Tasks are the foundation of the geospatial functionality in your Android applications. Using tasks in your application, users can interact with maps, find and display reports of real-world objects, collect geographic information and analyze what is seen on a map.

Tasks are wrappers around operations supported by ArcGIS Server REST web services. Tasks take care of asynchronously sending the request, showing the network activity indicator, applying appropriate credentials to the network resource, and parsing the results.
