I have been googling for some days already how apps can download a file directly to Download directory on Android 10 (Q) without having to ask user where to place it, the same way Chrome does. But then I analyzed Chrome and it targets Android 10 without using requestLegacyExternalStorage. I first analyzed Whatsapp to see how they achieve it but they make use of requestLegacyExternalStorage attribute on AndroidManifest.

Impossible? but then why Google Chrome or other browsers are able to do that? They in fact still download files to Download directory without asking user in Android 10. In Android 9 or lower I directly download those files to Download directory, but that's now impossible in Android 10 without showing an Intent to the user to ask where to download them.

Lets say I'm developing a chat app that is able to share with others ANY kind of files (no mimetype restriction): like images, videos, documents, but also compressed files like zip, rar, apk or even less frequent types of files like photoshop or autocad files, for example.
