I am looking for a way to Initialize all my game activities once and switch between them when needed. Is it possible if so how? How can I bring an Activity to front from another Activity without Initializing it again and not finishing the calling activity?

This is not possible with activities.

However to make it possible you could use fragments instead of activities, which is recommended to use anyway.

  • You can not make Activities alive in background. You always have one activity loaded and that's the one in the foreground. – ramdroid Feb 07 '12 at 12:34

  • the problem is that when ever we close an activity Suppose A and goto B from A and then switch between A and B. The memory taken by these activities is not released on finishing them thats what make the application run slow.Starting a new activity will be assigned new memory..... – Jawad Amjad Feb 08 '12 at 05:10
