>>underlying Activity (which has life cycle implications for the >>underlying Activity).
Precisely why you would want to use an Activity. And a Dialog is in no way restricted in it's layout. You can put in any component inside it, and access it as well. Moreover, dialogs don't have the same lifecycle events as the activity. Dialogs can be basically used for providing confirmation messages, prompts and also used for taking in small inputs from the user. All this, of course can be done by using an Activity, but creating a whole new activity will be an overhead if it's just to display a confirmation/prompt or asks for 1-3 inputs from the user.
