我收到此错误：

Unexpected error while performing partial evaluation:
Class       = [org/apache/log4j/chainsaw/Main]
Method      = [<init>()V]
Exception   = [java.lang.IllegalArgumentException] (Can't find any super classes of [org/apache/log4j/chainsaw/LoadXMLAction] (not even immediate super class [javax/swing/AbstractAction]))
Error: Can't find any super classes of [org/apache/log4j/chainsaw/LoadXMLAction] (not even immediate super class [javax/swing/AbstractAction])

我的proguard配置的一部分：

那里有log4j的库,那么可能是什么问题？

更新

正如我发现的那样,在优化过程中会出现问题.
收缩和混淆正在起作用.

解决方法:

对于需要在Android上使用Log4J的快速解决方案的用户,Krivers的更新实际上是一个提示：在ProGuard配置中设置-dontoptimize将关闭优化,从而避免出现错误(尽管这仅应视为解决方法).

实际上,Android Tools Project网站也有suggested to turn off ProGuard optimization：

Dalvik performs many of its own optimizations, and some of the optimizations performed by ProGuard are incompatible with Dalvik, so to avoid hard-to-figure-out bugs (and because the net performance gain is usually small), the default configuration turns off optimization.
