I’m currently working on cloud save for a game on android. The tutorials online have worked pretty good (although a couple of hidden pitfalls), but one point that is never touched is what happens after you’ve loaded a save. I’m assuming this means it really doesn’t matter, but googling it gave no results, so I figured I should put my experience online if nobody already has.
In short, opening a file that is already open will not immediately fail, however I can’t speak for memory leaks or other more hidden issues.
