The TileView widget is a subclass of ViewGroup that provides a mechanism to asynchronously display tile-based images for the Android mobile-application development framework, with additional functionality for 2D dragging, flinging, pinch or double-tap to zoom, adding overlaying Views (markers), built-in Hot Spot support, dynamic path drawing, multiple levels of detail, and support for any relative positioning or coordinate system.
