刚在我的游戏机中看到一个报告:
android.database.sqlite.SQLiteDatabaseCorruptException:

有人知道应对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。同样，重现此内容的好方法是什么-那么如何优雅地破坏数据库？
最佳答案
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，请参阅此文章:Android: Check if a file is a valid SQLite database
编辑:好的，it seems it's possible to fix a SQLite database，但这实际上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。
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)。可能这将损坏文件，并且您将获得
