send touch events to a device via adb [duplicate]

Answer 1

I managed to record a session and replay it with only bash and adb.

This what I did, I hope it helps someone.

Record a series of events

1. Set up the pc to record data in a file (/tmp/android-touch-events.log)

   $ adb shell getevent | grep --line-buffered ^/ | tee /tmp/android-touch-events.log
   

2. do some stuff on the phone
3. stop the adb command on the pc with ctrl-c

Replay the recorded events

This command will do the hex conversion in awk

$ awk '{printf "%s %d %d %d\n", substr($1, 1, length($1) -1), strtonum("0x"$2), strtonum("0x"$3), strtonum("0x"$4)}' /tmp/android-touch-events.log | xargs -l adb shell sendevent
