Android Q - How to get real path of Downloads folder

Question

With Intent.ACTION_OPEN_DOCUMENT_TREE I get this uri :

content://com.android.providers.downloads.documents/tree/downloads

How can I convert it to /storage/emulated/0/Download - the real path? I don't want use

Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)

because is deprecated.

EDIT : I need real path of public location for downloads, because on android Q, this is the folder where should be stored public documents.

try getExternalFilesDir(), getExternalCacheDir(), or getExternalMediaDir() (methods on Context) instead of Environment.getExternalStorageDirectory(). — Jawad Malik, Oct 08 '19 at 08:42
thank you, all these methods returns real paths, but from private folder, not from public location, I updated my question. — user1063364, Oct 08 '19 at 08:45
`location for downloads, because on android Q, this is the folder where should be stored public documents.` Well there is a Documents directory for that i think. — blackapps, Oct 08 '19 at 09:07
`I need real path` No. Not at all. Use the uri itself to create files in it. You should forget about File and FileInputStream. — blackapps, Oct 08 '19 at 09:09
old games don't understand uris, i must convert between uris and real paths :( I get file descriptor from resolver.openFileDescriptor everywhere where I could replace it. Maybe I should ask "how to convert real path to uri" — user1063364, Oct 08 '19 at 09:13
WIth getContentResolver(),openFileDescripter() you dont use a 'real path' but an obtained file uri. — blackapps, Oct 08 '19 at 09:16

Based on the docs, use DCIM/... for the RELATIVE_PATH, where ... is whatever your custom subdirectory would be. So, you would wind up with something like this:

  val resolver = context.contentResolver
  val contentValues = ContentValues().apply {
    put(MediaStore.MediaColumns.DISPLAY_NAME, "CuteKitten001")
    put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg")
    put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/PerracoLabs")
  }

  val uri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)

  resolver.openOutputStream(uri).use {
    // TODO something with the stream
  }

Note that since RELATIVE_PATH is new to API Level 29, you would need to use this approach on newer devices and use getExternalStoragePublicDirectory() on older ones.

Maybe I don't understand your answer, but I don't see how to get real path of Downloads (what is on Android Q folder where should I store public documents) from Uri. – user1063364 Oct 08 '19 at 08:30
Follow this link to find Real_Path: https://developer.android.com/reference/android/provider/MediaStore.MediaColumns#RELATIVE_PATH – Shahzad Ali Oct 08 '19 at 10:51
Unfortunately, it does not work. resolver.query(uri, new String[]{MediaStore.MediaColumns.DISPLAY_NAME, MediaStore.MediaColumns.RELATIVE_PATH}, null, null, null); returns null for second field, first returns correctly display name. Maybe it works only for files, not for folders :( Tested on Q emulator – user1063364 Oct 09 '19 at 11:02
This answer didn't in any way answer the question at all. – yams May 18 '20 at 19:11
