Android proguard, keep inner class

Question

My android program has a class A, which has two static inner class. They are found to be stripped from .dex after applying proguard.

public class A{    ...   static class B{     ...   }    static class C{     ...   } } 

I have put the following lines in proguard.flags, but seem no luck.

-keep class com.xxx.A -keep class com.xxx.A$* 

Any hint?

Answer 1

Try adding InnerClasses to the keep attributes. e.g:

-keepattributes Exceptions, InnerClasses, ... 

Also, try adding a body to the "keep" call with an asterisk, like so:

-keep class com.xxx.A$* {     *; } 

Answer 2

This is what I had to do for my config

-keep class com.xxx.A { *; } -keep class com.xxx.A$B { *; } -keep class com.xxx.A$C { *; }
