Android Question ExternalStorage - Rename a folder.

[AndreyPozdnyakov]

After selecting a folder - is it possible to rename it?
If this is not possible, then how can I rename a folder in an arbitrary location?

Is it possible to use PersistantUri for this?

No guarantees but try this, where AnExternalFile is an ExternalFile returned by FindFile. Result is True if it succeeds

Dim NewName as String = "NewName"
Dim result as Boolean
Result = AnExternalFile.Native.RunMethod("renameTo", Array(NewName))

Comments for renameTo from the Android API reference for DocumentFile which is what the Native member of ExternalFile is

Renames this file to displayName.

Note that this method does not throw IOException on failure. Callers must check the return value.

Some providers may need to create a new document to reflect the rename, potentially with a different MIME type, so getUri and getType may change to reflect the rename.

When renaming a directory, children previously enumerated through listFiles may no longer be valid.

Thank you very much, I will try to do it.
