  Hello @Enohara
  have you got any error ...put a break point and see what's happens.
  what is it the problem ..? convert the coordinates to address OR to have the coordinate ?

  @ChristopheBERNARD , I follow every step but when i try to run the application, nothing happens. Do i need to add some Nuget or any plugins?

  THIS IS MY MAIN ACTIVITY
  {
  [Activity(Label = "GetCurrentLocation", MainLauncher = true)]
  public class MainActivity : Activity, ILocationListener
  {
  static readonly string TAG = "X:" + typeof (MainActivity).Name;
  TextView addressText;
  Location currentLocation;
  LocationManager locationManager;

      string locationProvider;
      TextView locationText;
  
      public async void OnLocationChanged(Location location)
      {
          currentLocation = location;
          if (currentLocation == null)
          {
              locationText.Text = "LOPLOPLOPLOPOLPOLPOL";
          }
          else
          {
              locationText.Text = string.Format("{0:f6},{1:f6}", currentLocation.Latitude, currentLocation.Longitude);
              Address address = await ReverseGeocodeCurrentLocation();
              DisplayAddress(address);
          }
      }
  
      public void OnProviderDisabled(string provider)
      {
      }
  
      public void OnProviderEnabled(string provider)
      {
      }
  
      public void OnStatusChanged(string provider, [GeneratedEnum] Availability status, Bundle extras)
      {
      }
  
  
  
  
      protected override void OnCreate(Bundle savedInstanceState)
      {
          base.OnCreate(savedInstanceState);
  
          // Set our view from the "main" layout resource
          SetContentView(Resource.Layout.Main);
          addressText = FindViewById<TextView>(Resource.Id.txtAddress);
          locationText = FindViewById<TextView>(Resource.Id.txtCoordinate);
  
          FindViewById<Button>(Resource.Id.getAdd).Click += AddressButton_OnClick;
  
          InitializeLocationManager();
      }
  
      async void AddressButton_OnClick(object sender, EventArgs e)
      {
          if (currentLocation == null)
          {
              addressText.Text = "Can't determine the current address. Try again in a few minutes";
              return;
          }
          Address address = await ReverseGeocodeCurrentLocation();
          DisplayAddress(address);
      }
  
      async Task<Address> ReverseGeocodeCurrentLocation()
      {
          Geocoder geo = new Geocoder(this);
          IList<Address> addressList =
              await geo.GetFromLocationAsync(currentLocation.Latitude, currentLocation.Longitude, 10);
  
          Address address = addressList.FirstOrDefault();
          return address;
      }
  
      private void DisplayAddress(Address address)
      {
          if (address != null)
          {
              StringBuilder deviceAddress = new StringBuilder();
              for (int i = 0; i < address.MaxAddressLineIndex; i++)
              {
                  deviceAddress.AppendLine(address.GetAddressLine(i));
              }
              addressText.Text = deviceAddress.ToString();
          }
          else
          {
              addressText.Text = "LOPLOPLOP";
          }
      }
      private void InitializeLocationManager()
      {
          locationManager = (LocationManager)GetSystemService(LocationService);
          Criteria criteria = new Criteria
          {
              Accuracy = Accuracy.Fine
          };
          IList<string> acceptableProviders = locationManager.GetProviders(criteria, true);
  
          if (acceptableProviders.Any())
          {
              locationProvider = acceptableProviders.First();
          }
          else
          {
              locationProvider = string.Empty;
          }
      }
      protected override void OnResume()
      {
          base.OnResume();
          locationManager.RequestLocationUpdates(locationProvider, 0, 0, this);
      }
      protected override void OnPause()
      {
          base.OnPause();
          locationManager.RemoveUpdates(this);
      }
  }
  

  But just as I said, i follow every steps so it's just the same.

  Thanks in advance

  @Enohara have you set the permission in the manifest ?
  android.permission.ACCESS_FINE_LOCATION
  android.permission.ACCESS_COARSE_LOCATION

  code seems to be nice

  @Enohara
  i suppose you have a result as : current location is null and
  addressText.Text = "Can't determine the current address. Try again in a few minutes"; ???

  move with the device and i suppose the gps is actif ?
