Android 中的 ClassDefNotFound
我一直在努力尝试将我的实用程序罐子包含在我的项目中。 Android 文档明确指出，所有 import-via-filesystem 都不是必需的（http://developer.android.com/resources/faq/commontasks.html#addexternallibrary），但我已经尝试了所有建议；放入 libs 文件夹，清理项目，重新启动 eclipse。
有什么方法可以看到 eclipse 如何构建项目吗？我想看到它实际上试图包含我的罐子。
I've been jumping through hoops trying to include my utility jar in my project. Android documentation clearly states that all the import-via-filesystem should not be necessary (http://developer.android.com/resources/faq/commontasks.html#addexternallibrary) but I've tried all suggestions anyhow; putting in it a libs folder, clean the project, restarting eclipse.
Is there any way I can see how eclipse builds the project; I'd like to see that it actually tries to include my jar.

构建和清理还不够，您应该通过配置构建路径来添加 jar 文件。请按照下列步骤操作：
希望它有帮助，对我的英语感到抱歉
Build and Clean is not enough, you should add your jar file by configuring the Build Path. Follow these steps:
Hope it helps and sorry for my English
看来将 jar 添加到构建路径还不够。您必须将 jar 复制到项目的文件夹（例如 /libs）。
It seems that adding the jar to the build path isn't enough. You have to copy the jar to the project's folder (like to /libs).
我一直无法解决这个问题，但这似乎是由于Android交叉编译器无法正确处理生成的Jar造成的。作为解决方法，我开始将 java 文件从实用程序项目复制到 Android 项目中。
I was never able to solve the problem, but it seems to be caused by the Android cross compiler not being able to correctly process the generated Jar. As a work around I started copying the java files from the utility project into the Android project.
