It's good to see Aprijal getting back to Android builds after a busy period. I was not quick enough to share in time what he did last week but being late doesn't impact my queue and here i go!
The first release to mention is Brainfish 8 based on Stockfish 8. Aprijal's previous build was extremely voluminous in file size because it included the book. It worked okay for me as far as i could test and the engine played book moves regardless of the GUI settings.
However, i see that this time there's a separate book file to download and use with the engine. It's the default procedure used by some of the Android engines but not all of them can do this without problem even though they are supposed to do so under Android.
I've already heard about Brainfish 8 being unable to read the book when run with Chess for Android. I didn't test it myself, so i leave this to you. After all, Brainfish without book would be the same thing as standard Stockfish.
If you manage to make Brainfish use Cerebellum book with Chess for Android, just let me know.
