dbxClient.files().listFolder("") only returns 1 folder

I want to list all the files under my member ID. I use the following code and it only show 1 folder even though I have 8 folders starting from root.

 

DbxClientV2 dbxClient = dbxTeamClient.asMember(teamMemberId);
ListFolderResult fileRes = dbxClient.files().listFolder("");
List<Metadata> folders = fileRes.getEntries();
String metaDataCursor = fileRes.getCursor();

while (true)
{
    for (Metadata metadata : folders)
    {
        String type;
        String details;
        if (metadata instanceof FileMetadata)
        {
            FileMetadata fileMetadata = (FileMetadata) metadata;
            type = "file";
            details = "(rev=" + fileMetadata.getRev() + ")";
        }
        else if (metadata instanceof FolderMetadata)
        {
            FolderMetadata folderMetadata = (FolderMetadata) metadata;
            type = "folder";
            details = folderMetadata.getSharingInfo() != null ? "(shared)" : "";
        }
        else if (metadata instanceof DeletedMetadata)
        {
            type = "deleted";
            details = "";
        }
        else
        {
            throw new IllegalStateException("Unrecognized metadata type: " + metadata.getClass());
        }

        System.out.printf("\t%10s %24s \"%s\"\n", type, details, metadata.getPathLower());
    }

    if (!fileRes.getHasMore())
    {
        break;
    }
    // update cursor to fetch remaining results
   fileRes = dbxClient.files().listFolderContinue(metaDataCursor);
   folders = fileRes.getEntries();
   metaDataCursor = fileRes.getCursor();
}

I then changed my code as the following then it shows the first folder and all the folder and files from that branch but the left 7 folder are not show at all. Any suggestiong to fix it?
TThank you.

DbxClientV2 dbxClient = dbxTeamClient.asMember(teamMemberId);
ListFolderBuilder builder = dbxClient.files().listFolderBuilder("");
builder.withRecursive(true);
ListFolderResult fileRes = builder.start();
