## Two options for where the lbry-android source code comes from:
##  1) Clone directly from git via provided VERSION and REPO environment variables.
##  2) User may mount their own lbry-android source tree at /src
## Only one of these two options can be used at a time.
## VERSION is any valid git reference: commit, branch, or tag.
## REPO is the git repository URL to clone.

## User must create their own buildozer.spec and google-services.json
## This may be done in their own fork of lbry-android,
##   or done in their own clone mounted to /src
