This page shows you how to render geographic data in the KML
format, using GMUKMLParser in
conjunction with GMUGeometryRenderer. KML is a popular
format for rendering geographic data such as points, lines, and polygons.
The following screenshot shows some example KML data rendered on a map:
For the full code sample, see the sample apps
on
GitHub.
Rendering KML data
To render KML data on a map, create a GMUKMLParser with the
path to a KML resource (KML_Sample.kml in this example). Then,
create a GMUGeometryRenderer passing the GMUKMLParser
instance. Finally, call GMUGeometryRenderer.render(). The
following code example shows rendering KML data on a map:
