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.

Image URL: http://i10.topit.me/l046/10046137034b1c0db0.jpg

Please help.

Just a wild guess, but those images might need a proxy to be accessed and I remember there were issues with proxies in API level 8. – Forsterite

Not likely. All the images are hosted on the same server. Most of them can be downloaded on my testing Android device without a problem – Pincenez

I get a 404 visiting that page (which would cause file not found), although the 404 page is just an image located at img.topit.me/404.jpg that says (love)it.me. – Methylnaphthalene

And now I don't. Use a better image server. – Methylnaphthalene

Follow up:

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();

Am I unlucky !!! getting --- SkImageDecoder::Factory returned null, using HttpClientImageDownloader – Adallard

Thanks a lot!! It's helps me. Just one thing in code, need context in last line: .imageDownloader(new HttpClientImageDownloader(msContext, new DefaultHttpClient(manager, params))) – Tatty

@DiWu Sorry mate for query im facing same problem. But im using latest version of UIML. In which class you done this changes ? URLConnectionImageDownloader with HttpClientImageDownloader Name of the package and class ? – Rajab

Not able to implement this. What is HttpClientImageDownloader class.Pls help – Lallans

What is HttpClientImageDownloader class? – Iden

I cannot implement this HttpClientImageDownloader, how to make it works? – Chickamauga

Nostra removed the class from the library. See: github.com/nostra13/Android-Universal-Image-Loader/commit/… – Mealy

Answer 2

Look for implementation of libcore.net.http.HttpURLConnectionImpl.getInputStream()

 @Override
    public InputStream getInputStream() throws IOException {
        if (!doInput) {
            throw new ProtocolException("This protocol does not support input");
        }

        retrieveResponse();

        /*
         * if the requested file does not exist, throw an exception formerly the
         * Error page from the server was returned if the requested file was
         * text/html this has changed to return FileNotFoundException for all
         * file types
         */
        if (responseCode >= HTTP_BAD_REQUEST) {
            throw new FileNotFoundException(url.toString());
        }

        if (responseBodyIn == null) {
            throw new IOException("No response body exists; responseCode=" + responseCode);
        }

        return responseBodyIn;
    }

According to this it can throw FileNotFoundException even if server error occurs or unauthorized.

I have not found value of HTTP_BAD_REQUEST but it's always was 400. Source code link http://www.java2s.com/Open-Source/Android/android-core/platform-libcore/org/apache/harmony/luni/internal/net/www/protocol/http/HttpURLConnectionImpl.java.htm

And if you go to the address you will find there is such file yourself: i10.topit.me/l046/10046137034b1c0db0.jpg – Forsterite

Yes, I've just did it. Seems that something strange happens. But stack trace definitely says that file was not found – Bankruptcy

Sometimes server really responds 404 (actually it constantly respond 404 after several successful responds). So this is not a UIL's problem. – Coprophagous

is there any solution to it – Adallard

Answer 3

The only thing you can do is to disable logging at all by L.disableLogging(). Or change the sources according to your needs. Source: nostra13's answer for this problem

Answer 4

This configuration tuning is custom. You can tune every option, you may tune some of them, or you can create default configuration by ImageLoaderConfiguration.createDefault(this); method.

 public static void initImageLoader(Context context) {

    ImageLoaderConfiguration.Builder config = new ImageLoaderConfiguration.Builder(context);
    config.threadPriority(Thread.NORM_PRIORITY - 2);
    config.denyCacheImageMultipleSizesInMemory();
    config.diskCacheFileNameGenerator(new Md5FileNameGenerator());
    config.diskCacheSize(50 * 1024 * 1024); // 50 MiB
    config.tasksProcessingOrder(QueueProcessingType.LIFO);
    config.writeDebugLogs(); // Remove for release app

    // Initialize ImageLoader with configuration.
    ImageLoader.getInstance().init(config.build());
}

I hope this helps anyone.
