탐색 세션이 완료되면 Navigator#clearDestinations 및 Navigator#cleanup 사용
메모리 누수를 방지하고 적절한 정리를 보장하려면 탐색 세션이 완료되고 Navigator 인스턴스가 더 이상 필요하지 않은 후 Navigator#clearDestinations 및 Navigator#cleanup를 사용하세요. 이는 사용자가 지도에서 벗어났을 때와 연결된 활동의 onDestroy()가 호출될 때 실행할 수 있습니다.
더 이상 필요하지 않은 GoogleMap 요소 정리
앱이 탐색 이외의 지도 환경에 GoogleMap 인스턴스를 사용하는 경우 더 이상 필요하지 않은 인스턴스를 정리해야 합니다. 예를 들어 Polygon#remove, Polyline#remove, Marker#remove 메서드를 각각 호출하여 GoogleMap와 연결된 다각형, 다중선, 마커 요소를 정리합니다. 그런 다음 더 이상 필요하지 않은 GoogleMap 인스턴스를 해제하려면 GoogleMap#clear를 호출하여 인스턴스를 null에 할당합니다.

This can be\ndone when the user has navigated away from the map and when `onDestroy()` of the\nassociated activity is invoked.\n\nClean up `GoogleMap` elements when they are no longer needed\n------------------------------------------------------------\n\nIf your app uses a `GoogleMap` instance for non-navigation maps experiences, be\nsure to clean up this instance when it is no longer needed. For example, clean\nup the Polygon, Polyline, and Marker elements associated with `GoogleMap` by\ncalling the `Polygon#remove`, `Polyline#remove`, and `Marker#remove` methods,\nrespectively. Then, to free up the `GoogleMap` instance after it is not longer\nneeded, call `GoogleMap#clear` assign the instance to `null`.\n\nFor more information about using a `GoogleMap` instance in your app, see\n[`GoogleMap` interaction best\npractices](/maps/documentation/navigation/android-sdk/googlemap-interactions-best-practices)."]]
