一个android 中的异常问题？

try {

            DefaultHttpClient httpclient = new DefaultHttpClient();             
            HttpDelete delete=new HttpDelete(url);
            put.setHeader("Content-Type","application/vnd.org.snia.cdmi.container");
            response = httpclient.execute(delete);
            content = response.getEntity().getContent();
            String result=response.getStatusLine().toString()+"\n"+response.getHeaders(url);
            return result;
          }catch (Exception e) {
            Log.e("[DELETE REQUEST]", "Network exception");
          }
          return "";
        }
