A note for the above, it's all from a fresh install of kivy, buildozer as listed on the Ubuntu installation section of the kivy website.
Ubuntu 16.04

Thanks for the report. I've seen it, but I'm not sure offhand what is wrong. I'll try to look into it.

It was a python-for-android versioning issue I got from pip. After installing the newest one from the python-for-android master branch, I was able to get past that step.

Going to close this issue, since this ticket is specific to that problem, but FYI the entire buildozer build process is full of strange "Build failed", but if you run them manually then sometimes they work, sometimes they don't. Maybe it's time to go from start-to-finish for an example kivy app built for android using nothing but the documentation of the Kivy website and these projects, and see if any problems that may be easy fixes come up. It might be refreshing.

Cheers.
