FFImageLoading.Exceptions.DownloadAggregateException: One or more errors occurred. (Headers timeout)

[PNDTCS]

I am working in xamarin android project and loading image using this library with authentication header. I have send headers to this library in my MainActivity and loading image in another activity.

This works fine in xamarin iOS but in Xamarin Android getting header timeout error.

FFImageLoading nuget version : Xamarin.FFImageLoading.2.4.11.982

Please provide solution to fix this issue

I am having the same output message only on Android.

In my XAML, I have the following: <ffcache:CachedImage x:Name="HackneyLogo" HorizontalOptions="CenterAndExpand" VerticalOptions="FillAndExpand" WidthRequest="{StaticResource LogoWidthSize}" Aspect="AspectFit" RetryCount="3" RetryDelay="20" CacheType="All" CacheDuration="500" Scale="0.95" DownsampleToViewSize="True"/>

And in my code-behind I am simply declaring the Source: HackneyLogo.Source = new UriImageSource { Uri = new Uri(DataHelpers.GetLogo(1)) };

DataHelpers.GetLogo(int i) { } simply returns the string value of the URL from which the image is loaded.

As stated previously, this works just fine on iOS - I have no issue loading the image, but on Android my images do not get loaded.

[mos379]

any update on this? receiving this now too, but the images sometimes load. Not sure how to pinpoint, as I'm using this on a listview with quite a few items...

[max-kuzmin]

Same error

[jocontacter]

the same upd: Fixed via removing "UseLegacyRenderer" flag from Forms.SetFlags()

[pboisso]

@jocontacter, I'm curious, the "UseLegacyRenderer" flag does not seem to be documented, how did you use it exactely? Any other side effects on other components?

Thanks for sharing a solution.

[Jose-Develaw]

Same here. Are there any news regarding this issue?

I checked and I havent set "UseLegacyRenderer", so I dont think it is a viable solution

Thanks in advance

[nabilakhlaque]

Having same issue, anyone?

[nabilakhlaque]

Here is a "solution" that works fine.

var handler = new HttpClientHandler();
            handler.ClientCertificateOptions = ClientCertificateOption.Manual;
            handler.ServerCertificateCustomValidationCallback =
                (httpRequestMessage, cert, cetChain, policyErrors) => true;

            var client = new HttpClient(handler);
            ImageService.Instance.Initialize(new Configuration
            {
                HttpClient = client
            });

[Soundman32]

Here is a "solution" that works fine.

Ignoring certificate validation errors is a workaround, but it's not really solving the problem, it's just bypassing security.

Yes that's why I wrote it in quotes... ;)

[rus-vladimir]

For me this was caused by a timeout while getting http headers, so I just increased the timeout:

ImageService.Instance.Initialize(new FFImageLoading.Config.Configuration
{
    HttpHeadersTimeout = 60
});
