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

Back trace:

01-14 00:24:42.125: ERROR/ImageLoader(1671): http://i10.topit.me/l046/10046137034b1c0db0.jpg java.io.FileNotFoundException: http://i10.topit.me/l046/10046137034b1c0db0.jpg at libcore.net.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:177) at com.nostra13.universalimageloader.core.download.URLConnectionImageDownloader.getStreamFromNetwork(URLConnectionImageDownloader.java:40) at com.nostra13.universalimageloader.core.download.ImageDownloader.getStream(ImageDownloader.java:27) at com.nostra13.universalimageloader.core.LoadAndDisplayImageTask.saveImageOnDisc(LoadAndDisplayImageTask.java:296) at com.nostra13.universalimageloader.core.LoadAndDisplayImageTask.tryLoadBitmap(LoadAndDisplayImageTask.java:204) at com.nostra13.universalimageloader.core.LoadAndDisplayImageTask.run(LoadAndDisplayImageTask.java:128) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:442)

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. Commented Jan 13, 2013 at 17:06
  • 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 Commented Jan 13, 2013 at 17:08
  • 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. Commented Jan 13, 2013 at 17:15
  • And now I don't. Use a better image server. Commented Jan 13, 2013 at 17:17

Reset to default

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
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)))
@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 ?
03-09 18:12:59.535: E/ImageLoader(9878): java.io.FileNotFoundException: dakabo.dk/images/phocagallery/Levende_vaerksted/dsc09327.jpg%20 03-09 18:12:59.535: E/ImageLoader(9878): at libcore.net.http.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:194) 03-09 18:12:59.535: E/ImageLoader(9878): at com.nostra13.universalimageloader.core.download.BaseImageDownloader.getStreamFromNetwork(BaseImageDownloader.java:124)
Not able to implement this. What is HttpClientImageDownloader class.Pls help

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
Yes, I've just did it. Seems that something strange happens. But stack trace definitely says that file was not found
Sometimes server really responds 404 (actually it constantly respond 404 after several successful responds). So this is not a UIL's problem.
is there any solution to it

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

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.
