“Configuration change 발생 시 MapView로 인한 메모리 누수가 발생합니다”

카카오맵 API (지도/로컬)
1

안녕하세요.

지도를 사용하는 화면에서 Configuration change 발생 시 메모리 누수가 발생하는 현상을 확인하였습니다.

onResume/onPause 시점에 맞춰 MapView.resume(), MapView.pause() 또한 잘 호출하고 있는데, 어떤 원인으로 해당 문제가 발생하는 것인지 알 수 없어 이렇게 여쭙습니다.

감사합니다.

Configuration change 상황이라고 하셨는데, 올려주신 로그를 보니 destroyed activity 를 참조하여 발생한 메모리릭으로 보여집니다.

  1. Configuration change 시에, 액티비티가 매번 destroy 됐다 새로 생성되는 구조인 것이죠?
  2. 그렇다면, MapView 는 하나의 Activity 에 종속적이므로, Configuration change 가 될 때마다 지도가 제대로 종료되고 새로 생성되는지 확인이 필요하고 이 과정에서 MapView 객체를 Activity 라이프사이클을 벗어나서 어딘가 저장되어 있지 않은지 확인이 필요합니다.
  3. 디버그 모드에서 문제의 상황(Configuration change 발생)을 재현시키시고 “k3f” 로 필터링 된 로그캣 로그 첨부 부탁 드립니다.

우선 MapView#finish 함수를 직접 호출하여 메모리 누수를 방지하였습니다.

다만 finish 함수는 Activity가 종료될 때 자동으로 호출되는데, 해당 에러가 왜 나는건지에 대해서는 알 필요가 있을 것 같아 로그 첨부드립니다!

올려주신 로그는 지도가 시작(start) 시에 나오는 정상적인 내용들입니다. 아래의 로그는 무시하셔도 괜찮습니다.

ImageAsset is invalid. unsupported image format.

혹시, 지도를 종료했는데도 위의 로그가 나오고 있다면 지도가 어디선가/어떤 부분에 의해 다시 실행된 걸로 보여집니다. 이 부분을 살펴보시면 좋을 것 같습니다.
