I'm in the testing phase of my game, and I've noticed that when I update the app to a new version, save files can be erased. This is kind of terrifying, because if this happened to a live copy of the game I'd have people losing their progress. My method of saving is to write a ds_map to an .INI file. I do this to make hacking save files more difficult. I'm hoping this save file loss is just a glitch, but I want to do everything possible to ensure that I'm using the best method possible to save progress. How do you save progress in your Android game, and have you experienced any save files being lost?
