Android - docx4j 构建问题

Question

我正在开发一个安卓应用程序。我需要在其中显示我的应用程序中的 docx、xlsx 文件。我在互联网上搜索过，发现 docx4j 会将 docx、xlsx 文件转换为 html（或）pdf。所以我打算在 webview 中显示 docx4j 的 html 返回。

所以我已经从github 下载了源代码并尝试运行示例。我也对链接​​中给出的 eclipse.ini 文件进行了更改。

但是，我无法执行应用程序。当我运行应用程序时，出现以下异常。

[2014-11-24 17:19:34 - AndroidDocxToHtml-master] Conversion to Dalvik format failed with error 1

详细日志：

[2014-11-24 17:19:34 - AndroidDocxToHtml-master] Dx warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.xml.serializer.SecuritySupport12$8) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

我只在应用程序中添加了一次库。

可能是什么问题。谁能帮我解决这个问题？

Answer 1

我终于找到了解决方案。我确实添加了他们在github 中给出的所有罐子。所以我得到了上述异常。

现在我从工作区中删除了 "serializer-2.7.1.jar"，然后构建了应用程序。我可以将 docx 转换为 html 而不会出现构建问题。现在工作正常。
