Android Question external storage - direct access to USB-device

[fransvlaarhoven]

Hello,

in Your example You are using the following code to pick a folder:

Dim i As Intent
i.Initialize("android.intent.action.OPEN_DOCUMENT_TREE", "")
i.PutExtra("android.content.extra.SHOW_ADVANCED", True)
StartActivityForResult(i)

Is it possible to pick only the attached usb-stick and not allowing the user to select the sd-card?

It is not possible to limit it.

Starting from Android 8 you can set the initial path, though it will not limit the user from choosing a different one.

I might have asked the wrong question:

what I try to have is a system where the user can only read/write files to the attached USB-stick and has no access at all to the sd-card, internal storage.

From what i can see when running your code, picking a folder returns something like:

Native=(TreeDocumentFile) android.support.v4.provider.TreeDocumentFile@3f0ebee

Is there a standard way to point directly to the attached USB-stick?

The only way to get access to external storages is by asking the user to choose it in the picker.

Once the user chose it you can store the uri and reuse it.
