How to use ADB to send touch events to device using sendevent command

Question

I am trying to send touch events to a device using AndroidDebugBridge  so that I can do some basic automation for UI tests  I have followed the discussion in LINK  I am able to use sendevent to simulate touch on emulators  but unable to do the same on a device    Like in above link the emulator seems to send out 6 events for each touch   xcoord  ycoord  2 for press 2 for release  and it was easy to use this information to sendevents  but a getevent for the touchscreen for a device seems to generate far too many events   Has somebody managed to send touch from ADB to a device  Could you please share the solution

Consider using Android s uiautomator  with adb shell uiautomator       or directly using the  jar that comes with the SDK

Building on top of Tomas s answer  this is the best approach of finding the location tap position as an integer I found   adb shell getevent -l   grep ABS MT POSITION --line-buffered   awk   a   substr  0 54 8   sub   0        a   b   sprintf  0x s  a   printf   d n  strtonum b       Use adb shell getevent -l to get a list of events  the using grep for ABS MT POSITION  gets the line with touch events in hex  and finally use awk to get the relevant hex values  strip them of zeros and convert hex to integer  This continuously prints the x and y coordinates in the terminal only when you press on the device   You can then use this adb shell command to send the command   adb shell input tap x y

You don t need to use      adb shell getevent -l   command  you just need to enable in Developer Options on the device  Show Touch data  to get X and Y    Some more information can be found in my article here  https   mobileqablog wordpress com 2016 08 20 android-automatic-touchscreen-taps-adb-shell-input-touchscreen-tap

In order to do a particular action  for example to open the web browser   you need to first figure out where to tap   To do that  you can first run   adb shell getevent -l   Once you press on the device  at the location that you want  you will see this output    lt     gt   dev input event3  EV KEY       BTN TOUCH            DOWN  dev input event3  EV ABS       ABS MT POSITION X    000002f5  dev input event3  EV ABS       ABS MT POSITION Y    0000069e   adb is telling you that a key was pressed  button down  at position 2f5  69e in hex which is 757 and 1694 in decimal   If you now want to generate the same event  you can use the input tap command at the same position   adb shell input tap 757 1694   More info can be found at   https   source android com devices input touch-devices html http   source android com devices input getevent html
