Well, that was a waste of time. Raccoon and Google Play communicate with each other by exchanging protocol buffer files (think: binary XML). The problem with protocol buffers is that Android only supports 64k methods per DEX file and the protoc compiler exceeds that limit effortlessly. Of course, Android also offers a dirty hack to put more than one DEX file in an APK, if you are willing to bundle yet another compatibility library. I’m not, so I thought that switching to java-proto-lite would be a good idea. Lo and behold, the proto parser code shrunk by a magnitude! Sadly, the lite runtime doesn’t work with the proto2json export library. So yeah, lean code or being able to cleanly export pb to json. Tough choice.
