Solved it. I was able to find a working solution reading: How to make Proguard ignore external libraries?. I added the this to my proguard file:

-keep class javax.** { *; }
-keep class org.** { *; }
-keep class com.afollestad.** { *; }

The last one is most imortant, it's the entire theming library where some classes couldn't be found.
