我将这些行添加到proguard.txt

-keep public class org.achartengine.*.* { *; }
-keep public class org.achartengine.** { *; }
我通过添加以下行解决了问题：

-keep public class org.achartengine.*.* { *; } 
-keep public class org.achartengine.** { *; }
你能分享你的代码+xml文件吗。看看你的日志，这个错误似乎不是由ProGuard造成的，尽管有一些痕迹。通过阅读你的问题，然后是你的答案，我真的很困惑。你基本上是说引起你的问题的两条线是一样的。。。。神奇地解决了它？什么？
