How to handle HTTP timeout?
提问by Louis Evans
In my application, I am downloading JSON data from a ReST web service. Most of the time, this works fine, however sometimes the connection will time out.
在我的应用程序中，我从 ReST Web 服务下载 JSON 数据。大多数情况下，这工作正常，但有时连接会超时。
This is the code I use to set the timeout...
这是我用来设置超时的代码...
HttpConnectionParams.setConnectionTimeout( httpParameters, 20000 );
HttpConnectionParams.setSoTimeout( httpParameters, 42000 );
If the connection times out, the application crashes and closes, how do I handle a time out?
如果连接超时，应用程序崩溃并关闭，我该如何处理超时？

The HttpClient class throws a ConnectTimeoutException Exception, so you should listen for it:
HttpClient 类抛出 ConnectTimeoutException 异常，因此您应该监听它：
try {
HttpResponse response = client.execute(post);
// do something with response
} catch (ConnectTimeoutException e) {
Log.e(TAG, "Timeout", e);
} catch (SocketTimeoutException e) {
Log.e(TAG, " Socket timeout", e);
}

Increase your time of waiting for response like :
增加您等待响应的时间，例如：
HttpConnectionParams.setConnectionTimeout( httpParameters, 60000 ); //1 minute
HttpConnectionParams.setSoTimeout( httpParameters, 90000 ); // 1.5 minute
