Dragging in Android

I updated the OnEndDrag as below. Added Input.GetTouch(0).fingerId This now works on android but is broken on PC. Would be great if someone has an agnostic solution to this.

void IEndDragHandler.OnEndDrag(PointerEventData eventData)
        {
            transform.position = startPosition;
            GetComponent<CanvasGroup>().blocksRaycasts = true;
            transform.SetParent(originalParent, true);

            IDragDestination<T> container;
            if (!EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
            {
                container = parentCanvas.GetComponent<IDragDestination<T>>();
            }
            else
            {
                container = GetContainer(eventData);
            }

            if (container != null)
            {
                DropItemIntoContainer(container);
            }


        }

Here’s my attempt at making this platform agnostic:

void IEndDragHandler.OnEndDrag(PointerEventData eventData)
        {
            transform.position = startPosition;
            GetComponent<CanvasGroup>().blocksRaycasts = true;
            transform.SetParent(originalParent, true);


            IDragDestination<T> container;

#if UNITY_EDITOR
            if (!EventSystem.current.IsPointerOverGameObject())
            {
                container = parentCanvas.GetComponent<IDragDestination<T>>();
            }
            else
            {
                container = GetContainer(eventData);
            }
#elif UNITY_ANDROID
            if (!EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId))
            {
                container = parentCanvas.GetComponent<IDragDestination<T>>();
            }
            else
            {
                container = GetContainer(eventData);
            }    
#else
            if (!EventSystem.current.IsPointerOverGameObject())
            {
                container = parentCanvas.GetComponent<IDragDestination<T>>();
            }
            else
            {
                container = GetContainer(eventData);
            }
#endif

            if (container != null)
            {
                DropItemIntoContainer(container);
            }


        }
