Android Studio.无法正确包含外部库

Question

我正在尝试添加到classpath外部库(这一个).我这样做的方式:File -> Project Structure -> Dependencies tab -> Add file dependency.那是对的吗？Maven的库列表没有Xstream.如果我点击add module dependency列表是空的.

所有我需要的是3个jar文件添加到类路径- xstream1.4.7.jar,xmlpull-1.1.3.1.jar和xpp3_min-1.1.4c.所以我按照以前写的那样做了.事情是,在此之后,我可以包括这个库,一切似乎都好.但在运行项目后出现错误:

    Error:Execution failed for task ':gridview:dexDebug'.

此外,我已经在Intelij中使用常见的java测试了这个库,而不是android.这非常有效.所以我只是将工作代码从Intelij复制到Android Studio中,并且发生了错误.

这是发生此错误的代码(如果需要):

FileReader reader = new FileReader("boards.xml");  // load file
XStream xstream = new XStream();
xstream.processAnnotations(Boards.class);
xstream.processAnnotations(IdBoards.class);
Boards boards = (Boards) xstream.fromXML(reader); // parse xml into array list

所以问题是如何正确地将外部库添加到Android Studio？或者probaby还有其他问题吗？谢谢你的建议.

xml pull解析器是android框架的一部分,删除xmlpull-1.1.3.1.jar并尝试它可能工作.
