I’ve managed to successfully port Chirp Chirp from cocos2d-iphone to cocos2d-x. I also had problems with anything to do with plist files. I wound up writing my own implementation for reading them, using tinyxml instead of libxml. Most of the crashes seemed to be happening inside libxml.
Are you able to load you 8000-frame sheet using the win32 version of cocos2d-x? If so, i’d imagine the engine can in theory handle it. If you’re getting android-only memory crashes, maybe you’re just using too much memory for your device?
