Polyglot for Android

Image
There was an interesting discussion on the TalkChess forum whether a chess GUI running on the Dalvik Virtual Machine could merely support a single protocol, and use an adapter, like Polyglot, to support other protocols. Even though Chess for Android already supports both UCI and XBoard/WinBoard, I was intrigued by the question, and decided to give it a try. First, I compiled the polyglot sources for ARM-based Android devices (I had to make a few source changes to make that work). Then I edited a polyglot.ini file pointing to my own UCI engine bikjump1.8 compiled for ARM:
[Polyglot]
EngineCommand=bikjump1.8
EngineName=BikJumpAsXBoard
EngineDir=/data/local/tmp/
[Engine]

And gave it a try directly from the command line:

$ ./polyglot_for_android

Temporary Chess Server

Image
As a follow-up on the previous posting and for users that want to experiment with a remote chess server without setting one up themselves, I have, very temporarily, set up a remote chess server with various engines at ports 2000 through 2005 on aartbik.dyndns.org. Simply type this hostname and one of the ports in Chess for Android and let me know if you were able to connect!
