Apps Unable initiate drag after 30 times drag event

Hi.I am able to create and drag and drop activity successfully but the only problem I faced is if I drag the view more than about 30 times, the drag event will stop to initiate and I am unable to drag anything. What is the causes?I am using onTouch() to drag the view.
