连接超时

Question

现在我正在使用HTTPRequest，一切都很好。但我想处理以下情况

Device is connected to wifi but wifi is not connected to internet

我使用的是对点时间，但老实说，它需要自己的时间来超时，这是40秒，不少于这一点。请求代码如下：

  public String[] doHttpGetWithCode_1(String url, String headerParam) throws Exception {


         weburl         = new URL(url);
         uri            = new URI(weburl.getProtocol(), weburl.getUserInfo(), weburl.getHost(), weburl.getPort(), weburl.getPath(), weburl.getQuery(), weburl.getRef());
         result         = new String[2];
         httpParameters = new BasicHttpParams();
            // Set the timeout in milliseconds until a connection is established.
         timeoutConnection = 3000;
         HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
            // Set the default socket timeout (SO_TIMEOUT) 
            // in milliseconds which is the timeout for waiting for data.
        timeoutSocket   = 3000;
        HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
        httpURL=(HttpURLConnection) weburl.openConnection();
        httpURL.setDoOutput(true);
        httpURL.setDoInput(true);
        httpURL.setRequestMethod("GET");
        client          =new  DefaultHttpClient(httpParameters);  
        httpget = new HttpGet(url);
        httpget.addHeader("Content-Type",   "application/json");
        httpget.addHeader("Authorization", "Basic " + Base64.encodeToString(("greggs:sausage123").getBytes(),Base64.NO_WRAP));
        httpget.addHeader("X-Auth-Signature",   headerParam);
        httpget.setParams(httpParameters);

        try{
            response    = client.execute(httpget);
            entity      = response.getEntity();
            is          = entity.getContent();
//          BufferedReader br = new BufferedReader(new InputStreamReader(in );
            reader      = new BufferedReader(new InputStreamReader(is, HTTP.UTF_8));
            sb          = new StringBuilder();
            line        = null;

                try {
                    while ((line = reader.readLine()) != null) {
                        sb.append(line + "\n");
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    try {
                        is.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
        }
        catch(ClientProtocolException CPE)
        {
            CPE.printStackTrace();
        }


            result[0] = response.getStatusLine().getStatusCode()+"";
            result[1] = sb.toString();
            return result;
        }

在运行突出显示的场景后，我得到了以下响应：

现在，我需要做的是添加计时器，以特定的时间间隔运行，需要一点帮助，在此之前，谢谢您的注意。
