有什么方法可以从本地计算机（本地服务器）读取数据库文件并复制到 android 中的资产文件夹？

Question

@Singleton
@Provides
fun provideDB(applicationContext: Context): myDB{
    return Room.databaseBuilder(applicationContext, myDB::class.java, DatabaseConstants.DATABASE)
            .createFromAsset("sample2.db")
            .fallbackToDestructiveMigration()
            .build()
}

This is my code in which I am reading sample2.db from the assets folder. I want to read it from the local server and paste it to the assets folder so that I can use it the way I am using it during runtime. The app should read the file from the local server and paste to the assets folder or update the file if already present.

Answer 1

You cannot copy something into the assets folder at runtime if that is what you are asking. You will need to download the file then store it in the file system at runtime
