Service feature table (Cache)

Sample viewer app

Display a feature layer from a service using the on interaction cache feature request mode.

Use case

Service feature tables support three request modes, which define how features are requested from the service and stored in the local table. The feature request modes have different performance characteristics. Use On interaction cache in scenarios with large amounts of infrequently edited data. See Table performance concepts in the ArcGIS Runtime SDK for Android guide to learn more.

How to use the sample

Run the sample and pan and zoom around the map. With each interaction, features will be requested and stored in a local cache. Each subsequent interaction will display features from the cache and only request new features from the service.

How it works

  1. Set the ServiceFeatureTable.setFeatureRequestMode(...) property of the service feature table to ON_INTERACTION_CACHE before the table is loaded.
  2. Add the table to the map using a FeatureLayer; features will be requested for the visible extent as the user pans and zooms.

Relevant API

  • FeatureLayer
  • ServiceFeatureTable
  • ServiceFeatureTable.setFeatureRequestMode

About the data

The sample opens with an initial visible extent centered over pool permit statuses in California.

Additional information

On interaction cache is the default feature request mode. Features are requested automatically for the visible extent as the users pans and zooms the map. If the user returns to an area where features have previously been requested, those features won't be requested again.
