I'm in the process of designing a mobile Xamarin app and would like to know if both iOS and Android devices can monitor GPS in the background for geofence entry/exit, and then ping my web servers via REST API.
The app will be run in the background by truck drivers, and their dispatcher will receive a notification on their web-based dashboard when the truck driver enters a particular geofence.
I am looking at the CrossGeeks API as of now, but have no preference which one to use.
All of the samples I've found online send push notifications OnEntry or OnExit. None have examples or mentions of sending updates to a server.
My question is: Can I use the GeoFencing API to wake up my app that's running in the background and send a notification to my server that it's entered a particular geofence?
Thanks in advance.
