我在写一个连接到web服务的应用程序，如果它无法获得连接，我不希望它等待太久。因此，我设置了httpparams的connectionTimeout。但它似乎没有任何影响。如何在Android上设置Http连接超时

这里是我的代码

public void doPost(ArrayList list) {

HttpPost post = new HttpPost(URL);

HttpParams httpParameters = 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 = 3000;

HttpConnectionParams.setConnectionTimeout(httpParameters,

timeoutConnection);

// Set the default socket timeout (SO_TIMEOUT)

// in milliseconds which is the timeout for waiting for data.

int timeoutSocket = 5000;

HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters);

httpClient.setParams(httpParameters);

try {

post.setEntity(new UrlEncodedFormEntity(list));

HttpResponse response = httpClient.execute(post);

Log.i("response ", response.toString());

Log.i("response code", ""

+ response.getStatusLine().getStatusCode());

if (response != null) {

HttpEntity entity = response.getEntity();

if (entity != null) {

InputStream instream = entity.getContent();

result = convertStreamToString(instream);

Log.i("Result ", result);

// Closing the input stream will trigger connection release

instream.close();

}

} else {

Log.i("SERVER ERROR ", "Server Not responding");

}

} catch (UnsupportedEncodingException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (ClientProtocolException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

我现在加入异常

但我的日志美食dosent5秒内显示任何错误。它会给我2 3薄荷错误。

这里是错误
