Answer 1

setDestinationInExternalPublicDir(dirType: String!, subPath: String!)

For applications targeting Android 10 and above, the first parameter dirType for this method must be one of the known public directories like Environment.DIRECTORY_DOWNLOADS, Environment.DIRECTORY_PICTURES, Environment.DIRECTORY_MOVIES, etc.

okay, then what if I don't want to expose the downloaded file and I am using, Environment.getDataDirectory() path for download? – Arc

For the question I had asked, you are correct that Android 10 accepts only known public directories. And for other folders like "data/data" we can use downloadRequest.setDestinationInExternalFilesDir(context, filePath, fileName) – Arc
