How to get current location coordinates in the Map feature in Xamarin Application? - xamarin

Question

I am working on location coordinates marking feature in the App.
I am using following dll's and google map.
Xamarin.Forms.Maps
Xam.Plugin.Geolocator
Xam.Plugin.ExternalMaps
In my iphone simulator, If the Location is NONE.It pulls default location some where in Rome, Italy
Following is the code written to pull the Map ..
public async Task<Xamarin.Forms.Maps.Position> GetPosition()
{
IsBusy = true;
Xamarin.Forms.Maps.Position p;
try
{
if (!locator.IsGeolocationAvailable)
{
p = new Xamarin.Forms.Maps.Position();
}
if (!locator.IsGeolocationEnabled)
{
p = new Xamarin.Forms.Maps.Position();
}
var position = await locator.GetPositionAsync(timeoutMilliseconds: 10000);
p = new Xamarin.Forms.Maps.Position(position.Latitude,position.Longitude);
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
p = new Xamarin.Forms.Maps.Position();
}
IsBusy = false;
return p;
}
public async Task<object> GetCityName(double latitude, double longitude) {
HttpClient client;
client = new HttpClient();
client.MaxResponseContentBufferSize = 256000;
try
{
var response = await client.GetAsync("https://maps.googleapis.com/maps/api/geocode/json?latlng=" + latitude + "," + longitude);
if (response.IsSuccessStatusCode)
{
var result = await response.Content.ReadAsStringAsync();
var json = Newtonsoft.Json.Linq.JObject.Parse(result);
var reValue = "" + json["results"][0]["formatted_address"];
var strArr = reValue.Split(',');
if (strArr.Length > 2)
return strArr[strArr.Length - 2] + ", " +strArr[strArr.Length - 1];
else
return "";
}
else {
Debug.WriteLine(#"Failed.");
return "Failed";
}
}
catch (Exception ex)
{
Debug.WriteLine(#"ERROR {0}", ex.Message);
return ex.Message;
}
}

elaborate your problem please, and change your conditions as follows:
if (CrossGeolocator.Current.IsGeolocationAvailable)
{
if (CrossGeolocator.Current.IsGeolocationEnabled)
{
var position = await locator.GetPositionAsync(timeoutMilliseconds: 10000);
p = new Xamarin.Forms.Maps.Position(position.Latitude,position.Longitude);
}
else
{
throw new Exception("Geolocation is turned off");
// Geolocation is turned off for the device.
}
}
else
{
throw new Exception("Geolocation is turned off");
// Geolocation not available for device
}
Here now Handle the catches from GetPosition() Method to make sure you don't get the default location.
