흔들면 SoundPool 재생 오류가 뜨네요 ㅠㅠ

뭘 빼먹은게 있을까요? 로그에서는

코드를 http://www.masterqna.com/android/1 로 올린 거 맞나요?

Answer 1

로그라도 제대로 올려주시던가 중요한 부분은 다짤리게 올리고 날짜랑 시간 패키지명만 올려주면 어떻게 알아요 내용은 다빼고 날짜 만 보여주고 이런 문제가 있는데 어떻게 해야하죠 이러면 누가 알아요

스크롤바가 안 나와서 그러는 것 같아요. 어떤 분들 보면 저렇게 나오던데, 뭘로 올려서 그런지 모르겠네요.

Answer 2

onSensorChanged 에서 SoundPool을 매번 new 하던데, 생성하다보면  OOM 나올 듯 한데요..

load까진 onCreate 같은데서 하시는것이 좋을 듯 하며,

흔드는 이벤트가 엄청 들어올 수 있으니 onSensorChanged 에서는 핸들러 sendMessageDelayed 같은 것으로 ,  

이벤트만 핸들러로 넘기고 핸들러에서 play 하게 변경 해 보시는게 좋을 듯 합니다.

 

또한 화면 회전을 막아 두신 건지 확인 해 보세요. 회전이 되면 매번 onCreate, onsStart, onStop가 불려 꼬일 수 있을 듯 합니다.
