You don't need to tweak Makefiles or anything like that. Once you follow those steps you can get and armv8 APK with

ANDROID_ARCH=arm64 ./kodev release android

Release APK are unsigned, so they will fail to install. You need to sign them with your own keys. There're plenty of tuturials online.

Thats where I started. Doesn't work, at least not on my system anyway. Following those instructions without any changes always only produced armeabi-v7, never armv8. Happy to be told I am doing something wrong, but I cannot imagine what it might be.

If useful, I can start the whole process again and write down every step with relevant output logs. But, it would essentially be the instructions in the two links followed by "oops, thats not armv8"

The makefile changes I made finally did produce armv8, and yes I signed the apk to get it to install. But once installed, the application constantly crashes. Some adb logcat output is included in my original message.

@mergen3107 --- good to know that debug releases are signed. Will make it easier with repeated builds as I try to get this sorted out! Thanks!
