# Pair the phone's workout_app with this PC's workout poke listener.
|
|
#
|
|
# Creates ~/.config/workout_poke/key if missing (workout_poke_keygen.sh), then
|
|
# hands it and the PC's LAN address to the app over adb via its
|
|
# PairPcReceiver broadcast, which stores both in the Android keystore. Success
|
|
# is decided by the broadcast's own reply -- `adb shell` exits 0 even when
|
|
# the receiver is missing -- so it needs both `result=-1` and `data="paired"`.
|
|
#
|
|
# The key is on adb's command line for the broadcast's lifetime (that is the
|
|
# receiver's interface) but is never printed.
|
|
#
|
|
# Usage: pair_phone.sh [--sandbox] [--host IP] [-s SERIAL]
|
|
# --sandbox pair the sandbox flavor (com.kuhy.workout_app.sandbox)
|
|
# --host IP the PC address the phone should poke (default 192.168.1.43)
|
|
# -s SERIAL passed to adb when several devices are attached
