Might be related to https://github.com/chrisbanes/PhotoView/issues/31, was thinking can fix this by adding a try catch to SwipeHelper.OnTouch() Any ideas would be great!

Also have this issue

[dmllr]

This happened when user touches the screen using more than one fingers and first touch was outside of swipestack view.

In

    mPointerId = event.getPointerId(0);
    mDownX = event.getX(mPointerId);
    mDownY = event.getY(mPointerId);

should be used correct touch index (that inside of view), instead of 0.

Or simply disable swiping when touches are outside of view.
