Can I keep all the contents in my jar file in just one sentence when I run proguard?

Question

When I use proguard in android studio, I notice that there are -keep class mypakageName.**{*;} to keep the class in my package and -keep interface mypackageName.**{*;} to keep the interface in my package etc... but I find it is fussy, can't I keep all the files in my package in just one sentence? Or is there a method can do that?

Answer 1

使用-keep class将保留任何Java类型，包括类，接口，枚举。
