Can not load cache when network is disconnected

See original GitHub issue

I use a URL as the image source. First, I load the image with good netwok. The image can be shown well. Then I disconnect the network and restart App, the ImageView show Error placeholder.

The first time I load the image, it should have been cached. But why it can’t be shown when the network is disconnect?

I use the FFImageLoading for Xamarin Forms package from Nuget, version is v2.1.8.

Xamarin Studio Community Version 6.1.1 (build 15) Xamarin.Android Version: 7.0.1.3 (Xamarin Studio Community)

Any help please… Thanks.

I test it with a simple project, only have a Page.

App.xaml.cs

using Xamarin.Forms;

namespace FFImageLoadingTest
{
    public partial class App : Application
    {
        public App()
        {
            InitializeComponent();

            MainPage = new FFImageLoadingTestPage();
        }

        protected override void OnStart()
        {
            // Handle when your app starts
        }

        protected override void OnSleep()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume()
        {
            // Handle when your app resumes
        }
    }
}

FFImageLoadingTestPage.xaml

<?xml version="1.0" encoding="utf-8"?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:FFImageLoadingTest" x:Class="FFImageLoadingTest.FFImageLoadingTestPage" xmlns:ffimageloading="clr-namespace:FFImageLoading.Forms;assembly=FFImageLoading.Forms"
    Title="Basic XAML Example">

    <ffimageloading:CachedImage HorizontalOptions="Center" VerticalOptions="Center"
            WidthRequest="300" HeightRequest="300"
            DownsampleToViewSize="true"
            Source = "http://a.hiphotos.baidu.com/zhidao/pic/item/f9dcd100baa1cd11aa2ca018bf12c8fcc3ce2d74.jpg">
        </ffimageloading:CachedImage>
</ContentPage>

FFImageLoadingTestPage.xaml.cs

using Xamarin.Forms;

namespace FFImageLoadingTest
{
    public partial class FFImageLoadingTestPage : ContentPage
    {
        public FFImageLoadingTestPage()
        {
            InitializeComponent();
        }
    }
}

I am a novice in Xamarin. If I use FFImageLoading with a wrong method?

Thanks
