How do I get the extents for all sublayer?

jackcrawford

I'm new to the Java runtime. I'm trying to get the extent for each sublayer which I assumed would be available by calling 

getMapServiceSublayerInfo().getExtent() 

butgetMapServiceSublayerInfo()

always returns null.

I've tried with our map service and the ESRI sample service 

http://sampleserver6.arcgisonline.com/arcgis/rest/services/USA/MapServer

Guidance would be much appreciated.

Hi Jack: You are explicitly loading the `ArcGISMapImageLayer` but not the sublayer.
