Ok, thank you for the hints. In my case, I display a subactivity in form of a dialog for entering connection settings. Pressing "back" returned to the main activity that reconnected with the new settings.
So I guess the best is to introduce the "OK" and "Cancel" buttons, and have pressing "back" meaning "Cancel" in a dialog, right? (so the edit- in-place model really applies only to main activities, and not to dialogs as I mistakenly assumed...)
