A small project to create a SyncAdapter framework linked to a restful website, (not Google/Parse etc)
I'm pretty open to ideas on the web server, however jetty seems to be a reasonable choice.
The app will be able to sync the phone contacts and a local database to the server.
Ideally some user authentication would be included and the sync information wouldn't be shared across accounts.
The Google sample [url removed, login to view] would be an excellent starting point as it's mostly just the auth/web server and contacts sync that need to be added.
