Hi Prajakta, By default, an activity will be "destroyed" (onDestroyed() will be called) being called when the "back" button is called. E.g A calls B, and user presses the "back" button, then activity B will be destroyed. So from calling activity B again from activity A will create a new instance of activity B (onCreate() will be called).
So if I understand you right, you would like to use the same instance of Activity B instead of recreating a new instance each time the Activity is called from other activities. Therefore, you *might* want to use "singleTask" as the Activity's "launchMode". You can find out more information from here. http://developer.android.com/guide/topics/fundamentals.html#lmodes On Mar 13, 9:25 am, Prajakta Shitole <[email protected]> wrote: > Hi Jeffrey, > > Thanks for the suggestion but I have activities and not views.
