INSTALL_FAILED_CPU_ABI_INCOMPATIBLE with ARMv6 device

[GlassGruber]

Hei there,
I've tried install the APK file via ADB on a old 2.3 device, but unfortunately the install command results in an error as in title INSTALL_FAILED_CPU_ABI_INCOMPATIBLE.

By running this command adb shell cat /proc/cpuinfo the relevant returned info is below

Processor       : ARMv6-compatible processor rev 5 (v6l)

I realize ARMv6 is very old so I don't know if it's feasible at all to produce a compatible APK, and I don't know how common was for Android 2.3 devices to be ARMv6 back in the day.

Thank you for your time!

Hi, and yes, ZXingCpp, the native barcode scanning library this app is using, isn't built for ARMv6, unfortunately 🙈

I'm using my own fork of it, so in theory it should be possible to build a compatible APK. Although that would require a very old version of Android's NDK, too, which may or may not work (probably NDK r8e or earlier, which isn't even available in the Android NDK Archives anymore 😬).

So it may be possible if we can find NDK r8e, and if this can compile my ZXingCpp fork 🤔

Unfortunate but predictable, I can't tell if it's really worth the effort...
Thank you for your answer!
