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;
		}
