This article adds: Many online gesture articles say that Android supports gestures only from SDK 1.6 (that is, API 4), but I can also identify them using SDK1.5 simulators !. (I wanted to test the support effects of lower sdks, but I didn't have

The Vector class provides the function of increasing the number of groups. As more elements are added to the group, the number groups become larger. After deleting a few elements, the number groups become smaller. Vector has three structure
