Yes - it doesn't mean, though, that your Android device does allow access
to the way we want to access that device :-(

Interesting. What are the differences to the others? What's its model
number?

I tend to use Qt Creator on Linux or macOS. Native building under Windows
isn't supported at all. Creating the Android binaries is easiest done
using our hand crafted docker build container. You can look at our Travis
instructions for Android to see how you can do that.

Check the files in subsurface/scripts/android

No, that's not it at all...

I need to add code to have these dive computers listsed on Android
devices. I'll do that in a moment and maybe I can just tether through my
phone and upload the binaries. Then you'll be able to install this via the
Google Play Beta channel for Subsurfae-mobile.

Fingers crossed you'll have something there in a few hours.
