如何从sqlite db加载超过1MB的数据到android游标?
确切地说,我正在尝试将超过 1MB 的数据从 sqlite 数据库加载到 android 光标。在加载时,它会出现以下错误,例如
08-04 11:10:15.813: ERROR/CursorWindow(4465): need to grow: mSize = 2097152, size = 403719, freeSpace() = 209669, numRows = 1
08-04 11:10:15.813: ERROR/CursorWindow(4465): Attempting to grow window beyond max size (2097152)

是否有人知道如何将大数据(超过 1MB)加载到 android 光标? 谢谢,

不要在数据库中存储 500KB 的 blob。将标识符存储在数据库中并将 blob 作为文件放入存储中。如果使用 MODE_PRIVATE,其他进程将无法访问它们。
Don't store blobs of 500KB in your database. Store identifiers in your database and put the blobs as files onto the storage. If you use MODE_PRIVATE, they will not be accessible by other processes.
