+ * MapActivity is the abstract base class which must be extended in order to use
+ * a {@link MapView}. There are no abstract methods in this implementation which
+ * subclasses need to override and no API key or registration is required.

+ * A subclass may create a MapView either via one of the MapView constructors or
+ * by inflating an XML layout file. It is possible to use more than one MapView
+ * at the same time.
+ * <p>
+ * When the MapActivity is shut down, the current center position, zoom level
+ * and map file of the MapView are saved in a preferences file and restored in
+ * the next startup process.
