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?

Hi,
The SubLayers for an operation layer depends on the type of the layer you are using. For example, ArcGISMapImageLayer will have the sublayers where as a FeatureLayer does not.

Here is a sample that demonstrates querying sublayer information from an ArcGISMapImageLayer,

Hi RamaChintapalli,

How about the sublayer is feature layer?

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
