Question

如果要保留内部类，请使用-keep public class com.example.MyClass$MyInnerClass { *; }（或-keep public class com.example.MyClass$* { *; }保留任何多个内部类）。

问题：是否可以保留一个类的所有内部类，这些内部类通过扩展或实现来匹配签名？

interface MyInterface { fun foo() }

class Foo : MyInterface {
  override fun foo() {}
  class Inner    // <- keep these with one rule for all `MyInterface` implementations
  class Another  // <- keep these with one rule for all `MyInterface` implementations
}

class Bar : MyInterface {
  override fun foo() {}
  class Third    // <- keep these with one rule for all `MyInterface` implementations
  class Fourth   // <- keep these with one rule for all `MyInterface` implementations
}

类似-keep public class (com.example.** implements io.foo.bar.MyInterface)$*

Answer 1

您应该能够使用以下条件保留规则：

-if class com.example.** implements io.foo.bar.MyInterface
-keep class com.example.<1>$*

如果软件包com.example中的类实现了io.foo.bar.MyInterface，请保留其所有内部类。

避免混淆R8：内部类或接口，外部类在其中扩展或实现
