使用Android Proguard之后，打开应用程序时出现此错误：java.lang.NoSuchMethodError

Question

这是发生了什么事，但我不知道出了什么问题。任何可以帮助我的人都会感激不尽。

java.lang.NoSuchMethodError: No static method c(Ljava/lang/String;Ljava/lang/String;)I in class Landroid/util/Log; or its super classes (declaration of 'android.util.Log' appears in /system/framework/framework.jar:classes2.dex)
