Updated  getExternalStoragePublicDirectory   is deprecated   To get the download folder from a Fragment    val downloadFolder   requireContext   getExternalFilesDir Environment DIRECTORY DOWNLOADS    From an Activity   val downloadFolder   getExternalFilesDir Environment DIRECTORY DOWNLOADS    downloadFolder listFiles   will list the Files   downloadFolder  path will give you the String path of the download folder

If you are using Marshmallow  you have to either    Request permissions at runtime  the user will get to allow or deny the request  or  The user must go into Settings -  Apps -   Your App  -  Permissions and  grant storage access    This is because in Marshmallow  Google completely revamped how permissions work

If you re using a shell  the filepath to the Download  no  s   folder is   storage emulated 0 Download

You should add next permission    lt uses-permission android name  android permission WRITE EXTERNAL STORAGE    gt    And then here is usages in code   val externalFilesDir   context getExternalFilesDir DIRECTORY DOWNLOADS

For your first question try   Environment getExternalStoragePublicDirectory Environment DIRECTORY DOWNLOADS       available since API 8   To access individual files in this directory use either File list   or File listFiles    Seems that reporting download progress is only possible in notification  see here
