Xamarin Forms - Geofencing with Shiny not triggering when in geofence - xamarin.forms

Question

I have created a xamarin forms application and one of the requirements is as follows: The user should be able to press a button and create a geofence. When the geofence is created, the application constantly checks if the user is in a geofence. It that's true, the mobile app should show a notification sayinf: you have entered geofence.
I use Shiny to implement the feature based on this tutorial: "https://allancritchie.net/posts/shiny-geofencing".
But the problem is that it isn't doing anything. I have set the geofence 50 meters from my house, and the radius for checking to 200 meter, so when I build the app, a couple of seconds/minuts I should receive a nofitication right? Or do I need to go out of the fence first and then in? How can I fix this issue...
my code:
// shiny doesn't usually manage your viewmodels, so we'll do this for now
var geofences = ShinyHost.Resolve<IGeofenceManager>();
var notifications = ShinyHost.Resolve<INotificationManager>();
Register = new Command(async () =>
{
// this is really only required on iOS, but do it to be safe
var access = await notifications.RequestAccess();
if (access == AccessState.Available)
{
await geofences.StartMonitoring(new GeofenceRegion(
"CN Tower - Toronto, Canada",
new Position(52.079779, 4.337133),
Distance.FromMeters(200)
)
{
NotifyOnEntry = true,
NotifyOnExit = true,
SingleUse = false
});
}
});
public class GeofenceDelegate : IGeofenceDelegate
{
private readonly INotificationManager _notifications;
public GeofenceDelegate(INotificationManager notifications)
{
_notifications = notifications;
}
public async Task OnStatusChanged(GeofenceState newStatus, GeofenceRegion region)
{
if (newStatus == GeofenceState.Entered)
{
await GeofenceEntered(region);
}
else if (newStatus == GeofenceState.Exited)
{
await GeofenceLeft(region);
}
}
}
I have exactly the same code as the tutorial, and the geofence is created when I click a button if I debug it. So everything looks fine to me..

Answer 1

I had a similar issue and just assumed that when you start inside a fence it won't recognize you as entering/or exiting since you are already inside it.
I had to walk out/in of the created fence to trigger the 'OnStatusChanged' method.
Important to note is, that it wouldn't enter the method unless my app activated the phones GPS-system (e.g. re-requesting the current position periodically), but im not sure if that is caused by my old ass phone (running Android6.1) or if it is mend to work that way.
Also note, that i didn't use the shiny.notifications and just showed a popup when the method was run (for testing purposes) like this:
public async Task OnStatusChanged(GeofenceState newStatus, GeofenceRegion region)
{
await Application.Current.MainPage.DisplayAlert(newStatus.ToString(), $"{region.Identifier}", "Ok");
}
Hope this helps ;)
