问题
Consider this proguard statement :
-keep public class * extends android.support.design.widget.CoordinatorLayout$Behavior { *; }
In this statement what does the addition of { *; } mean?
Does it preserve all methods? All fields? Or just the entire class?
回答1:
It is used as a wildcard in ProGuard to indicate all members and methods in the class.
