        try

            HttpClient httpclient = new DefaultHttpClient();
            HttpPost method = new HttpPost(url);
            
            HttpResponse response = httpclient.execute(method);
            /*HttpEntity entity = response.getEntity();*/
            if(response != null){
                return response.getStatusLine().toString();
            }
            else{
                return "No string.";
            }
            
         }
         catch(Exception e){
             return "Network problem";
         }
    }
    
    
}




因為我們只要測試是否連線正常   回傳 200 為正常
只要有產生 php 的檔案就可以了!!
