The ArcGIS Mobile SDK includes a set of Geometry components that you can use to create and update the shape of features, perform spatial selections, and draw graphics on the map display. The geometry components are responsible for handling the shape of features stored in a map or a local mapca cache . Geometry types available in the Mobile SDK include Point, Multipoint, Polyline, Polygon and Envelope. This topic briefly discusses how geometry is managed with the ArcGIS Mobile SDK and then illustrates how to use it with numerous examples.
