Volley库中的TimeOut错误

Question

即使将超时间隔设置为1分钟，我也会在凌空库上遇到一个奇怪的超时问题。它以前运行正常，但从最近几天它总是显示服务器超时错误。

请查看下面的代码段：

public class AppVolley {

    private static AppVolley instance;
    private static RequestQueue mRequestQueue = null;
    private static ImageLoader imageLoader = null;
    private static Context mContext = null;

    private AppVolley(Context context) {
        mContext = context;
        mRequestQueue = getRequestQueue();

        imageLoader = new ImageLoader(mRequestQueue, new ImageLoader.ImageCache() {
              private final LruCache<String, Bitmap> cache = new LruCache<String, Bitmap>(20);


              @Override
              public Bitmap getBitmap(String url) {
                  return cache.get(url);
              }

              @Override
              public void putBitmap(String url, Bitmap bitmap) {
                  cache.put(url, bitmap);
              }
        });
    }

    // Initialize Telkom volley
    /**
     * Initialize Telkom volley
     * @param context of Application
     * @return
     */
    public static AppVolley getInstance(Context context) {
        if(instance == null) {
            instance = new AppVolley(context);
        } else {
            throw new IllegalStateException("Developer forget to initialize request queue");
        }

        return instance;
    }

    // Return single request queue through out application
    /**
     * Return single request queue through out application
     * @return request queue of volley
     */
//  public static RequestQueue getRequestQueue() {
//      return mRequestQueue;
//  }

    public static RequestQueue getRequestQueue() {
        // lazy initialize the request queue, the queue instance will be
        // created when it is accessed for the first time
        if (mRequestQueue == null) {
            BasicHttpParams mHttpParams = new BasicHttpParams();
            // Set the timeout in milliseconds until a connection is
            // established.
            // The default value is zero, that means the timeout is not used.
            int timeoutConnection = 60*1000;
            HttpConnectionParams.setConnectionTimeout(mHttpParams,
                    timeoutConnection);
            // Set the default socket timeout (SO_TIMEOUT)
            // in milliseconds which is the timeout for waiting for data.
            int timeoutSocket = 60*1000;
            HttpConnectionParams.setSoTimeout(mHttpParams, timeoutSocket);

            SchemeRegistry schemeRegistry = new SchemeRegistry();
            schemeRegistry.register(new Scheme("http", PlainSocketFactory
                    .getSocketFactory(), 80));
            final SSLSocketFactory sslSocketFactory = SSLSocketFactory
                    .getSocketFactory();
            schemeRegistry.register(new Scheme("https", sslSocketFactory, 443));
            ClientConnectionManager cm = new ThreadSafeClientConnManager(
                    mHttpParams, schemeRegistry);
            DefaultHttpClient defaultHttpClient = new DefaultHttpClient(cm,
                    mHttpParams);

            mRequestQueue = Volley.newRequestQueue(mContext.getApplicationContext(), new HttpClientStack(defaultHttpClient));
        }

        return mRequestQueue;
    }

    // Return same image Loader through out application
    /**
     * Return Volley image loader instance
     * @return
     */
    public ImageLoader getImageLoader() {
        return imageLoader;
    }

}

我的调用函数是

private void initPreLoginSync(LoginResponse loginResponse)
    {
        RequestQueue mRequestQueue = AppVolley.getRequestQueue();
        JsonGenericVolleyRequest<GenericResponse> preSyncRequest = new JsonGenericVolleyRequest<GenericResponse>(
                AppSharedPreferences.getInstance(getActivity()).getSalfeldServerName() + AppConstants.WS_PRE_SYNC,
                myData,
                createSyncSuccessListener(),
                createSyncErrorListener(),
                GenericResponse.class);

        // Help to cancel web-service if required
        preSyncRequest.setTag(AppConstants.TAG_WS_PRESYNC);

        mRequestQueue.add(preSyncRequest);

    }
