I finally got decent build instructions for linux on my repo wiki here. If someone has an idea of how to improve, let me know, or add it. 
They include how to download QT6 from the internet, and follow to running QtAOG on a desktop to creating .apks on android.
I also got .apk’s created for both QtAOG and QtAgIO. They’re not really useful yet, but look kind of neat. Android use in the field has a ways to go yet. The two programs idea will have to go, or get seriously redone. Not being able to see both QtAOG and QtAGIO at the same time is a real pain. And we need the correct code to allow a program to run in the background. APKs are on google drive if anyone is interested. QtAOG Binaries. - Google Drive
For now, android isn’t really the main thrust. Debugging is a pain, so there’s no point in really trying to get it to work until QtAOG works well on a computer OS. Then we’ll focus more on android.
I’d like to hear from someone who has built QtAOG on windows! The build instructions should be fairly close to linux, but could vary slightly.
