How to access Team Folders with Java API ?

Thank you for posting those samples amedeomantica

Because your Dropbox Team uses team space and member folders I'd like to make a suggestion. First, make sure you have the latest Java SDK (3.0.7).

Then add a call to get the current account information and root namespace:

FullAccount account = adminClient.users().getCurrentAccount();
String rootNS = account.getRootInfo().getRootNamespaceId();

Next, replace your call to listFolder() with this:

final ListFolderResult listFolderResult = dropBoxConnection.memberClient().withPathRoot(PathRoot.namespaceId(rootNS)).files().listFolder(path);

If there are issues with that, you can try varying the composition of your path string - try just using the literal string pathname vs the "ns:" format. Remember that all pathing will be relative to the root namespace (the Team root folder).

What the withPathRoot() method does is to "root" the chained API call at the given namespace. In your case, while you may have the proper namespace ID for the Team Folder, if you are not accessing it via the root namespace ID, it will not be visible to your user. This is because by default all calls without an explicit path root set are rooted in the home namespace (your user folder), not the team root where Team Folders live.

I suggest looking over "User's Home Folder & Team Root Folder" and the "Using a Namespace to Identify Content" in the Namespace Guide:

Hopefully, this gets you past the error.
