mouseup mousedown mousemove를 touch로 바꿨는데 IOS에서는 되는데 안드로이드에서는 작동이 않됩니다.
어디를 고쳐야 안드로이드에서도 작동이 될지요?


<script>
var carousel = $('#carousel1'),
    threshold = 150,
    slideWidth = 90,
    dragStart,
    dragEnd,mflag=0;

$('#slidenext').click(function(){ shiftSlide(-1) })
$('#prev').click(function(){ shiftSlide(1) })

  $(document).on('touchend', function(){
    mflag=0;

  carousel.off('touchend');

  carousel.off('touchmove').removeClass('transition');
 
  $(document).off('touchend');
  })

carousel.on('touchstart', function(){
mflag=1;

  if (carousel.hasClass('transition')) return;
  dragStart = event.pageX;
  $(this).on('touchmove', function(e){  
    dragEnd = e.pageX || e.originalEvent.touches[0].pageX;
    $(this).css('transform','translateX('+ dragPos() +'px)')
  })
  $(document).on('touchend', function(){
    if (dragPos() > threshold) { return shiftSlide(1) }
    if (dragPos() < -threshold) { return shiftSlide(-1) }
    shiftSlide(0);
  })
});

function dragPos() {
  return dragEnd - dragStart;
}

function shiftSlide(direction) {
  if (carousel.hasClass('transition')) return;
  dragEnd = dragStart;
  $(document).off('touchend')
  carousel.off('touchmove')
          .addClass('transition')
          .css('transform','translateX(' + (direction * iw) + 'px)');
  setTimeout(function(){
    if (direction === 1) {
      $('.slide:first').before($('.slide:last'));
    } else if (direction === -1) {
      $('.slide:last').after($('.slide:first'));
    }
    carousel.removeClass('transition')
carousel.css('transform','translateX(0px)');
  },700)
}
