Hey,

I think this wasn't a problem in the past because we could easily use std::fstream (or C API) to write to files, but with the mobile ports things have changed, at least on android you cannot use std::fstream and the C API only limited. So wouldn't it be nice to have a platform indipendent API to write files?

You can't use fstreams on Android? Really?

Anyway, SFML uses the standard library for its file streams it wouldn't solve anything...

On android there is a special ResourceStream for inputstreams implemented in SFML, the same could be done for Outputstreams. C File API for every platform except android where you have to use AAssetManager, which has basically the C File API with different names.

Ah. I didn't know about it.

I messed something up in my head. Writing files is actually possible with the C-API (idk if streams are implemented yet, during kroniax dev they weren't) but you need to get the path of the internal storage from your app, because the working dir is inside the apk and you cant obviously write into the apk. And to get the path you need the ANative_Activity -> Issue: https://github.com/SFML/SFML/issues/680
Mario is already working on it

Another possibility is to expose standard paths (app data, temp directory, ...) to the user. I think we already discussed this feature but I don't remember what was decided.

Nobody was really against it, but we didn't get to a concrete API yet. I suggest we continue the discussion about standard paths in the linked thread, as this one is about output streams.

"Standard paths" would be something for static members in a possible file-system implementation I guess. So no real extra work to be done, it's just a tiny feature to add to an even bigger feature that's planned.
