Can anyone explain why this code doesn't work on Android?

Question

I wrote this code to demonstrate a way to detect swipes left and right and it works fine on iOS but doesn't seem to work for Android users. Can anyone explain why?

Answer 1

its interesting how different it is.

usually to take touch coordinates i need to take the array-like touch object from the event, the reason for that is multitouch.
ex.
swipedown = e.touches[0].pageX

we also cant directly take the coordinates from the touchend, because the array-like object is empty by then. and so touchmove event were used to update the touch position, that can be use later in touch end

Answer 2

Could also use e.changedTouches[0].pageX

Taste Great answer, thank you!

Would it be possible for you to build a small working demo to show how it needs to be done for Android? I wouldn't normally ask but, obviously, I'm unable to test it myself.
