java.lang.NoClassDefFoundError&；java.lang.ClassNotFoundException-Android

我的第一个问题，所以我希望我做得对

我已经将平板电脑布局添加到我的Android项目中，现在我有一些关于各种设备的崩溃报告。对我来说，它100%工作正常，但是，使用平板电脑的测试人员在运行时会强制关闭

该应用程序是一个简单的仪表板，允许用户将主题应用到第三方启动器，就像Stark和Flatro图标包一样

以下是错误：

这里有一个转折点，主题仍然适用于Apex Launcher…任何帮助都将提前感谢

我记不起确切的答案，但这可能与库的导出有关。转到项目、属性、生成路径、顺序和导出。正确的顺序是src、gen、android x.x.x、android私有库、私有库。尝试检查/取消选中它们

我回家后会更新答案

编辑： 我的另一个答案可以在这里找到：

该应用程序是否仅在您在模拟器上时才对您有效，而不在物理设备上有效？它在我的两个物理设备上都有效。星系连接和星系S2。大多数报告来自Nexus 4和平板电脑…一些代码可能会有所帮助。好的，我还应该添加什么？您是使用已发布的APK（更好）进行自己的测试还是运行调试版本？我的第一个嫌疑犯是Proguard。任何激进的优化/混淆？我之前确实读过。感谢您的帮助，我现在正在测试Ander Webbs的解决方案，当我了解更多信息时，我会报告。我根据Ander的建议从构建pat中删除了support.jar，然后重新安装了android支持库
