We've already been having this discussion in another thread. If you want to retain some state in your activity -- even across the user pressing back to finish your activity and then later launching it again -- then just save that state, in whatever way you want, in onPause().
If you want to let the user have some background thing of your app going on while the user is not in its UI, you can have in your UI a facility for them to explicitly start and stop the background work. That is not the same as them quitting your app. On Thu, Sep 3, 2009 at 1:09 AM, Ne0 <liamjamesalf...@googlemail.com> wrote: > > Dianne, > > If there is a more appropriate way of doing this please advise. > > My activity, starts, stops and binds to a service.
