I have a Sony Xperia M and installed CyanogenMod a couple of times. When ever I want to download GAPPS, I wonder, if my Smartphone is ARM or x86, and when ever I google it and don't find an answer, I have a deja vú and I just go with ARM since it is most common and my phone is probably ARM.
But shouldn't there be a way to find out?
adb shell getprop ro.product.cpu.abi gives you the hardware answer (e.g. "arm64-v8a" for my Wileyfox Swift).adb shell uname -m tells you what the kernel is running (e.g. "aarch64" for the same device)If you do not have ADB setup (and don't plan to), you can run the same commands in a terminal app. Just skip the preceding adb shell then:
$ getprop ro.product.cpu.abi
arm64-v8a
$ uname -m
aarch64
$
