Android Studio.无法正确包含外部库 [英] Android Studio. Can't include external library properly
问题描述
我正在尝试将外部库(此)添加到类路径中.我这样做的方式: File->项目结构->依赖项标签->添加文件依赖项.那是对的吗?Maven的库列表没有Xstream.如果我单击添加模块依赖项，则该列表为空.
I'm trying to add to classpath external library (this one). The way I do it: File -> Project Structure -> Dependencies tab -> Add file dependency. Is that correct? Maven's list of libraries doesn't have Xstream. And if I click add module dependency the list is empty.
我所需要做的就是将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 .所以我做到了，就像以前写的那样.问题是，在此之后，我可以包括该库，一切似乎都很好.但是运行项目后，会出现错误:
All I need is to add 3 jar files to classpath - xstream1.4.7.jar, xmlpull-1.1.3.1.jar and xpp3_min-1.1.4c. So I did it as wrote before. The thing is that after this I can include this library and everything seems Ok. But after running the project there is an error:
Error:Execution failed for task ':gridview:dexDebug'.

此外，我已经在Intelij中使用常见的Java(而不是android)测试了该库.而且效果很好.因此，我只是将工作代码从Intelij复制到Android Studio中，并且发生了该错误.
Moreover, I have tested this library in Intelij with common java, not android. And that worked perfectly. So I just copied working code into Android Studio from Intelij and that error occurs.
以下是发生此错误的代码(如果需要):
Here's the code where this error occurs (if needed):
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
所以问题是如何将外部库正确添加到Android Studio?还是可能存在其他问题?感谢您的建议.
So the question is How to add external libraries properly to Android Studio? Or probaby there's some other problem? Thanks for advices.
推荐答案
xml pull解析器是android框架的一部分，请删除xmlpull-1.1.3.1.jar并尝试使用.
xml pull parser is a part of android framework, remove xmlpull-1.1.3.1.jar and try It might work.
