continuous touch on the screen using ADB shell

Question

I want to keep the camera button pressed to take continuous snaps. I tried this code:

#!/system/bin/sh
am start -n com.android.camera2/com.android.camera.CameraLauncher
sleep 1
count=1
x=2
while [ $count -le 1 ]
do 
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
    input touchscreen tap 560 1800
done

But it does not hold the button. It taps with a delay.

Then I tried this:

 sendevent /dev/input/event0 3 53 300
 sendevent /dev/input/event0 3 54 400
 sendevent /dev/input/event0 3 48 5
 sendevent /dev/input/event0 3 58 50
 sendevent /dev/input/event0 0 2 0
 sendevent /dev/input/event0 0 0 0
 sleep 1
 sendevent /dev/input/event0 0 2 0
 sendevent /dev/input/event0 0 0 0

this code gets executed but the effect is not seen on the touchscreen

This is the second code i tried . due to some reason the code is not indented properly sendevent /dev/input/event0 3 53 300 sendevent /dev/input/event0 3 54 400 sendevent /dev/input/event0 3 48 5 sendevent /dev/input/event0 3 58 50 sendevent /dev/input/event0 0 2 0 sendevent /dev/input/event0 0 0 0 sleep 1 sendevent /dev/input/event0 0 2 0 sendevent /dev/input/event0 0 0 0 — user3659556, May 22 '14 at 03:05
there is no common solution to your question. Devices have different /dev/input definitions. If you have the rooted device, you can use internal API of WindowsManager to inject events at Java level. — Jiang YD, May 22 '14 at 04:00
your second attempt looks like the code from my answer here https://stackoverflow.com/a/17263093/1778421 - why didn't you go to the page linked in that answer? — Alex P., Dec 05 '17 at 19:56

This will work adb shell input swipe 660 2200 660 2200 5000

The last value is duration

You can swipe and hold with 'input motionevent'

input motionevent DOWN x y
input motionevent MOVE x y
input motionevent UP x y

"this code gets executed but the effect is not seen on the touchscreen"

try "adb shell su -c 'YOUR COMMAND'"

it helped me. if you send a command without su, then the code will not answer anything

There is workaround for this, You can use swipe for long press: "adb shell input swipe 560 1800 560 1800 "
