readme.md

1) Know the event name of touchpad :

Run :

adb shell getevent -pl

Search for : "ABS_MT_TRACKING_ID" - example :

add device 2: /dev/input/event5
  name:     "mtk-tpd"
  events:
    KEY (0001): KEY_W                 KEY_E                 KEY_U                 KEY_O
                KEY_S                 KEY_L                 KEY_Z                 KEY_V
                KEY_M                 KEY_UP                KEY_LEFT              KEY_RIGHT
                KEY_DOWN              KEY_MENU              KEY_BACK              KEY_HOMEPAGE
                KEY_SEARCH            BTN_TOUCH
    ABS (0003): ABS_X                 : value 0, min 0, max 720, fuzz 0, flat 0, resolution 720
                ABS_Y                 : value 0, min 0, max 1280, fuzz 0, flat 0, resolution 1280
                ABS_PRESSURE          : value 0, min 0, max 255, fuzz 0, flat 0, resolution 0
                ABS_MT_TOUCH_MAJOR    : value 0, min 0, max 100, fuzz 0, flat 0, resolution 0
                ABS_MT_TOUCH_MINOR    : value 0, min 0, max 100, fuzz 0, flat 0, resolution 0
                ABS_MT_POSITION_X     : value 0, min 0, max 720, fuzz 0, flat 0, resolution 0
                ABS_MT_POSITION_Y     : value 0, min 0, max 1280, fuzz 0, flat 0, resolution 0
                ABS_MT_TRACKING_ID    : value 0, min 0, max 10, fuzz 0, flat 0, resolution 0

As you see, event5 is responsible for Touchpad

2) Record events

2.1 run :

adb shell
$ su
$ cd /mnt/sdcard
$ cat /dev/input/event5 > events

2.2 Make your move! swipe or touch ... it's your game

you can stop recording by pressing Ctrl+C

2.3. Play your recording

to play your events, run

$ cat events > /dev/input/event5 

Tada.. That's it! this method is zeroing the timeval ! No delay

The other method is to use x and y coordinates

adb shell input swipe [X1] [Y1] [X2] [Y2] [duration(ms)]

Example :

adb shell input swipe 500 630 714 722 100

The Problem is adb shell input swipe is so slow

Hi Adem, thanks for you tips on recording events in Android with Adb.
I can record events and play then, but only one at a time.
Is it possible to record and run a series of events?
Thanks

@Caballero75 Thank you ♥
please take a look

Hi Adem, your guide is working like a charm, thanks for the tips! The recorded event is executed very fast, do you know if there's a way of doing it a little bit slow?

@gabriel7771 Thank you so much ❤️
I don't know if there is a method how to make it slow

Easier way to record and play back: https://www.repeato.app
There is a free version too.

Delicious for a 'doubleclick' event

Thanks a bunch
