android - 从 Google Play 下载时出现 ClassNotFoundException

Question

我遇到了一个涉及 ClassNotFoundException 的问题。当我从 Eclipse 中“作为 Android 应用程序运行”时它工作正常，但是当我从 Google Play 下载它时(相同的源代码但“导出为已签名的应用程序”)它崩溃并出现以下堆栈跟踪:

java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.larphoid.aeboing/com.larphoid.aeboing.BoingBoing}: java.lang.ClassNotFoundException: com.larphoid.aeboing.BoingBoing in loader dalvik.system.PathClassLoader[/data/app/com.larphoid.aeboing-1.apk]

我以前从未遇到过这个问题，而且我还没有“阅读”Stacktraces 的经验，所以我对此感到非常困惑。如果有人有一些指示或解决方案，我将不胜感激。

谢谢。

从另一个问题中复制这个，因为我之前遇到过完全相同的问题，这就是我修复它的方法:

If you're running adt rev 22, you might not be exporting your libraries. I don't know why Google did this exactly, but in the newest revolution you have to check to make sure you're exporting your libraries yourself.

Right click your project, click Properties, and check Order & Export under Java Build Path. It should look like this if you want to export everything:

Afterwards, rebuild the application and export it again. It should be working now. To test, simply install the .apk to your phone manually before putting it on the store to make sure it works.
