Is Activity accessible or visible to the user after transitioning to the onStop state?

After transitioning an Activity to the onStop state, it is not visible to the user and is not on the foreground. In this state, the Activity is completely hidden but not yet destroyed. It can be resumed and transition to onRestart, then to onStart and onResume if the user returns to it.

Thus, after onStop, the user does not see the Activity, but it still exists in memory, allowing for a quick interface restoration if needed.
