[MalitsPlus]

？没看懂你想做什么

[MalitsPlus]

你是说你想手动拷一个数据库文件到app的内部文件夹？

[Kanata03]

额就是我需要特定版本的数据库，但是我在没root的情况下我只能读取最新版本的db

另外目前最新的数据库国服我手机提示加载错误

额就是我需要特定版本的数据库，但是我在没root的情况下我只能读取最新版本的db

参考 #50
没 root 的话可以把这个 repo 克隆下来用 Android Studio 编译一个 debug 版本的 apk（或者直接连接手机 debug）然后把数据库文件往 /databases 里面拷就行了，debug 版本的 app 不需要 root 权限就能访问内部文件。

I have one solution. Just leave this idea to whom really want to implement it.
I really do not recommend implementing it in this project, @MalitsPlus, because it can yield many unwanted errors or exceptions as I have already faced.
Just consider below if you are interested and are working with a forked project.

• Add the 'Custom DB' option in the server selection.
• Implement a DB file loader fragment somewhere in the setting.
  • This advanced function lets you easily load the custom DB file from your file system.
• I also recommend implementing the checking system whether it is valid sqlite3 using the first few bytes.
• Please turn off the update DB service for this server(?).

If you are interested in this function but do not know how to implement it, you can freely refer to some commits of my KR version of the ShizuruNotes, the KasumiNotes project. However, DO NOT USE redive_cn.db for a test in my app because it crashes instantly.
I also will not attach a link or directly refer to my commits here because my project goes so far away from the original ShizuruNotes, so I just leave the idea.
