Using the MapView in android, how can I set a default location, so that everytime I load up this application, it automatically centers/zooms location in on London?
Firstly, get the controller for the given map:
MapController myMapController = myMapView.getController();
and then call:
myMapController.setCenter(new GeoPoint())
This will set the center of the map on the given GeoPoint.
See docs for MapView and MapController for more info
