Java 在的字符1处分析输入的数据org.json.jsonexception结尾时出错

我是android开发新手，我根据本教程构建了一个android应用程序

我已经完成了教程中所述的所有操作，但当我运行emulator时，我收到以下消息：

分析数据org.json.jsonexception结尾处的输入时出错

代码如下：

正如在你的json文件中一样，标签是以url的形式列出的，即使我的应用程序也出现了这个异常，但在我的情况下，是JSONException从服务器以null形式出现…我想在你的情况下也可能是同样的问题…可能是你的php标签或php链接的响应不正确或即将出现nul…似乎

请注意，它不会以“]”结尾，一个字符串中包含的数据太多，一次只发送10个prdct，当用户到达列表视图的末尾时再发送10个prdct
我忘了说php包含希腊和英语字符……这会导致问题吗？例如：BufferedReader=new BufferedReader（new InputStreamReader，Web，“ISO-8859-1”），8）；只需删除这些内容并在BufferedReader=new BufferedReader（new InputStreamReader（is））中执行；als尝试使用jst包含英语的o/p请提供您的错误日志只需删除这些内容并在BufferedReader=new BufferedReader（new InputStreamReader（WEB））中执行即可；和als尝试使用jst包含英语的o/p，请提供您的错误登录我已经尝试了您的说明，但仍然是相同的错误…我不知道这是否对您有帮助，但正如我看到的数据库，它是用utf-8_general_ci创建的…请复制您的日志猫并粘贴到Hered上。您知道如何修复它吗？我将php测试到web浏览器，然后我不熟悉php…所以我对php没有概念…在我的例子中是服务器问题。。。
