问题标签 [android-parser]

我已经制作了这个应用程序，我已经测试了一段时间。完成后，我将它放在 Market 商店中，一切都很好，但现在制作了一个新版本，没有更改清单，当我尝试安装它时，它在我的手机上出现错误：

解析包时出现问题。

我以前使用该应用程序没有问题，但为什么现在？

我一直在阅读本教程并遇到了它使用非常低的 api 的问题。我得到了 NetworkOnMainThreadException。我在stackoverflow上找到了这个答案，它说我必须使用 AsyncTask。

我曾尝试在一个空项目上使用 AsyncTask 并使用另一个运行良好的教程。

我的问题是我需要更改这个项目，以便我可以在更高的 api 上使用它。所以问题是 AndroidSaxFeedParser 是一个子类，AsyncTask 是一个超类，错误行在 AndroidSaxFeedParser 上，它扩展了 BaseFeedParser 和 BaseFeedParser 扩展了作为接口的 FeedParser（顺便说一句，我一直认为接口必须实现而不是扩展？）。

更准确地说，错误在这些行上（用 ---> 表示）： AndroidSaxFeedParser.java ：

消息列表.java：

BaseFeedParser.java：

那么我应该在哪里以及如何使用 AsyncTask。（我只使用 AndroidSaxParser，所以教程中的其他解析器可以忽略）。

AndroidSaxFeedParser.java

BaseFeedParser.java

FeedParser.java

FeedParserFactory.java

消息.java

消息列表.java

ParserType.java

RssHandler.java

我得到BufferedReader的对象是空白的，当我调试我的代码时，我发现实际上该HttpEntity对象也似乎是空的。

这是我的部分代码：

// 发出HTTP请求

如果我在 PC 浏览器上点击我的网址，它会给出 JSON 响应，并且还会在 [http://jsonlint.com/][1] 上

具体是什么问题，看不懂

解析时显示错误。我只想传递用户获得的整数值。但它在解析时显示错误。因此，此外，纠正如何接受用户的整数值以及如何以整数格式传递它的问题。编码：

edittext的xml部分

堆栈跟踪：

java.lang.reflect.Method.invoke(Method.java:507)

在我的 Android 应用程序中，我从 PHP url 获取 JSON 响应字符串。从我得到一些酒店名称的回复中apostrophe，我得到了&#039字符而不是apostrophe。如何在android中解析带有特殊字符的酒店？I can see the apostrophe in the browser but could not see in android logcat.

我试过了jresponse = URLEncoder.encode(jresponse,"UTF-8");，但我找不到apostrophe酒店名称。

这是响应中的酒店名称之一。

我正在尝试使用购买状态 API ( https://www.googleapis.com/androidpublisher/v1.1/applications/packageName/subscriptions/subscriptionId/purchases/token ) 获取订阅到期日期，但低于响应。我可以知道什么是实现我的目标的正确方法吗？

有人知道怎么做吗？

提前致谢。

我正在尝试将 JSON 解析数据转换为 android。

我无法理解我的错误是什么。

我也是java和android的初学者。

这段代码不难，你不会无聊。

我的错误和代码如下所示：

主要活动：

自定义适配器：

项目清单：

在我的 android 应用程序中，我面临一个非常奇怪的错误，无法进入它的根目录。我进行网络调用并解析 JSON 响应。但应用程序崩溃，我收到以下错误。

它随机发生并且无法重现错误。如果以前遇到过这种情况的人可以告诉我什么可能触发这次崩溃，那将非常方便。

JSON Parser 使用带有进度条的 asynctask。这样做的正确方法是什么？

我应用并调整了从 tuts 中读取的内容，但是从 downloadTask 返回数据时返回 null

这是我的 downloadTask 任务：

这基本上是 populateCampaigns 方法：

最后，这是解析器方法：

嗨朋友们，我知道关于这个话题有很多问题，但我无法从他们那里得到任何结果。我正在使用我的 ClassIsInternalParser 解析 xml 数据扩展默认处理程序。我在内部类 PostAsync extends AsyncTask 的活动中使用此类

但原因是我无法将我在 PostAsync 类中收集的数据返回给主要活动。它只设置 null

这是我的代码
