I have some problems with my bing maps.
The first one happens when I click on My Location - from almost all locations I were it worked fine, but there are some locations that returns null, why? (It happened me in a new building that hasn't address yet and also happened in a building with no internet connections).
The method:
private async void MyLocation_Click(object sender, RoutedEventArgs e)
{
Bing.Maps.Location location = await GeoLocation.GetCurrentLocationAsync();
MapLayer.SetPosition(_flagPin, location);
map.SetView(location, 15);
}
The first line calls to my static function:
public static async Task<Bing.Maps.Location> GetCurrentLocationAsync()
{
Geolocator geo = new Geolocator();
geo.DesiredAccuracy = PositionAccuracy.Default;
Geoposition currentPosition = null;
currentPosition = await geo.GetGeopositionAsync();
return new Bing.Maps.Location()
{
Latitude = currentPosition.Coordinate.Latitude,
Longitude = currentPosition.Coordinate.Longitude
};
}
What is the problem? How to fix it?
And the second question is about addresses. When I get an Address object, there are many formats I can select such as FormattedAddress, CountryRegion, PostalTown, I selected The FormattedAddress and there is a problem with it.
My code:
GeocodeResponse GP = await GeoLocation.ReverseGeocodeAsync(location.Latitude, location.Longitude);
EventContext.Address = GP.Results[0].Address.FormattedAddress;
The problem is when I want to send an Address and get the Location. Sometimes this code returns null, why?
GeocodeResponse GP = await GeoLocation.GeocodeAsync(EventContext.Address);
I thought that maybe the problem is that sometimes the Address (Formatted) is not good, sometimes it gives weird addresses, such as, "Street, st. Canada", which is not found and therefore, it returns null. But what can I do to send a correctly Address? Does FomattedAddress is good?
Here are the two GeoCodeAsync
and ReverseGeocodeAsync
functions:
public static async Task<GeocodeResponse> GeocodeAsync(string address)
{
GeocodeService.GeocodeRequest geocodeRequest = new GeocodeService.GeocodeRequest();
// Set credentials using a Bing Maps key
geocodeRequest.Credentials = new GeocodeService.Credentials();
geocodeRequest.Credentials.ApplicationId = Application.Current.Resources["BingCredentials"] as string;
// Set the address
geocodeRequest.Query = address;
// Make the geocode request
GeocodeService.GeocodeServiceClient geocodeService = new GeocodeServiceClient(GeocodeServiceClient.EndpointConfiguration.BasicHttpBinding_IGeocodeService);
GeocodeResponse geocodeResponse = await geocodeService.GeocodeAsync(geocodeRequest);
return geocodeResponse;
}
public static async Task<GeocodeResponse> ReverseGeocodeAsync(double latitude, double longitude)
{
ReverseGeocodeRequest reverseGeocodeRequest = new ReverseGeocodeRequest();
// Set credentials using a Bing Maps key
reverseGeocodeRequest.Credentials = new GeocodeService.Credentials();
reverseGeocodeRequest.Credentials.ApplicationId = Application.Current.Resources["BingCredentials"] as string;
// Set the coordinates
reverseGeocodeRequest.Location = new GeocodeService.GeocodeLocation() { Latitude = latitude, Longitude = longitude };
// Make the reverse geocode request
GeocodeServiceClient geocodeService = new GeocodeServiceClient(GeocodeServiceClient.EndpointConfiguration.BasicHttpBinding_IGeocodeService);
GeocodeResponse geocodeResponse = await geocodeService.ReverseGeocodeAsync(reverseGeocodeRequest);
return geocodeResponse;
}
