Apply scheduled updates to preplanned map area

Apply scheduled updates to a downloaded preplanned map area.

Use case

With scheduled updates, the author can update the features within the preplanned areas on the service once, and multiple end-users can request these updates to bring their local copies up to date with the most recent state. Importantly, any number of end-users can download the same set of cached updates which means that this workflow is extremely scalable for large operations where you need to minimize load on the server.

This workflow can be used by survey workers operating in remote areas where network connectivity is not available. The workers could download mobile map packages to their individual devices and perform their work normally. Once they regain Internet connectivity, the mobile map packages can be updated to show any new features that have been added to the online service.

How to use the sample

When the sample loads, it will display an offline map, check for available updates, and show update availability and size. Tap the button to apply the updates to the local offline map and show the results.

How it works

1. Create an OfflineMapSyncTask object with your offline map.
2. Get an OfflineMapUpdatesInfo instance from the task to check for update availability and update size.
3. Get the default OfflineMapSyncParameters from the task.
4. Set the parameters to download all available updates.
5. Use the parameters to create an OfflineMapSyncJob object.
6. Start the job and get the results once it completes successfully.
7. Check if the mobile map package needs to be reopened and do so if necessary.
8. Display the updated offline map to see the changes.
