FileNotFoundException with Universal Image Loader

Question

This question is about this popular Android library, Universal Image Loader for Android: https://github.com/nostra13/Android-Universal-Image-Loader

1. I made sure WRITE_EXTERNAL_STORAGE is added.
2. I enabled both memory and disk cache
3. I used UnlimitedDiscCache for disk cache
4. I'm building against Android 2.2 SDK. The exception is found when I'm testing the app on a Android 4.1.2 Nexus S device.
5. For most of my images, the loading is smooth and fine. However, for certain images, I always get the same exception. Below is an example.

Please help.

I finally solved my problem without changing one line of server code. What I did is replacing the default URLConnectionImageDownloader with HttpClientImageDownloader

Code sample:

        HttpParams params = new BasicHttpParams();
        // Turn off stale checking. Our connections break all the time anyway,
        // and it's not worth it to pay the penalty of checking every time.
        HttpConnectionParams.setStaleCheckingEnabled(params, false);
        // Default connection and socket timeout of 10 seconds. Tweak to taste.
        HttpConnectionParams.setConnectionTimeout(params, 10 * 1000);
        HttpConnectionParams.setSoTimeout(params, 10 * 1000);
        HttpConnectionParams.setSocketBufferSize(params, 8192);

        // Don't handle redirects -- return them to the caller. Our code
        // often wants to re-POST after a redirect, which we must do ourselves.
        HttpClientParams.setRedirecting(params, false);
        // Set the specified user agent and register standard protocols.
        HttpProtocolParams.setUserAgent(params, "some_randome_user_agent");
        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        schemeRegistry.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));

        ClientConnectionManager manager = new ThreadSafeClientConnManager(params, schemeRegistry);


        ImageLoaderConfiguration config =
                new ImageLoaderConfiguration
                        .Builder(MainActivity.sharedMainActivity.getApplicationContext())
                        .defaultDisplayImageOptions(defaultOptions)
                        .discCache(new UnlimitedDiscCache(cacheDir))
                        .threadPoolSize(1)
                        .memoryCache(new WeakMemoryCache())
                        .imageDownloader(new HttpClientImageDownloader(new DefaultHttpClient(manager, params)))
                        .build();
