Use case

Sometimes users may want to edit features in an online feature service by moving them.

How to use the sample

Tap a feature to select it. Tap again to set the updated location for that feature.

How it works

  1. Create a ServiceFeatureTable object from a URL.
  2. Create a FeatureLayer object from the ServiceFeatureTable.
  3. Select a feature from the FeatureLayer, SelectFeatures.
  4. Load the selected feature.
  5. Change the selected feature's location using Feature::setGeometry(Geometry).
  6. After the change, update the table on the server using applyEdits.
