How to organize sending and receiving files to the server in an Android application?
It is the server part that is of interest, preferably on Laravel. There is not much experience, so detailed comments are welcome.
Wrote a PHP server in Laravel. It contains a regular page that contains the "Upload file" form and saves the received files to the server. But it seems to me that this is not it. There will be many connections and files. Approximate size up to 1 MB.
