Location permission for Android above 6.0 with Xamarin.Forms.Maps

Question

I\'m trying to implement a Xamarin.Forms application using Xamarin.Forms.Maps, however I always fall into the exception:

Java.Lang.SecurityException: my location req

Answer 1

add this inside android MainActiviy OnCreate()

Plugin.CurrentActivity.CrossCurrentActivity.Current.Activity = this;

add this to android mainactivity:

public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Android.Content.PM.Permission[] grantResults)
{
    Plugin.Permissions.PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode, permissions, grantResults);
    base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}

then this code will function, prompting user for location permission.

                var locator = CrossGeolocator.Current;
                locator.DesiredAccuracy = 1000;
                var position = await locator.GetPositionAsync(timeoutMilliseconds: 10000);
