How to initialize an activity from another activity

I have activities A and B. Activity B is started by a service while the application is closed and activity A is not on the stack. Activity A has members that B requires access to. I would also like the home button to open activity A from Activity B even if activity B is started from a service. Is there a way to inject activity A back into the stack?

That won't be a good decision, better use the members in the B Activity and Once Activity B is launched and it's about to leave just give intent to Activity A. Also you can check if Activity A is already in the stack. If already in the stack, it will popup by itself, if not found, can pro grammatically trigger it.

In your Service start ActivityA not ActivityB and pass some parameter to ActivityA.. and in ActivityA's OnCraete method launch the ActivityB.. now you have both in the stack.

You can declare the logical parent of each activity in your manifest file, using the android:parentActivityName attribute (and corresponding element),for home button working.

And to add a activity back to stack Check this link for more details.
