我已经下载了 http://techiedreams.com/android-rss-reader-part-3-action-bar-with-animated-item/尝试创建一个自定义 RSS 阅读器一段时间，但最近它开始出现问题，起初我认为这是我自己的错，但后来我重新下载了前三个版本(顺便说一下，在我使用它们的 5 周内，它们运行良好) 它很棒，我只是对其进行了一些定制，以获得一些 Java 和 Android 编程经验

但是，我一直陷入困境，不知道该怎么做才能解决这个问题。

这是我的 Activity LogCat 日志(这只是我下载 RSS 阅读器时出现的错误，我将其链接了一点)它应该加载 RSS 提要并初始化 ListActivity。

如果需要，我可以在这里发布代码，但它也可以下载 http://techiedreams.com/android-rss-reader-part-3-action-bar-with-animated-item/在这里。

请注意，这一切过去很长一段时间都有效，直到昨天才开始出现这种情况。

谁能告诉我这是怎么回事。 .

最佳答案

如果仔细浏览日志，您会发现根本原因。

引起:java.lang.NoClassDefFoundError: org.jsoup.Jsoup

这会立即告诉您 jsoup 库在 android 中找不到。我过去遇到过类似的问题，android 无法找到这些库。我已按照这些步骤纠正问题。

  1. 在 eclipse 中打开“配置构建路径”
  2. 转到订购和导出标签
  3. 检查有问题的图书馆。

这应该可以解决问题。
