It seems that with these Wifi APIs the app could find out if the device
is connected to a wifi or not:
https://developer.mozilla.org/en-US/docs/Web/API/WifiManager
https://developer.mozilla.org/en-US/docs/Web/API/WiFi_Information_API
So there could be a checkbox in the app (much like for the ownCloud
Android app) to »Upload only on Wifi«.
As for uploading: Does the camera also have an API which might fire off
events when a new photo is taken? You could hook into that, and for the
first iteration just upload pictures directly.
David, do you have any pointers here – how does the ownCloud Android app
handle it?

Hello oC developers,
I'm currently building a Firefox OS mobile app that automatically
backs up photo and video media from the device to ownCloud. Since this
is my first time developing for mobile, I'm unsure of the best way to
handle automatic photo uploads.
My initial idea was to check device storage every few hours and upload
any new media to ownCloud. I'm not sure if this is the most effective
manner of handling this. I know that the Google Plus backup on my
phone, for example, uploads my pictures in batches. However, I'm not
sure how it decides when to check for new photos and when to upload.
(Should the app also, for example, wait until the user connects to
wifi to upload the media? I am not sure how I would access this
information on Firefox OS.)
If anyone could offer general advice regarding syncing from mobile
devices, that would be great. I'd love to hear from other developers
who have experience implementing similar functionality.
Thanks,
Lyndsey
