activity

I have an activity which pulls some JSON from my server, and then uses it to draw a list. That list launches further activities.

My problem is that I can't figure out a way to tell if the activity is still alive when you go back to it, so I end up re-querying my JSON from the server and redrawing the list every time the user goes back to the activity.

How can I tell if my activity is still alive so I can skip the redraw?
