hi, thanks for this script it helps a lot.
though it did failed for me.
it was missing the lib.rs file
and because there are no PRs for GISTs I forked it and made the modifications, feel free to use it
thanks again

Thanks @Nejat I went back and forth on this but ultimately decided not to overwrite in case someone used it on their existing project. I guess it won't overwrite if one exists so it shouldn't be a problem.

Thank you for creating this script! This is by far the easiest way to deploy to Android on the internet! Straightforward and precise!
