我刚刚创建了模板Libgdx项目(Core,Android,Windows).核心是常规的Java项目库. Core中对XStream.jar库有依赖性. Core包含通过Xml输入和输出的文件. Android项目具有对Java核心项目的依赖.
现在,XStraem适用于Windows,但不适用于Android.对于Android,我得到了：

如果我将库添加到Android项目的构建路径中,则会得到：
[2014-01-22 13:23:06 - Dex Loader] Unable to execute dex: Multiple dex files define Lorg/xmlpull/v1/XmlPullParser;
[2014-01-22 13:23:06 - drag-android] Conversion to Dalvik format Failed: Unable to execute dex: Multiple dex files define Lorg/xmlpull/v1/XmlPullParser;
当我在Core中检查库时,同样的东西->订购和出口
来自LibGDX的有关创建核心项目的文档：
Main project setup Create a new Java project in Eclipse: File -> New
-> Project -> Java Project. Give it a name and click Finish.Go to the project folder on the file system and create a sub-folder named libs.
Download the nightly zip and place gdx.jar and gdx-sources.jar in the
libs folder.In Eclipse, right click the project -> Refresh. Right
click again -> Properties -> Java Build Path -> Libraries -> Add JARs,
select gdx.jar and click OK.Under the gdx.jar file, double click
“Source attachment”, click Workspace, select the gdx-sources.jar and
click OK.Click the Order and Export tab, check the gdx.jar and click
OK.Note: Step 5 makes gdx.jar a transitive dependency. That means that
projects that depend on the main project will also have gdx.jar on
their classpath. However, this doesn’t work for Android projects.
这是否意味着Java核心项目中包含的任何依赖项在Android上均不起作用？
有没有办法让XStream传输库正常工作？
解决方法:
如果Android上支持该库,则它将起作用.
将其放在Core项目的“ libs”文件夹中.将其添加到其订单和导出标签.
将其添加到Android项目的“库”标签中. (“添加罐子”,而不是“添加外部罐子”),然后在“订单和以及导出选项卡.
That means that projects that depend on the main project will also have gdx.jar on their classpath. However, this doesn’t work for Android projects.
这只是意味着Core项目的类路径中的库不会自动添加到Android项目中(据我所知,前一段时间确实如此).
