问题
I'm using this answer: https://stackoverflow.com/a/18739812/2904688 to split my android app into an APK and ZIP and it works like a charm.
Although the app launches properly all sounds are not playing. Cocos2dxMusic.java & Cocos2dxSound.java seem to not be able to read the sound files in the zip. All assets (images, animations, etc) load correctly but the sounds (music & SFX) seem to not load.
The relative to the assets.zip path is correct as given by the logs. Any clues? I am using cocos2d-x 2.2.0
Here's the error codes thrown:
