Question

当我尝试从管理站点访问PayPal IPN时出现此错误。

E/AndroidRuntime: FATAL EXCEPTION: main
                  Process: com.none.myapplication, PID: 3881
                  java.lang.RuntimeException: Unable to start activity ComponentInfo{com.none.myapplication/com.none.myapplication.MainActivity}: java.lang.IllegalStateException: attempt to re-open an already-closed object: SQLiteQuery: SELECT  * FROM oldDetails

我使用Google Mysql，我已经在Google Cloud Shell上尝试了这个答案solution1。

实际上你用Google搜索的解决方案应该正常工作，但是你做错了。

我会在这里再次展示它们，但为了澄清，以下步骤都是从问题描述中复制的。

步骤：

在系统命令行而不是MySQL的命令行界面中，键入 mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -D mysql -uroot -p，所以你会看到类似的东西：
```
ubuntu@ubuntu$ mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -D mysql -uroot -p
```
（可选）检查问题是否已解决。如果没有，请在系统中按mysql -uroot -p输入 MySQL命令行，然后键入flush tables;。您的屏幕将如下所示：
```
ubuntu@ubuntu$ mysql -uroot -p
Enter password:
...
mysql> flush tables;
```

数据库在QuerySet.datetimes（）中返回了无效值
