Introducing Map View and Map Activity

This section introduces several classes used to support Android maps:

> MapView is the Map View control.

> MapActivity is the base class you extend to create a new Activity that can include a Map

View. The MapActivity class handles the application life cycle and background service management required for displaying maps. As a result you can use Map Views only within

MapActivity-derived Activities.
