Geodatabase class final

A mobile geodatabase containing geographic data and non-spatial tables.

Geodatabase is used to open and access the contents of a mobile geodatabase (.geodatabase file) that can contain geographic features, non-spatial tabular data, and data such as attachments, utility networks, field domain definitions, contingent values, and relationships between layers/tables.

Geodatabases can contain one or more geodatabase feature tables. You can create a layer from a GeodatabaseFeatureTable tables, as follows:

A FeatureLayer from any table returned by Geodatabase.geodatabaseFeatureTables that contains point, polyline, or polygon features. Check that FeatureTable.hasGeometry is true.
An AnnotationLayer from any table returned by Geodatabase.geodatabaseAnnotationTables.
A DimensionLayer from any table returned by Geodatabase.geodatabaseDimensionTables.

You can generate a mobile geodatabase file from an ArcGIS feature service and downloaded it to a device using offline workflows offered by the GeodatabaseSyncTask and the OfflineMapTask. Apps can then operate offline to view and edit the features in these geodatabases. If the geodatabases are enabled for synchronization with the original feature service, edits can be synchronized when connectivity is restored.

Mobile geodatabase files can also be created with ArcGIS Pro. These geodatabases can be used offline but they do not support synchronization with the original feature service. See Build offline applications for more information.
