Sending Activity to background without finishing

Question

How can I make an activity go to background without calling its finish() method and return to the Parent activity that started this? I tried so much but I could

Moving the task backward is NOT going to insure that you will maintain any state, unless you do that manually by responding to the Activity lifecycle events.

You should just start the second Activity via Intent using startActivity(), or, if you need to receive a result back from the second Activity, use startActivityForResult(). This allows you to receive a callback when the user finishes the Activity and returns to your first Activity.
