Question

我的问题与此one非常相似，但略有不同。当我只是尝试查询我的表中已由SQLCiper加密的所有内容时，我收到以下错误。

 12-29 11:37:54.329: E/Cursor(10837): Finalizing a Cursor that has not been deactivated or closed. database = /data/data/com.company.myapp/databases/data, table = data_table, query = SELECT rowid, data FROM data_table

我认为只有在我完成使用后忘记关闭Cursor时才会出现此错误，但似乎即使在我开始使用它之前我也会收到此错误。< / p>

以下是queryAllItems()方法中的代码：

public Cursor queryAllItems() {
    return database.query(DATABASE_TABLE, new String[] {KEY_ID, KEY_DATA}, null, null, null, null, null);
}

Answer 1

我被堆栈跟踪误导了，看来我只需要在完成对查询的所有操作后调用Cursor.deactivate()和Cursor.close()。

Answer 2

创建光标后，如果致电startManagingCursor(c);将解决问题。这里'c'是游标引用。

SQLCipher - 完成尚未停用的游标错误
