My Location

To enable My Location, you can set the MyLocationEnabled property to true. Additionally, the IsMyLocationButtonVisible property controls the visibility of the My Location Button, which focuses the map on the current position.

In order to show My Location, the location permissions have to be granted. To enable location access, depending on the system, you have to perform the following steps:

iOS Setup

Based on your use case, you need to configure the info.plist file as follows:

<string>This app needs access to location to continue.</string>
<string>This app needs access to location to continue.</string>
<string>This app needs access to location to continue.</string>

Android Setup

Ask for the AccessFineLocation or AccessCoarseLocation permissions. The following code is an example of how to do this in your MainActivity.cs:

protected override void OnCreate(Bundle savedInstanceState)
    TabLayoutResource = Resource.Layout.Tabbar;
    ToolbarResource = Resource.Layout.Toolbar;

    Xamarin.Forms.Forms.Init(this, savedInstanceState);
    // Initialize RedCorners.Forms.GoogleMaps
    RedCorners.Forms.GoogleMapsSystem.Init(this, savedInstanceState);

    LoadApplication(new App());

    // Ask for Location Permissions
    if (
        (ContextCompat.CheckSelfPermission(this, Manifest.Permission.AccessFineLocation) != Permission.Granted) ||
        (ContextCompat.CheckSelfPermission(this, Manifest.Permission.AccessCoarseLocation) != Permission.Granted))
        ActivityCompat.RequestPermissions(this, new [] {
            Manifest.Permission.AccessCoarseLocation}, 1);

Configure your AndroidManifest.xml to use the required permissions:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Read Current Location

To access the coordinates of the current location, you can use the MapLocationSystem singleton. Once the location is shown on the map, its Latitude and Longitude properties contain the most up-to-date location values for the device.

Additionally, you can subscribe to the OnMapLocationChanged event to get notified of the location changes.

var locationSystem = RedCorners.Forms.MapLocationSystem.Instance;
Console.WriteLine($"{locationSystem.Latitude}, {locationSystem.Longitude}");
