hi luben, I try to use zstd-jni (1.5.2-3) lib in my android project in Android studio IDE, so I import this lib with gradle like: dependencies { ..... implementation "com.github.luben:zstd-jni:1.5.2-3@aar" testImplementation "com.github.luben:zstd-jni:1.5.2-3" ..... }

run the android test in my phone, the following error message:

This looks something new, in the aar we have a build for arm64-v8a. Do you know what is arm64-v8l? When it was introduced? Is it compatible with v8a?

armv8l seems to be Cortext-A32: ARMv8.0-A, 32-bit only.

UPD armv8b is also 32 bit, big-endian, though I've never seen such devices

Hmm, I guess I have to update my Android studio, or mess with the config to enable that target
