我想知道是否可以将一组从 EMF（ecore）模型生成的类包含到 Android 项目中。

我正在尝试这样做，它编译得很好，但在运行时我收到如下错误：

06-07 11:37:04.261: INFO/dalvikvm(649): Failed resolving Lorg/mmi/events/Event; interface 318 'Lorg/eclipse/emf/ecore/EObject;'
06-07 11:37:04.261: WARN/dalvikvm(649): Link of class 'Lorg/mmi/events/Event;' failed
06-07 11:37:04.261: WARN/dalvikvm(649): VFY: unable to find class referenced in signature (Lorg/mmi/events/Event;)

像这样：

最后，我使用复合 EMF 核心包的类的修改版本解决了这个问题。你可以在这里找到这些课程：

论坛主题： http ://dev.eclipse.org/mhonarc/lists/emf-dev/msg01001.html 项目主页和存储库： http ://code.google.com/p/smatrt/source/browse/#svn% 2Ftrunk%2Ftmp%2Forg%253Fstate%253D已关闭

我还需要 javax.xml.* 包中包含的 XML 类。我删除了相应的注释，添加了 javax.xml jar 文件，现在一切都在 Android 中编译。

希望它对您将来有所帮助。干杯!

In a recent comment on the related Eclipse bug, Paul Allen wrote the following:

Just thought I'd post a note that things are working. If I jar up the un-modified classes from the org.eclipse.emf.common, org.eclipse.emf.ecore, and org.eclipse.emf.ecore.xmi plugins along with my model's generated classes, and import that into the libs folder of my Android project, things just work. The compiler's happy. The app runs on my Nexus 7. Life is good.

That seems preferrable, as it doesn't involve patching core EMF classes. I haven't tried it myself yet, though.
