Hi, how do I perform a three finger tap with appium? I want to perform the three finger tap 3 times.

My current code looks like this:
# Set up coordinates for the taps if needed, or find an element to tap on
x1, y1 = 850, 450 # Coordinates for first finger
x2, y2 = 900, 450 # Coordinates for second finger
x3, y3 = 950, 450 # Coordinates for third finger

    # Create TouchAction instances for each tap
    tap1 = TouchAction(self.driver).tap(x=x1, y=y1)
    tap2 = TouchAction(self.driver).tap(x=x2, y=y2)
    tap3 = TouchAction(self.driver).tap(x=x3, y=y3)

    # Create a MultiAction object
    multi_touch = MultiAction(self.driver)
    multi_touch.add(tap1, tap2, tap3)

    # Perform the multi-touch action (the triple tap)
    multi_touch.perform()
    multi_touch.perform()
    multi_touch.perform()

However, I’m encountering this error:

It is worth noting, that I don’t see any errors when I run multi_touch.perform() just once.

Touch Actions are deprecated

Any example code snippets? I’ve tried updating my code to use PointerInput, but still have issues witha triple touch tap…

    # Set up the pointer input devices (one for each finger)
    finger1 = PointerInput(PointerInput.POINTER_TOUCH, "finger1")
    finger2 = PointerInput(PointerInput.POINTER_TOUCH, "finger2")
    finger3 = PointerInput(PointerInput.POINTER_TOUCH, "finger3")

    # Coordinates for each finger tap
    x1, y1 = 935, 450
    x2, y2 = 1135, 470
    x3, y3 = 1335, 480

    for _ in range(3):  # Repeat the gesture three times
        action = ActionBuilder(self.driver)

        # Create actions for each finger
        action.add_pointer_input(
            finger1, finger1.create_pointer_move(x=x1, y=y1, duration=0)
        )
        action.add_pointer_input(
            finger1, finger1.create_pointer_down(PointerInput.POINTER_TOUCH)
        )
        action.add_pointer_input(
            finger1, finger1.create_pointer_up(PointerInput.POINTER_TOUCH)
        )

        action.add_pointer_input(
            finger2, finger2.create_pointer_move(x=x2, y=y2, duration=0)
        )
        action.add_pointer_input(
            finger2, finger2.create_pointer_down(PointerInput.POINTER_TOUCH)
        )
        action.add_pointer_input(
            finger2, finger2.create_pointer_up(PointerInput.POINTER_TOUCH)
        )

        action.add_pointer_input(
            finger3, finger3.create_pointer_move(x=x3, y=y3, duration=0)
        )
        action.add_pointer_input(
            finger3, finger3.create_pointer_down(PointerInput.POINTER_TOUCH)
        )
        action.add_pointer_input(
            finger3, finger3.create_pointer_up(PointerInput.POINTER_TOUCH)
        )

        # Perform the actions
        action.perform()
        print("performing triple tap")
        sleep(0.1)  # Wait for a short duration between gestures

I think you want to use ‘tap’ method here:

Thank you!, I was able to get multi-touch working with ‘tap’.

   coords = [(935, 450), (1135, 470), (1335, 480)]

    for _ in range(3):
        self.page_utils.tap_location(coords)
        print("Performed triple tap.")
