Stockfish Android ((BETTER))

I've cheated against cheaters before. They pause near the end, as if to wonder how their s**tty engine lost when I'm using stockfish. I imagine they're some non-playing idiot using a crappy engine they found on their Nintendo switch or something.

Stockfish 13, released February 19, 2021, is the strongest chess engine at the moment I am writing these lines. You can download it for windows, linux, mac os, and also android. Yet at the moment I am writing these lines, the android binaries download link points to Stockfish 12 and not 13. (This happens often with Stockfish, as the android binaries are not the ones people need the most.) As Stockfish is open source (github here), how could we cross-compile Stockfish 13 on a windows 10 computer for an Android phone ? (In my case, a Samsung Galaxy S21 Ultra running Android 11.)

We are going to need the source code : git clone -stockfish/Stockfish.git (see the right address at Stockfish's github as this address could change) somewhere on your PC. (You need the command line utilities of Tortois Git for instance.) Let's call StockFishDIr the full path to the StockFish folder (that contains src as subfolder) on the PC.

(Note that there was the initial android21 in the CXX line that I replaced with android30. It is because the Samung Galaxy s21 Ultra runs Android 11 whose real version number is android30. If you have an android phone with another android version, adapt the lines consequently.)

When the preceeding command executes properly it produces the stockfish_13_armv8_xcomp_win10x64 binary inside the StockFishDIr\src folder. This binary is already usuable on you phone (by putting it inside the DroidFish\uci folder of your DroidFish app, for instance) but is not optimal as the size is big and the execution is a little bit slow. Hence we have to "strip" the binary with the following command line, still inside the StockFishDIr\src folder :

In Droidfish, open the left menu, find the Engines management submenu, pick the stockfish_DEV_armv8 binary, and in the configuration menu adjust its UCI parameter settings. Depending on the CPU power of your device and the available memory, you should probably give it more than the default one Thread, and more than the default 16 MB of Hash memory. A good start would be to try 2 Threads, and 512 MB for the Hash tables, and see if you can beat it ? e24fc04721
