仅从playstore更新后Android应用程序崩溃

我最近更新了1.2版，因为我使用内置数据库来显示数据。我第一次从资产中复制了数据库，并使用ContentProvider访问数据库中的数据

它在第一次安装时工作正常，但如果任何用户从playstore更新应用程序，就会出现错误

用户报告的错误日志：

我并没有在新的更新中更新数据库版本，我尝试了很多来寻找，但不知道为什么它只在更新应用程序后发生

---

有人能帮忙吗？提前感谢。

我认为您没有为数据库提供正确的更新脚本。如果应用程序是从头开始运行的（即没有现有数据库），这将正常工作（因为不需要数据库迁移）

研究SQLHelper类，它们提供了允许您迁移数据库版本的方法

需要说明的是，您需要更新的是数据库模式，而不是数据（模式中缺少一列，错误指出该列）：

我不会在任何更新中更新数据库，因为它只是第一次复制。我不会在任何更新中更新数据库，因为它只是第一次复制。您是如何进行复制的？如果有什么不同，你是做错了。你是怎么复印的？如果有什么不同，你是做错了。
