Question

在我的游戏机上看到一个报告：

android.database.sqlite.SQLiteDatabaseCorruptException:

有人知道处理这些问题的好方法吗？尤其是在使用LiveData时，我还没有找到解决此问题的好方法。另外，重现此内容的好方法是什么-那么如何优雅地破坏数据库？

有人知道处理这些问题的好方法吗？

好吧，如果您的数据库已损坏，则它已损坏。除非您从头开始重新创建它，否则可能无法修复它。但是，如果您想在进行任何操作之前先检查它是否有效，只需参考这篇文章：Android: Check if a file is a valid SQLite database

编辑：好的，it seems it's possible to fix a SQLite database确实取决于它的损坏程度，因此您可能不会编写通用代码来修复它们。

还有什么是重现此事的好方法-那么我该如何腐败数据库优雅吗？

您将不得不在有根电话上重现它，因为您将无法通过标准SQLite语句破坏数据库（特别是为了防止这种情况）。

拿一个虚拟电话（或仿真器），然后将其root，然后访问此文件：

//data/data/<Your-Application-Package-Name>/databases/<your-database-name>

您可以使用任何编辑器将其打开，然后将其弄乱（删除几行然后保存）。很有可能这会损坏文件，并且您将获得SQLiteDatabaseCorruptException

Room和SQLiteDatabaseCorruptException
