I'm building a Xamarin app and for the geolocation, I'm using the GeolocatorPlugin

The problem is that once the code wants to get the position, the code exists without warning.

My class fields:

private Position position;
private IGeolocator locator = CrossGeolocator.Current;

My page constructor:

public MainPage()

 InitializeComponent();

 locator.PositionChanged += Locator_PositionChanged;
 locator.PositionError += Locator_PositionError;

OnAppearing event is calling the getLocationPermission:

 private async Task GetLocationPermission()
 
 var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.LocationWhenInUse);
 if (status != PermissionStatus.Granted)
 
 //Not granted, request permission
 if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.LocationWhenInUse))
 
 // This is not the actual permission request
 await DisplayAlert("Need your permission", "We need to access your location", "Ok");
 

 // This is the actual permission request
 var results = await CrossPermissions.Current.RequestPermissionsAsync(Permission.LocationWhenInUse);
 if (results.ContainsKey(Permission.LocationWhenInUse))
 status = results[Permission.LocationWhenInUse];
 
 //Already granted, go on
 if (status == PermissionStatus.Granted)
 
 //Granted, get the location
 GetLocation();
 await GetVenues();
 await locator.StartListeningAsync(TimeSpan.FromMinutes(30), 500);
 
 else
 
 await DisplayAlert("Access to location denied", "We don't have access to your location.", "OK");
 
 

The permission is granted and gets to the GetLocation() method:

 private async void GetLocation()
 
 //var locator = CrossGeolocator.Current;
 try
 
 var myPosition = await locator.GetPositionAsync();
 position = new Position(myPosition.Latitude, myPosition.Longitude);
 
 catch (Exception ex)
 
 throw;
 
 if (position == null)
 
 //Handle exception
 
 

Once the line is reached with locator.GetPositionAsync(), it stops. No exception is thrown, also the PositionError isn't raised.

I have no idea why, but in the beginning it worked once, never worked after that.

The location settings in de Android Emulator are as follow:

Based on my research, you did not acheved that Location Changes like this link

I wrote a demo about Location changes. This is running screenshot.
