Glad i'm back again from busy working days, at least for the weekend.
On a previous post dated Nov,2nd, i'd written about the OEX installer app by Javiolo coming with Stockfish 8 builds.
That app included only the PIE builds, therefore users of Android prior to 4.1 could not use them.
As the alternative app from the same developer comes with noPIE builds, now the whole Android range is covered.
You may install Stockfish 8 OEX installer from GOOGLE PLAY.
In case you need the standalone engine binaries, choose below:
GET Stockfish 8.0.JV for 32-bit arm5 nopie
GET Stockfish 8.0.JV for 32-bit arm7 nopie
GET Stockfish 8.0.JV for 32-bit x86 nopie
In case of difficulties downloading from box, refer to THIS POST.
