Sample code:

 private async Task<bool> CheckExternalStoragePermission()
        {
            var externalStorageStatus = false;
            try
            {
                var status = await CrossPermissions.Current.CheckPermissionStatusAsync(Permission.Storage);
                if (status != PermissionStatus.Granted)
                {
                    if (await CrossPermissions.Current.ShouldShowRequestPermissionRationaleAsync(Permission.Storage))
                    {
                        await Mvx.Resolve<IUserDialogs>().AlertAsync(Catalog.GetString("We need permission to store the downloaded files"),
                            Catalog.GetString("Permission to access storage"));
                    }

                    var results = await CrossPermissions.Current.RequestPermissionsAsync(new[] { Permission.Storage });
                    status = results[Permission.Storage];
                }

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

                    await Mvx.Resolve<IUserDialogs>().AlertAsync(Catalog.GetString("Cannot continue sharing."), Catalog.GetString("Storage Permission Denied"));
                }
            }
            catch (Exception ex)
            {
                Debug.WriteLine("Exception while requesting Storage permission: "+ex);
                externalStorageStatus = false;
            }

            return externalStorageStatus;
        }
