So Pak0St and I both got Anbox working earlier. One of the Librem guys shared his aarch64 Android image (for me) I put it into /var/lib/anbox/ and it just worked. The app drawer/manager came up, several apps have worked fairly well so far.
EDIT: I don't recommend using the German site I linked earlier to add GLES 2.0 support. After adding that the build.prop, and dropping the image into /var/lib/anbox the app drawer became a black box, or would immediately crash when trying to open an app. I just removed it and replaced the image, but it still isn't working properly anymore. I'm going to dial it back, and try adding just wifi and bluetooth to the available features to start. Maybe we can get networking going.
EDIT2: I don't think I would recommend altering the image at all at this point. I've been removing things from the enabled features section out of anbox.xml and rebuilding the image, but it's still very unuseable. Nearly ever app crashes it. I've since restored the original (working) android.img and things are still slow, but useable. I also tried following the Networking section of the Arch wiki for Anbox (since that's where all of this REALLY came from) but the files/locations don't align with the install. Instead, I ran ' anbox-bridge' to try and get system network shared to Anbox. The output was riddled with Permission denied's looking for things like sudo and openvpn-client, so I ran it again with sudo and it completed it's task.
