Does these versions contain armv7 ? not only Arm64v8 because i cant find it.

64 bit version only.

Dear Archimedes,
I really ask you not to support the support of the younger versions of Android and compile please engines for all architectures (Armv7, Arm64. x86, x86_64).
I have on Android 5.1 (ARM64 MT6735 4 kernels of 1300 MHz) the latest versions of the ShashChess and BrainLearn engines are no longer launched.
But, my friend on Android 10 (ARM64 Snapdragon 845 8 Nuclei of 2800 MHz) These engines work.
My last work assembly is ShashChess 18.2 for all architectures. This assembly works on Android 5.1 ARM64, on Android 4.4.2 Armv7 and for Android 4.3 x86.
BrainLearn engine operating assembly found version 12.1 with built-in neural vehicles, on other versions were dead links with App.Box.com.
Sir Archimedes, now no one except you do the compilation of engine drives under android, so be kind to us holders android 4 and Android 5.
Please make an archive with the assembly engine and for Armv7, x86 and x86_64.
Health to you and success in life!

Most of the chess engines are compiled with Android NDK (see jni directory in zip archives). I always use the latest official release of Android NDK for that job. I always used API level 21 for 64 bit and API level 16 for 32 bit versions. The newest version of Android NDK do not support non neon devices anymore. Therefore, the lowest possible API level for 32 bit devices are now 19. This conservative values (the lowest possible API levels) should work on most Android devices. However, older devices without neon support are no longer supported anymore. And you need a not too old Android version (see API levels). What i want to say, is, i already use conservative values for maximum compatibility, but keep in mind i must also take care for performance. I try to take care both sides of the medal (compatibility and performance). I can't make everybody happy.

BrainLearn and ShashChess are compiled with the CECSA (Chess Engine Compiler Script for Android) script for Termux. At the end, they are compiled with g++ with their (modified) makefiles. The libcurl library is included in the executable for maximum compatibility. Only 64 bit version available.

Dear Archimedes,
Thank you for your reply ! I ask for the future, if you can always make compilation of engines for all architectures (ARM64, ARMv7a, x86, x86_64).
If you have an old compilation of the BrainLearn engine for all architectures or (ARMv7a + ARM64) after version 12.1, then I ask you to post in this topic.
About ShashChess - I will use the version 18.2 - it works great on Android 5.1 ARM64.
I apologize for the concern and bad English (I use the Google translator).

I will make a small contribution to the filling the theme engines for Android. Found Godel Chess Engine V 7.0 dated 24.02.2020g.
I have only a file for Armv7a on Android 5.1.
My friend for Android 10 runs the file for ARM64.

Tucano version 10.00 release with neural network evaluation, should be significant stronger than version 9.00.

Dear Archimedes,
Thanks for the Tucano engine 10.00 for all architectures!
Launched without a neural network - it works.
Dear Gua Gapapa,
StockFish engine is the most versatile in terms of compatibility, but your compilation does not work on Android 5.1 ARM64.

Do I care? I'm just learning to compile my own chess engine, it works or not on your device I don't care about that

It's okay to collect chess engines, but don't be too obsessed, playing chess is just a distraction for me, because real life like school or work is more important

Can you please test, wether one of the following builds are working on your device.

Then BrainLearn, compiled with Android NDK, should also work.

Maybe could you compile also Koivisto 7.10 with NDK to try to solve Chess for android 6.2.1 compatibility issues?

Thank you dear friend!

Alex

Dear Archimedes,
BrainLearn 15.2 Android NDK works great on android 5.1. The engine began to weigh 4 times less ! Great job Sir Archimedes ! Thank you from the bottom of my heart !

Koivisto is already compiled with Android NDK.
