send touch events to a device via adb [duplicate]

Answer 1

Android comes with an input command-line tool that can simulate miscellaneous input events.
To simulate a tap, use:

input tap x y

Run the input command remotely using adb shell:

adb shell input tap x y

Other options are:

shell@m0:/ $ input
input
usage: input ...
       input text <string>
       input keyevent <key code number or name>
       input [touchscreen|touchpad|touchnavigation] tap <x> <y>
       input [touchscreen|touchpad|touchnavigation] swipe <x1> <y1> <x2> <y2> [duration(ms)]
       input trackball press
       input trackball roll <dx> <dy>

Answer 2

To send touch event you need to do:

1 Set coordinates:

adb shell sendevent /dev/input/event2 3 0 x
adb shell sendevent /dev/input/event2 3 1 y

2 Send touch event (must have 0 0 0 pair):

adb shell sendevent /dev/input/event2 1 330 1
adb shell sendevent /dev/input/event2 0 0 0

3 Send release finger event (must have 0 0 0 pair):

adb shell sendevent /dev/input/event2 1 330 0
adb shell sendevent /dev/input/event2 0 0 0

Please note:

1 You can record events:

adb shell getevent

2 if you use getevent all event values are in hex.

Answer 3

You might want to use monkeyrunner like this:

$ monkeyrunner
>>> from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice
>>> device = MonkeyRunner.waitForConnection()
>>> device.touch(200, 400, MonkeyDevice.DOWN_AND_UP)

You can also do a drag, start activies etc. Have a look at the api for MonkeyDevice.

Answer 4

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
