I have Several Feature Service Layers inside Feature services and when I add Feature services to Map view using following method 
ArcGISFeatureLayer secureFeatureLayer = new ArcGISFeatureLayer(Feature_Service_url, MODE.ONDEMAND);
its Layers does not show up in Map view.
But when  I add individual Feature Service Layer  it does show the layer details correctly.
So My question is to add Feature services do I have to add its Layers one by one or is there any other ways to add Feature Service directly to Map view?
