getExternalStoragePublicDirectory deprecated in Android Q. How to save document file into public directory?

I want to get access to public directory files, for storing not: image, audio and video! I need to store: documents (for example: doc, pdf, bak, zip, etc...). I need these documents should stay on user device even after my app will be uninstalled. And I need user can access these document files from other apps.

In early versions of android, for documents folder, I can simply write down next line: 

File myDirectory = new File(Environment.getExternalStoragePublicDirectory(
        Environment.DIRECTORY_DOCUMENTS), "My documents");
if (!myDirectory.exists()) {
   if(myDirectory.mkdirs()){
      // directory exists, can place any files here                
   }
}

How can I do this in android Q? Or no way, and I just need to tell my users that my app doesnt support Android 10 at all?

p.s. I see this: getExternalStoragePublicDirectory deprecated in Android Q - No answer for my question

How can I do this in android Q?

Use ACTION_CREATE_DOCUMENT to allow the user to choose a location, and then store your content at the Uri that you get.

Or, use ACTION_OPEN_DOCUMENT_TREE to allow the user to choose a tree (e.g., directory). You can use the Uri that you get back with DocumentFile.fromTreeUri() to be able to create child documents. In each case, you wind up with a Uri that you can use to store the content.

Given a Uri, you can use ContentResolver and openOutputStream() to write the content to the location identified by the Uri.

This sample Java app (and its Kotlin counterpart) demonstrate how to work with files and content Uri values. I use ACTION_OPEN_DOCUMENT to allow the user to pick an existing text file or ACTION_CREATE_DOCUMENT to allow the user to create a new text file.
