Android 4.0 org.apache.http.conn.ConnectTimeoutException:连接到...超时

Question

我在ICS上测试我的应用程序时遇到了一个奇怪的问题.

在Android 2.X上使用以下代码效果很好(有时会发生超时但很少次):

    HttpParams httpParameters = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(httpParameters, CONNECTION_TIMEOUT);
    HttpConnectionParams.setSoTimeout(httpParameters, SOCKET_TIMEOUT);

    final DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);

    // Create a new HttpClient and Post Header
    HttpPost httpPost = new HttpPost(url);

    HttpResponse response = null;
    try {
        if (keys != null) {
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
        }

        // Cookies
        // Create a local instance of cookie store
        if (checkCookieValues()) {
            BasicClientCookie cookieSession = new BasicClientCookie(mCookieName, mCookieValue);
            cookieSession.setDomain(mCookieDomain);
            httpClient.getCookieStore().clear();
            httpClient.getCookieStore().addCookie(cookieSession);
        }

        // Execute HTTP Post Request
        response = httpClient.execute(httpPost);

        httpClient.getConnectionManager().shutdown();

    } catch (UnknownHostException e) {
        Log.e(TAG, "Error when calling postData", e);
    } catch (SocketTimeoutException e) {
        Log.e(TAG, "Error when calling postData", e);
    } catch (ClientProtocolException e) {
        Log.e(TAG, "Error when calling postData", e);
    } catch (SocketException e) {
        Log.e(TAG, "Error when calling postData", e);
    } catch (IOException e) {
        Log.e(TAG, "Error when calling postData", e);
    }

    return response;

在ICS上,一旦收到超时异常,所有下一次调用都将返回超时异常.

有人遇到过这个问题吗？有没有办法避免这个问题？我检查过并没有找到类似的问题(尤其是ICS).

谢谢你的回复!

Apache http 堆栈在 ICS 中已被弃用和损坏。铬现在已成为标准。确保 v8 是您设备的默认 Java 脚本引擎。
