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

1. 在我确信WRITE_EXTERNAL_STORAG​​E加入。
2. 我启用了内存和磁盘缓存

我终于不用改变一行服务器code解决我的问题。我所做的是与替换默认的 URLConnectionImageDownloader HttpClientImageDownloader

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

code样品：<​​/ P>

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();
