안드로이드 쓰기 실패 : ENOSPC (장치에 남은 공간 없음)

Question

나는 사용자에게 보여줄 pdf 파일을 다운로드 한 후 다운로드 할 수있는 listview가 있습니다. 하지만 내 logcat에 오류가 발생하여 앱이 제대로 작동하지 않습니다. 포럼 및 다른 stackoverflow 솔루션을 읽었지만 내 문제가 해결되지 않습니다. 미리 답변 해 주셔서 감사합니다.

내 로그 캣 오류 :

장치의 내부 저장 파일 시스템에 남아있는 메모리가 충분하지 의미 자세한 내용은 내 수업을 붙여 넣습니다. 이게 도움이 될 것 같아요
