Usage: adb_remote_setup.sh REMOTE_HOST [REMOTE_ADB]

local machine. This is useful for installing APKs, running tests, etc while
working remotely.

Arguments:
  REMOTE_HOST  hostname of remote machine
  REMOTE_ADB   path to adb on the remote machine (you can omit this if adb is in
               the remote host's path)
EOF
  exit 1

remote_host="$1"
remote_adb="${2:-adb}"

# Ensure adb is in the local machine's path.
if ! which adb >/dev/null; then
  echo "error: adb must be in your local machine's path."
  exit 1
fi

if which kinit >/dev/null; then
  # Allow ssh to succeed without typing your password multiple times.
  kinit -R || kinit

# Kill the adb server on the remote host.
ssh "$remote_host" "$remote_adb kill-server"

# Start the adb server locally.
adb start-server

# Forward various ports from the remote host to the local host:
#   5037: adb
#   8001: http server
#   9031: sync server
#   10000: net unittests
#   10201: net unittests
