标签： java android rss-reader

我已经下载了http://techiedreams.com/android-rss-reader-part-3-action-bar-with-animated-item/来创建一个自定义RSS阅读器一段时间，但最近它开始表现，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（其中顺便使用它们的5个星期完美地工作了很棒，我只是定制它以获得一些Java和Java的经验。 Android编程

然而，我一直陷入困境，我不知道如何解决这个问题。

这是我的活动LogCat的日志（这只是我从下载RSS链接器时得到的错误），它应该加载RSS提要并初始化ListActivity。

如果有必要，我可以在这里发布代码，但也可以在这里下载http://techiedreams.com/android-rss-reader-part-3-action-bar-with-animated-item/。

请注意，这一切都曾经在很长一段时间内发挥作用，直到昨天它才开始表现得像这样。

任何人都可以告诉我发生了什么事。

1 个答案:

答案 0 :(得分：2)

如果您仔细浏览日志，您会发现根本原因。

Caused by: java.lang.NoClassDefFoundError: org.jsoup.Jsoup

这会立即告诉您在android中找不到jsoup库。我在过去遇到类似的问题，其中android无法找到库。我已按照这些步骤纠正了这个问题。

  1. 在eclipse中打开“配置构建路径”
  2. 转到订单和导出标签
  3. 检查有问题的库。

    4. 这应该可以解决问题。
