ProGuard: keep private Inner Class

Question

How to keep private Inner Class in ProGuard. I am already using($ for inner class) below code in my proguard.cfg but its not working.

-keep public class com.xxx.droid.activity.LoginActivity$JsInterface

I know this is old - may not get seen. Having a similar problem but the answer gives me a proguard error 'unknown class' — Brian Reinhold, Sep 21 '21 at 13:09

This should work:

-keep public class com.xxx.droid.activity.LoginActivity$* {
        *;
 }

If the inner class is private, you shouldn't use the public keyword in the template, because it won't match. The compiler will actually compile the class as a package visible class (private classes don't exist at a bytecode level). Therefore:

-keep class com.xxx.droid.activity.LoginActivity$JsInterface
