In Android, from Activity A, if I start new Activity B, Android will automatically

  • 0

In Android, from Activity A, if I start new Activity B, Android will automatically save all the state of Activity A. So when I click back or call finish() from Activity B, Activity A will be restored to the state when I start Activity B (for example: position of a ScrollView in Activity A, or the value of ProgressBar). In Activity A I have a ProgressBar showing progress of some task, then if I come back from Activity B, the ProgressBar is restored and keep running.

Now what I want is, from Activity A, I will call finish(). How can I save all the state of Activity A just like Android did (include the ProgressBar as I describe above), so when I start Activity A again, I can restore everything like before calling finish(), and my ProgressBar keep running?

Can I push Activity A to something like stack in Android and then pop it out? Anyone know how to achieve this?

    Do not call finish on clicking the back button.

    Instead call the method “moveTaskToBack(false)”. This will ‘minimize’ your application.
    Next time you open the application the application opens with the previous state.
