升级到 ADT 22 后，库不再添加到 APK [英] Libraries do not get added to APK anymore after upgrade to ADT 22

问题描述

我有一个相当大的 Android 应用项目，它引用了几个库项目.一切都很好，直到我将 eclipse ADT 插件升级到最新版本 (v22).我当然也升级了SDK.我在 Eclipse 中没有看到任何编译错误，但是当我在手机上运行该项目时，我收到了 NoClassDefFoundError.

I have a rather big Android App project that is referencing several library projects. Everything was fine until i upgraded the eclipse ADT plugin to the newest version (v22). I also upgraded the SDK of course. I do not see any compile errors in eclipse, but when i run the project on the phone i get a NoClassDefFoundError.

java.lang.NoClassDefFoundError: org.acra.ACRA
....

arca 库包含在引用的库项目之一(在 libs 文件夹中)中，我可以在包资源管理器的Android 私有库"中看到它，正如我所说，没有编译错误.该项目在没有升级 ADT 的其他人的计算机上运行良好.

The arca library is included in one of the referenced library project (in the libs folder) and i can see it in the "Android Private Libraries" in the package explorer, also as i said, no compile errors. The project runs fine on everyone else's computer that did not upgrade ADT.

我已经尝试了很多东西，包括但不限于:

I have already tried a whole bunch of stuff including but not limited to:

• 重新安装安卓 SDK
• 下载新的 ADT 包
• 删除我所有的代码并从 git 中重新获取
• 将有问题的库复制到应用项目
• 注释掉使用这个库的代码 - 我只是在下一个库中得到同样的错误

一切都没有成功，所以我在这里真的很绝望.

all without any success, so i'm getting really desperate here.

如果有人能给我一个如何解决这个问题的提示，我会很高兴.

I would be really happy if anyone could give me a hint on how to solve that problem.

Quoting Streets of Boston from his adt-dev post:

升级时，新的Android Private"的Order and Export"图书馆"并不总是被检查.android-support-v4.jar 现在在这个Android 私人图书馆"部分.

When upgrading, the 'Order and Export' of the new 'Android Private Libraries' is not always checked. And the android-support-v4.jar is now in this 'Android Private Libraries' section.

要解决此问题，请转到订购和导出"并选中Android 私有"图书馆".然后刷新/清理/重建.

To fix this, go to 'Order and Export' and check 'Android Private Libraries'. Then refresh/clean/rebuild.

为库项目完成此修复"后，您可能需要关闭并重新打开任何依赖项目，因为他们可能看不到这个修复"立即地.

After you done this 'fix' for a library project, you may need to just close and re-open any depending project, because they may not see this 'fix' immediately.

试一试，如果幸运的话，它会解决您的问题.

Give this a shot and with luck it will solve your problem.
