Our SDKs include a synchronization feature to keep on-device collection bundles up to date.
“Sync” compares the collection on the device with the one stored in CraftAR and downloads the items that have been changed.
This method works on all our SDKs. However, at the moment it does not download the augmented reality contents. We recommend its use for image recognition or when the augmented reality contents are added programmatically.
We have articles for Android and iOS available where all the details regarding synchronization and tutorials on how to use it can be found.
