使用自定义 JAR 运行 APK 时出现 NoClassDefFoundError答案

【问题标题】：NoClassDefFoundError when running APK with custom JAR使用自定义 JAR 运行 APK 时出现 NoClassDefFoundError

【问题描述】：

它编译得很好。加载到我的测试设备就好了。当我运行它时，它会崩溃并显示“抱歉，Bat 应用程序 Ear（进程 com.fleenlab.LWPA_EarOfBat）已意外停止。请重试。”在设备屏幕上和一堆“解析失败”和“类链接失败”，然后是 logcat 中的“FATAL EXCEPTION....NoClassDefFound”。

JAR 是我在 Eclipse 上编写的普通 Java。

是的，许多其他人都遇到过同样的问题。

我尝试了那个流行的解决方案 (http://android.foxykeep.com/dev/how-to-fix-the-classdefnotfounderror-with-adt-17)。我将我的 JAR 放在 libs 文件夹中。没运气。

我还尝试了变体解决方案：将 JAR 称为外部 JAR 并设置“订购和导出”复选框。仍然没有运气。

我什至反编译了 APK（使用 apktool）来查看类是否被正确打包。他们是。

我受阻了。有什么线索吗？

【问题讨论】：

是否在清单中定义？同时发布完整的输出。
您的意思是在清单中定义 Jar？我会试试的。这是 logcat 输出：
你想要整个输出？它相当大。 Here's the text file
清除所有项目并重试
这是我尝试的第一件事。每次我认为可能有帮助时，我都会清理它们。刚刚再次清理它们......将apk加载到设备中......不。仍然崩溃。

【解决方案1】：

这是一个依赖关系。 Grid 依赖于 TreeNode，它在 Swing 中，而不在 JAR 中。我的解决方案是摆脱 TreeNode。反正也不是很需要。现在工作正常。

我知道 logcat 说 NoClassDefFound 发生在 Grid，但问题实际上不是缺少 Grid 类定义，而是 Grid 所引用的类缺少定义。
