# There are three shells: the host's, adb, and termux. Only adb lets us run
# commands directly on the emulated device, only termux provides a GNU
# environment on the emulated device (to e.g. run cargo). So we use adb to
# launch termux, then to send keystrokes to it while it's running.
# This means that the commands sent to termux are first parsed as arguments in
# this shell, then as arguments in the adb shell, before finally being used as
# text inputs to the app. Hence, the "'wrapping'" on those commands.
# There's no way to get any feedback from termux, so every time we run a
# command on it, we make sure it ends by creating a unique *.probe file at the
# end of the command. The contents of the file are used as a return code: 0 on
# success, some other number for errors (an empty file is basically the same as
# 0). Note that the return codes are text, not raw bytes.

"Usage: $0 COMMAND [ARG]
where COMMAND is one of:
snapshot APK install APK and dependencies on an emulator to prep a snapshot
(you can, but probably don't want to, run this for physical
devices -- just set up termux and the dependencies yourself)
sync [REPO] push the repo at REPO to the device, deleting and restoring all
symlinks (locally) in the process; by default, REPO is:
$this_repo
build run \`cargo build --features feat_os_unix_android\` on the
device, then pull the output as build.log
tests run \`cargo test --features feat_os_unix_android\` on the
device, then pull the output as tests.log
If you have multiple devices, use the ANDROID_SERIAL environment variable to
specify which to connect to."
