Komodo and DiscoCheck. Keep an eye on Google Play for updates!

Animation of Engine Moves

Because it is hard to print all information from the UCI engine on the phone screen, I am toying with a feature where the current move considered by the UCI engine is shown graphically. Below is a short demo of this feature. Let me know what you think!

Animation on Android

I wrote my first animation on Android! It is actually part of a simple screen tester, where I can inspect the screen size of a device and see different font sizes, colors, and text positions. For fun, I added three moving balls (the circles in the screenshot below), all bouncing between the four screen borders.
