MapView - how to zoom to the viewport returned by the GeoCode service

Issue

When I receive a geocode response from the GeoCode service from Google, it contains a recommended viewport describe as Lat/Lng pairs.

How can I zoom in/out to the recommended viewport ?

Solution

The answer to this problem is to use MapController.zoomToSpan(...). Find the difference between the North/East coordinates and the South/West coordinates and then call the zoomToSpan method.
