Question

我想获取设备的GPS位置。我正在为Xamarin使用 GeolocatorPlugin 来获取设备的经度和纬度。我的设备上启用了GPS。我已经向我的Android清单添加了权限，但仍然收到错误：“发生地理位置错误：未经授权” 。如何解决此问题？

try
{
   var locator = CrossGeolocator.Current;
   locator.DesiredAccuracy = 50;

    var position = await locator.GetPositionAsync();
    entLocation.Text = position.Longitude.ToString() + "," + position.Latitude.ToString();
}
catch (Exception ex)
{
    //will catch any general exception and set message in a string
    string msg = ex.Message;
    await DisplayAlert("error", msg, "ok");
}

将以下代码放入Android项目中的MainActivity.cs中。

if(CheckSelfPermission(Manifest.Permission.AccessCoarseLocation) != (int)Permission.Granted)
{
    RequestPermissions(new string[] { Manifest.Permission.AccessCoarseLocation, Manifest.Permission.AccessFineLocation }, 0);
}

Plugin.Geolocator授权错误
