我正在尝试使用 sqlite 将信息添加到我的 firebase。我已将 Order.db 数据库文件添加到我的 Assets 目录中，但仍然收到此错误。我对编程有点陌生。

最佳答案
I have added Order.db database file to my assets directory but am still getting getting this error. I am a bit new to programming.
您需要将Order.db数据库文件添加到assets/databases目录(创建目录后)，如下所示: -
SQLiteAssetHelper relies upon asset file and folder naming conventions.
Your assets folder will either be under your project root, or under src/main if you are using the default gradle project structure. At minimum, you must provide the following:
- A databases folder inside assets
- A SQLite database inside the databases folder whose file name matches the database name you provide in code (including the file extension, if any)
关于java - 无法打开sqlite数据库，指定的目录或数据库文件不存在，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58664284/
