Feature Layer Feature Service

Demonstrates how to create a FeatureLayer from a ServiceFeatureTable and add it to an ArcGISMap.

How it works

To add Features from your FeatureLayer to an ArcGISMap.

  1. Create a ServiceFeatureTable from an URL.
  2. Create a feature layer from the service feature table.
  3. Set the feature layer to your ArcGISMap using ArcGISMap.getOperationalLayers().add(FeatureLayer).
