It would be great to be able to send push notifications to field users. This could be useful for dispersing information about new maps, surveys, and data as well as urgent communications and warnings. Having the ability to push a notification to a specific ArcGIS Online or ArcGIS Enterprise user would side-step having to email users about updates.
It seems like ArcGIS Companion would be a good option to accomplish this for the following reason.
- ArcGIS Companion can be installed alongside ArcGIS Collector, ArcGIS Explorer, or ArcGIS Survey123
- ArcGIS Companion already shows ArcGIS Online builtin notifications (such as group invitations, etc)
- The Python API for ArcGIS has the ability to create custom ArcGIS Online builtin notifications and send them to users or groups
If ArcGIS Companion could enable push notifications (to the lock screen or notification bar) for the ArcGIS Online builtin notifications, this could be a really useful way to communicate with end users of mobile workflows.
