Android Question ExternalStorage class GetParent

[yaniv hanya]

based on the ExternalStorage class from here

https://www.b4x.com/android/forum/t...access-sd-cards-and-usb-sticks.90238/#content

is there a way to get the parent folder from an ExternalFile?

Google documentation: https://developer.android.com/reference/android/support/v4/provider/DocumentFile

A single document may appear as the child of multiple directories, so it doesn't inherently know who its parent is. That is, documents don't have a strong notion of path. You can easily traverse a tree of documents from parent to child, but not from child to parent.

And see this: https://developer.android.com/refer...v4/provider/DocumentFile.html#getParentFile()

The external storage does include a "parent" feature that is based on the stack of folders. You can do something similar in your app.
If you are looking for a way to get the parent folder of the folder the user chose then it is not possible.

what I need to do is find the return path only to the directory that the user has chosen not beyond that.

There is no such thing. You only get a uri (stored in Root) and you can get the files and folders in that root folder.

The uri might include and might not include the actual path of the file system.
