창이 전체 요청 할당 오류입니다.

Question

두 가지 서비스 중 하나는 센서를 사용하고 다른 하나는 GPS를 사용합니다. 하나의 데이터베이스가 있습니다. 나는 그것들을 결합 할 때 평균 센서 값을 얻고 그것들에 GPS 라인을 쓴다. 평균을 얻으려면 DB를 계산하십시오. 그러나 잠시 후 응용 프로그램이 작동하지 않습니다. 그것은 그 오류를 제공합니다.

인용문 W/CursorWindow (2852) : 할당 228 바이트, 여유 공간이 156 바이트, 창 크기 2097152 바이트 인용문

캐시 또는 뭔가를 취소 할 수있는 가능성이 요청 : 윈도우가 가득 ?
