android - 将 EMF 生成的 java 类集成到 Android 项目中

Question

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，但在运行时出现如下错误:

---

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:

感谢您的帮助!!!

Answer 1

最后，我使用混合了 EMF 核心包的类的修改版本解决了这个问题。您可以在这里找到这些类:

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%253Dclosed

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，现在所有内容都可以在 Android 中编译。

希望以后能对你有所帮助。干杯!
