Proguard - how do you know what modifications to make to to the proguard file based off the jars and libraries you use?

Question

I am having some troubles with Proguard. When I enable Proguard and then try to sign my application package, I get the following errors in my console:

Proguard returned with error code 1. See console

       You should check if you need to specify additional program jars.
 Warning: there were 36 unresolved references to classes or interfaces.
          You may need to specify additional library jars (using '-libraryjars').
 Warning: there were 1 unresolved references to program class members.
          Your input classes appear to be inconsistent.
          You may need to recompile them and try again.
          Alternatively, you may have to specify the option 
          '-dontskipnonpubliclibraryclassmembers'.
 java.io.IOException: Please correct the above warnings first.

How do I dictate what modifications I need to make to my Proguard file to sign my application successfully? If anyone could help me out, that would be highly appreciated.

I recommend searching this repository https://github.com/krschultz/android-proguard-snippets in order to find proguard configuration of a library that you use. — dawid gdanski, Jul 05 '15 at 09:01

I think it depends on libraries you are using.

Try this:

-keepnames class com.jakewharton.disklrucache.** { *; }
-keepnames interface com.jakewharton.disklrucache.** { *; }
-dontskipnonpubliclibraryclassmembers
