当我从 Eclipse 中“作为 Android 应用程序运行”时，我的应用程序运行良好。在过去，我也成功地导出了应用程序的签名版本。
现在，应用程序的导出版本突然立即崩溃。关键信息似乎是
原因：aaaab：选择的 LogFactory 实现没有扩展 LogFactory。请检查您的配置。（由 java.lang.ClassCastException 引起：应用程序已指定应使用自定义 LogFactory 实现，但类 'org.apache.commons.logging.impl.LogFactoryImpl' 无法转换为 'aaaac'。请检查自定义实现。可以在@http ://commons.apache.org/logging/troubleshooting.html找到帮助。）。
这是 Proguard 的设置。我错过了什么吗？
-dontwarn org.apache.**
-dontwarn org.apache.commons.logging.**
-ignorewarnings
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
只有在运行时动态加载的实现类可以转换为加载它的 LogFactory 类时，才能使用自定义 LogFactory 实现。有几种方法会导致此转换失败。最明显的是源代码实际上可能没有扩展 LogFactory。源可能是兼容的，但如果编译源的 LogFactory 类不是二进制兼容的，那么转换也将失败。
还有另一种更不寻常的方式会导致这种转换失败：即使二进制文件兼容，在运行时加载的实现类也可能链接到 LogFactory 类的不同实例。有关详细信息，请参阅技术指南。
在使用自定义 LogFactory 实现的容器中可能会遇到这种情况。该实现通常与 JCL 一起在共享的高级类加载器中提供。当应用程序类加载器包含 LogFactory 时，将从更高级别的类加载器加载实现。实现类将链接到由更高级别的类加载器加载的 LogFactory 类。即使 LogFactory 实现是二进制兼容的，因为它们是由不同的类加载器加载的，所以两个 LogFactory 类实例不相等，因此强制转换必须失败。
他们继续说潜在的修复包括：
有多种方法可以解决此问题。哪种修复是正确的取决于具体情况。
如果您乐于为应用程序使用另一个类加载策略，请选择一个类加载策略，以确保从包含自定义实现的共享类加载器加载 LogFactory。
如果要绕过容器适配机制，则在容器启动时将相应的系统属性设置为默认值：
-Dorg.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.LogFactoryImpl
如果您想继续使用默认的容器机制，那么： • 使用最新版本查找并替换容器使用的 commons-logging 实现 • 将应用程序中的 commons-logging jar 替换为 commons-logging-adapters jar。这将确保应用程序类加载器在加载 LogFactory 时将委托给它的父级。
我认为“-Dorg.apache.commons......”命令会进入 proguard-project.txt 文件，但这会导致应用程序甚至无法构建。所以底线，我不明白 apache 想说什么，我希望你们中的一些有经验的人可以提供一些清晰/指导。
这是堆栈跟踪：
