    Unless I'm missing something really hacky and tricky that we could do, I don't see any way to implement this in Android. We get the scroll event easily thanks to Android View.onScrollChanged. For our TableView, we can get scrollEnd easily thanks to Android ListView.setOnScrollListener, the listener for which contains onScrollStateChanged, which can be checked for SCROLL_STATE_IDLE. But for non-ListView scrollers such as the ScrollView, this doesn't exist.

    Hacky solutions like maybe checking for the first touch UP event after a onScrollChanged event -- meaning the user has lifted their finger after a scroll -- wouldn't take into account that the view still may be flinging, and also wouldn't account for a scroll caused by the trackpad.

    In short, I can't think of any way to do this. Any ideas out there in Donland?

    Moving to M05 to see if I can find away around it.

    There is some discrepancy about what this event is suppose to do. It appears that it was put in iOS to deal with pull for refresh. Android doesn't have "overscroll" until API 9. Moving to TBS until we can resolve what the event is suppose to do on both platforms.
