앱개발 질문

갤럭시탭 7.0에서 만든 프로그램을 갤럭시탭 10.1로 바꾸는 과정에서

생긴 오류입니다. (오류파일첨부함)

소스는 고치지 않고 레이아웃 xml 부분만 수정했구요.

화면1에서 화면2로 넘어간 다음 다시 화면1로 back 하려고 하니 저런 오류가 납니다.

갤탭7.0에서는 오류가 안났었구요.

아래에 소스 첨부합니다.

건방진프로그래머

쿼리날리셨을때 cursor.close()를 제대로 안해주셨습니다..........................

아 보니까 저기에 Cursor이 있군요

그럼 finally 구문 넣으셔서 cursor이 null이 아니면 닫아주기 구문 넣어주세요 ~~curosr에 null 넣어주심 더 좋고요

안드로녀

건방진프로그래머 님 말씀대로 다시 우아한 방법으로 해야겠네요 ^^

저는 화면2소스 중에 69 라인인 startManagingCursor(cursor); 이 부분을 주석처리 해버리는 꼼수를 써서 해결을 했었어요.

고맙습니다~

역시나 좋으신 분들이 많군요 ㅠ.ㅜ
