Want to retrieve a list of layers and sublayers

BTDS_GISAdmin

I am using the SDK 100.10.0. When I tried to using to list the layer and the sublayer it has. However, it is always show 0 for sublayer. I know some layer has sublayers. 

 

for(Layer layer: map.getOperationalLayers()){
   Log.i(TAG, layer.getName());
   Log.i(TAG, layer.getSubLayerContent().size());
}

 

 What is the correct way to retrieve the sublayer info?

Sample ArcGISMapImageLayer URL: 
https://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/MapServer

Sample FeatureLayer URL: 
https://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/FeatureServer/0

Here is the hierarchy,

Map
    - Operational Layers 
           -  ArcGISMapImageLayer
                         - ArcGISMapImageSubLayer - ServiceFeatureTable
           - FeatureLayer
                         - ServiceFeatureTable

A feature layer cannot have another feature layer as a sublayer. However you can create a FeatureLayer from an ArcGISMapImageSubLayer's table since both of them can be backed by a ServiceFeatureTable.

Thanks
