当调用Permissions.RequestAsync<Permissions.LocationWhenInUse>()时，我没有得到任何结果，应用程序卡住了。无论用户接受还是拒绝请求。
我已经按照文档中的说明设置了MainActivity：

public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Permission[] grantResults)
{
    Xamarin.Essentials.Platform.OnRequestPermissionsResult(requestCode, permissions, grantResults);
    base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}

现在我尝试用下面的方法获取权限。但是RequestAsync调用被卡住了，我从来没有收到过一个答案。一旦权限被授予，应用程序被重启，一切都按预期运行。

public async Task CheckPermissions()
{
    var status = await Permissions.CheckStatusAsync<Permissions.LocationWhenInUse>();

    if (status != PermissionStatus.Granted)
    {
        status = await Permissions.RequestAsync<Permissions.LocationWhenInUse>();
    }
    

    if (status == PermissionStatus.Granted)
    {
        HasLocationPermissions = true;
    }
    else if (status != PermissionStatus.Unknown)
    {
        HasLocationPermissions = false;
    }
}
