Proguard保留所有Java接口

Question

How to keep all api interfaces and internal ones that are used like callbacks? I didn't find it there http://proguard.sourceforge.net/manual/examples.html

Answer 1

The URL already offer the answer.

A fast but sub-optimal alternative would be simply keeping all interfaces with "-keep interface *".

Update in 2016/3/25 To keep all methods in the Interface .

-keep interface * {
  <methods>;
}

Update in 2017/7/24 The class file of Java8 could store metadata for reflection on method parameters, include Interface . Proguard v5.3 could keep these metadata with following options :

-keepattributes MethodParameters
