In which scenario would the onStop() method be executed for an activity?

The onStop() method is called when an activity is no longer visible to the user, marking a crucial point in the activity lifecycle. This method can be triggered in various situations, such as when another activity is brought to the foreground, which makes the current one invisible. It's important to recognize that this method ensures the activity can properly handle resources and data at this point since the user cannot interact with it anymore.

When considering other scenarios, if another activity comes to the foreground, it might lead to the onPause() being called first, followed by onStop(), but not directly trigger onStop(). When a dialog is shown, the activity is still visible and is typically in the paused state, not stopped, which means onStop() does not execute. Finally, destruction of an activity invokes onDestroy(), following the sequence of onStop() and onPause() if the activity is being closed rather than simply becoming invisible.

Therefore, being no longer visible signifies a more conclusive state, directly invoking onStop() to manage the activity's resources and prepare for potential return or complete closure.
