For the game that we are currently working on, we utilized the example provided to save/load config files. We have not been able to write/save to this file, unfortunately. I've tried adjusting the code/filename to point to the readonlypath but this has not been successful, either. I am making an assumption, but I figure this will be an issue later on as well when we port to iPhone.
Has anyone figured this out, specifically, how to save files to the android in a manner that maintains cross-platform portability (specifically for iPhone)?
