There are probably a few other ways to do this. If the user goes away from your app, and android doesn't shut it down, then comes back, the user should still be logged in right? As Mark said, onResume() is where you can figure this out.
Another way is to use SQLite or something to store a session token and in onResume look it up and check the timestamp of when it was stored (you'd put that in your onPause..storing it with timestamp). Then, if the timestamp is < some amount of time, continue with it.. if not, invalidate and take to login screen. Any form of storage could be used for this.. since a phone is a single user device, you could store a file like a lock file, etc. On Thu, Feb 10, 2011 at 1:56 PM, Mark Murphy <[email protected]>wrote: > On Thu, Feb 10, 2011 at 4:53 PM, Hari <[email protected]> wrote: > > There are 2 possibilities, > > 1. you come back to the same screen (activity) due to the application > > flow.
