How do I best download the data I have collected with the Collector app and keep it synchronized as more data gets added to AGOL with the Collector app?
The tutorials were great but stop short of utilizing the collected data.
When you hit the sync button in Collector that will download any changes that do not exist in the database within the offline extent. So when data is pushed back up to AGOL other changes that exist on the service will be downloaded. You might want to do an additional sync on the devices once all the data has been uploaded to your service to make sure the app has the most up to date version of the data within the downloaded extent.
