Hi Esri team,
In our current app setup, we use GeodatabaseSyncTask to download individual layers from a feature service for offline use. However, we’ve noticed that this approach does not preserve the custom symbology configured in ArcGIS Online — it only retains the default symbology defined in the feature service.
We understand that OfflineMapTask can be used to preserve symbology, but it requires downloading the entire Web Map, which doesn’t fit our architecture or workflow.
We’d like to kindly propose the following improvement:
Allow downloading a single layer with its custom ArcGIS Online symbology, without requiring a full Web Map.
This feature would be especially useful for apps that:
Do not use Web Maps, but rely on base map styles (BasemapStyle);
Need flexibility to work with independent layers;
Aim to preserve the visual fidelity of custom renderers configured online.
We’re aware that it’s currently possible to use .stylx files and DictionarySymbolStyle, but assembling all the required components manually increases development complexity and risk.
Thank you for considering this idea. It would be a very helpful enhancement for developers using the ArcGIS Maps SDK in offline workflows.
