this is the first time I'm taking a look at the Dropbox API so I'm afraid I kinda don't understand much.
My purpose is to develop an App in which I place some files into a directory so as to be automatically uploaded to the server and synced in another device whose owner I'm sharing them with, so different accounts are being used of course.
In the end, it has to be something similar to Dropbox app itself: you are able to create a file, upload it and share it with some friends.
Any idea if this is possible, what to begin with, is it possible to use for this goal any folder i want or it has to be one particularly chosen by Dropbox...?
