What is the validity of the access token granted by Dropbox API (OAuth v1) and how to refresh it?

Question

I read a thread on the dropbox forum here. But I'm still confused as for how long the token is valid and do I need to refresh it and how. My application needs to perform some scheduled operations on the users files offline, so I need to have a longer access, say for a week without the need of the user being asked to grant access again.

Answer 1

The Dropbox API Authentication Tutorial would seem to indicate that access tokens are valid until the user uninstalls your app, or explicitly revokes the grant via the Dropbox page.
