android http连接超时处理

android http连接超时处理，很重要，服务器出故障时，客户端要安全退出，哪怕给用户一个友好的提示，再退出，也总比crash掉更舒服。

/** * 检查服务器连接状态 * @param strurl * @return */public static boolean checkUrlStatus(String strurl){URL url = null;HttpURLConnection conn = null;  try {              url = new URL(strurl);              try {                  //InputStream in = url.openStream();              conn = (HttpURLConnection)url.openConnection();            conn.setDoInput(true);            conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");            conn.setRequestMethod("GET");            conn.setConnectTimeout(Constant.REQUEST_TIMEOUT);            conn.setReadTimeout(Constant.REQUEST_TIMEOUT);            conn.connect();                //in.close();            } catch (SocketTimeoutException e){                        return false;            } catch (IOException e) {                 return false;              }          } catch (MalformedURLException e) {              e.printStackTrace();          }    conn.disconnect();  return true;}
