Android: Keep multiple instances of an activity in the back stack

Question

I have an Activity A from which I start Activity B. In Activity B I want to start a new instances of B (with different contents), so that I can navigate back to different instances of B. For example:

A -> B (with content x) -> B' (with content y) -back-> B (with content x)

My problem:

For an example navigation path:

A -> B -> B' -> B''

when pressing back in B'' I return to A and not to B' as expected. Doesn't android store instances of an activity in the back stack or do I have to do something to tell android to save every single instance so I can navigate between them?

Answer 1

You should read Google's Tasks and Back Stack document.
