Questions about geodatabase feature attachments

[ShiminCai]

Hi All,

We are using AGSGeodatabaseSyncTask to generate offline geodatabases. In the generated geodatabase we don't want to include existing feature attachments. To do this, we set the AGSGenerateGeodatabaseParameters.returnAttachments = false.

My first question is: am I able to add attachments to the features in the generated geodatabase?. Here is my post about the issue a few years back: https://community.esri.com/t5/arcgis-runtime-sdk-for-ios-questions/offline-geodatabase-attachments/m...

My second question is: how do I determine if a layer is enabled with attachment capability? Because we set AGSGenerateGeodatabaseParameters.returnAttachments = false, I have noticed that the AGSArcGISFeatureTable.hasAttachments is always false even though the feature layer in the feature service is already enabled with attachment...

Thanks,

Shimin

Hi All,

We figured it out:

1. set AGSGenerateGeodatabaseParameters.returnAttachments = false to not include existing attachments.

2. set AGSGenerateGeodatabaseParameters.attachmentSyncDirection = AGSAttachmentSyncDirection.upload.

3. AGSArcGISFeatureTable.hasAttachments will be true if the layer in the feature service is enabled with attachment.

Then we are able to add attachment to features offline.

Cheers,
