This is a build taken from Stockfish forum chat. I don't know who has done it but once loaded the ID showed 120616 which i assume to be correct. It seems the source is very recent but keep in mind that generating a good Android build needs many tricks and take the unknown with some caution.
Shortly said, i don't have enough info to guarantee that this mysterious build delivers more power than Peter Österlund's latest release. It's made for arm7 32-bit and may not work on Lollipop and Marshmallow. Try and see for yourself: HERE
