Are you saying you open A then open B, press the back button to return to A then do whatever it is you did the first time to get back to B? If so B will be re-created with a brand new Intent which will contain whatever you stuffed in there. > I want to resume the activity B (which has a Bundle passed to it ) from > Activity A. > What do you mean you want to "resume" B? If you've gone to B and pressed back to get back to A, B is gone. It will recreated, not resumed. > The documentation says that OnSaveInstance() is called only when the > activity is killed, > Not just that it's killed - when it's killed by the system and may potentially need to be restored - like the user pressed the Home key. If you press back or intentionally finish the activit, onSaveInstanceState is not called. > so how do i use OnPause which does not have the Bundle to resume the > activity B. > You don't. If you're trying to do what I think you're trying to do you might: In A, start B with startActivityForResult(). In B, when pausing call setResult() with state information for B. In A, onActivityResult() get the result Intent and save it for later. When restarting B if you have the previous state information for B, pass that in to the Intent for B. In B onCreate get the Intent and get the state information from it, if it exists. Hope that helps.
