将 EMF 生成的 java 类集成到 Android 项目中
我想知道是否可以将从 EMF(ecore)模型生成的一组类包含到 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): VFY: unable to find class referenced in signature (Lorg/mmi/events/Event;)
和这样的:

感谢您的帮助!
I would like to know if I can include a set of classes generated from an EMF (ecore) model into an Android project.
I am trying to do this, it compiles fine, but in run-time I get errors like the following ones:
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): VFY: unable to find class referenced in signature (Lorg/mmi/events/Event;)
and like this:

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。您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%253Dclose
我还需要包含在javax.xml.* 包。我删除了相应的注释,添加了 javax.xml jar 文件,现在一切都可以在 Android 中编译。
希望它能对您将来有所帮助。
干杯!
At the end I solved this problem using a modified version of the classes compounding the EMF core packages. You can find these classes here:
forum thread:
http://dev.eclipse.org/mhonarc/lists/emf-dev/msg01001.html
project homepage and repository:
http://code.google.com/p/smatrt/source/browse/#svn%2Ftrunk%2Ftmp%2Forg%253Fstate%253Dclosed
I needed also the XML classes included in the javax.xml.* package. I removed the corresponding comments, added the javax.xml jar file and now everything compiles in Android.
Hope it can be helpful for you in the future.
Cheers!
在 最近对相关 Eclipse bug 的评论中,Paul Allen 写道下列:
这似乎更可取,因为它不涉及修补核心 EMF 类。不过我自己还没有尝试过。
In a recent comment on the related Eclipse bug, Paul Allen wrote the following:
That seems preferrable, as it doesn't involve patching core EMF classes. I haven't tried it myself yet, though.
