如何解决这个问题

How to solve this problem

推荐答案

这是发生，因为有时你的服务器时间过长回应。其实这也可能发生由于速度较慢的网络，这样你就不能完全控制权。如果使用<一个href="http://developer.android.com/reference/org/apache/http/client/package-summary.html">HttpClient,你可以增加超时时间：

This is happening because some times your server is taking too long to respond. Actually this could also happening due to a slow network, so you don't have full control over it. If you were using HttpClient, you could increase the timeout period:

HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters, CONNECTION_TIMEOUT);
HttpConnectionParams.setSoTimeout(httpParameters, WAIT_RESPONSE_TIMEOUT);
HttpConnectionParams.setTcpNoDelay(httpParameters, true);

client = new DefaultHttpClient(httpParameters);

CONNECTION_TIMEOUT 是等待连接建立的时间。 WAIT_RESPONSE_TIMEOUT 是等待要接收数据的时间 - 在你的情况下，这是你需要增加

CONNECTION_TIMEOUT is the time to wait for a connection to establish. WAIT_RESPONSE_TIMEOUT is the time to wait for data to be received - in your case this is what you need to increase.

底线：

• 在停止使用URL和现在开始使用的HttpClient。
• 您所描述的情况是很常见的一种在生产中的应用，你需要照顾它。增加超时不会总是帮助，因为你的应用程序会出现暂停时，有一个速度较慢的网络。你可以添加一个重试机制或通知的请求失败的用户，让他再试一次。
