Nullpointer exception while Dragging and Dropping

Open sarfarazmadhia opened this issue 10 years ago • 2 comments

Please see the Crash Trash. I believe, when adapter.notfydatasetchanged is called and that time when we try to Drag and Down, It causes Crash. As i would like to refresh my views by a asynchronous Task and also allow Dragging and Dropping of items.
