I’m using Solar2d to build a character sheet app for an RPG. I save each sheet’s data as a json file, but as cross-device play is important, I’d like to be able to regularly save and retrieve these files from a system folder (which is linked to a cloud server, i.e. dropsync or drivesync).
pathForFile doesn’t let me escape the base directory of the file, which is not only inconvenient on a desktop, but apparently impossible on an Android.
Is such a thing possible, or am I screwed?
On Android and iOS, you should stick to using the Documents directory.
On Windows/Mac, you could also use documents directory, but if you want to save the files wherever you want on your computer, you can do so. If you run print( system.pathForFile() ) you see that it returns the project root path, but when you’re reading and writing files using io.*, for instance, you can just type in any filepath that you want (as long as you have read/write access).
You also have full access to os.execute and Lua file system, so you can do pretty much whatever you want with files like that.
I was recently looking into it as well for a personal Android app, even also planned to use dropsync/drivesync, and this plugin by @Scott_Harrison is probably our best bet on Android:

Sadly I haven’t had the opportunity to test it myself yet due to a lack of time, but I’ve talked to Scott and there don’t seem to be any issues when it comes to our use case, at least in theory.
Hope it helps!
Hah, I saw that too. Gonna try it out tomorrow, I’ll update you on my findings.
After battling with the demo for a bit, I finally got it to not-work on my devices - Specifically the “make a folder” and “copy to SD” buttons/functions don’t actually do anything, although the former incorrectly returns a popup saying it’s successfully created a folder (it hasn’t, I’ve looked). sdCardPath returns a string (“no access”), and then contradicts itself by saying isWriteable.
Can’t recommend, unfortunately.
