我试图用我的android测试应用程序在线更新我的记录，但我没能做到。我不知道怎么了，我真的需要你的帮助。非常感谢您的帮助

更新：

            // getting updated data from EditTexts

                e.printStackTrace();
            }

            return null;
        }

我得到了一个NULLPOINTERCEPTION

 int success = json.getInt(TAG_SUCCESS);

响应是：org.apache.http.conn。EOFSENSORINPUTSTREAM@417dbcf8试试这个

通过在InputStream上调用toString（），可以获得对象的哈希代码。试试这个：

Log.d("response", EntityUtils.toString(httpEntity));

我认为您的回复将不包含有效的json格式！！！！！张贴你的response@Hardik我已经添加了json响应，请检查它，因为响应不是有效的json格式，所以出现了异常！分析字符0处输入的数据org.json.jsonexception结尾时出错of@Hardik那么我必须做些什么来解决这个问题呢？您好，我尝试了这个，我得到了一个错误：内容已经被使用了将它替换到'is=httpEntity.getContent（）；'内容只能使用一次。

Log.d("response", EntityUtils.toString(httpEntity));
