데이터베이스 안드로이드 sqlite에서 닫히지 않은 오류

Question

내 전체 응용 프로그램이 잘 실행되고 있지만 로그캣을 볼 때 MyDBinstance.close() 문으로 데이터베이스를 닫은 후에도 데이터베이스와 같은 오류 메시지가 표시되지 않습니다. 그들은 왜 다시 오나요?, 제 신청서에 해롭지 않습니까?

Answer 1

당신은 당신이 항상 커서를 닫습니다 확인하기 위해 다음과 같이 수행 할 수 있습니다 :

Cursor c = null; 
try { 

    c = somehowCreateACursor(); 

} finally { 

    if(c != null) { 
     c.close(); 
    } 

} 

Answer 2

데이터베이스를 종료 할 필요는 실제로 없다. 심지어 위의 명시된 예외가 발생할 것이라는 사실 후에도 그것은 결코 어떤 식 으로든 응용 프로그램에 해를 끼치 지 않을 것입니다.
