WMTS services can have several layers. You can use Runtime to explore the layers available from a service. This would commonly be used to enable a browsing experience where users can choose which layers they want to display at run time.
How to use the sample
Pan and zoom to explore the WMTS layer, which is displayed automatically.
How it works
Create a WmtsService using the URL of the WMTS Service.
After loading the WMTS service, get the list of WmtsLayerInfos from the service info: service.getServiceInfo().getLayerInfos()
Use one of the layer infos to create a new WmtsLayer(layerInfos.get(0))
Set it as the maps' basemap with map.setBasemap(new Basemap(wmtsLayer)).
