안드로이드 - 로그에 IOException 오류

Question

나는 이상한 상황으로 고통 받고 있습니다. 문제는 내 응용 프로그램이 Asynctask를 사용하여 사용자 정의 웹 서비스에서 데이터를 가져 오는 것입니다. 동일한 작업에서 로그에 IOException 오류가 발생합니다. 그러나 작업이 잘 작동하고 서버에서 수집하는 데 필요한 모든 데이터를 반환합니다. 의미하면서, 그것은 asynctask 잘 작동하지만 "IOException"을주는 로그에있는 것 같습니다. 여기에 로그가 있습니다

여기 내 Asynctask.

안드로이드의 가비지 콜렉터는 백그라운드에서 실행됩니다. DVM은 GC를 호출하고이 특정 응용 프로그램에 할당 된 RAM을 늘려 불필요한 데이터를 삭제합니다. RAM은 응용 프로그램에 제공 할 수있는 최대 RAM에 도달 할 때까지 증가하고 이후에도 확장하려면 DVM에서 Out of Memory Exception을 발생시킵니다.
