How to detect Dropbox folder is renamed. via Dropbox http-api or java-sdk

[Cross-linking for reference: https://stackoverflow.com/questions/54417566/how-to-detect-dropbox-folder-is-renamed-via-dropbox-http-api-or-java-sdk ]

If a file or folder is renamed, the new entry will have the same 'id' as the previous (non-deleted) entry.

So, if you want to keep track of renames, you should keep the existing state, from the previous /2/files/list_folder and /2/files/list_folder/continue calls.

Here's a more complete example:

curl -X POST https://api.dropboxapi.com/2/files/create_folder_v2 \

    --header "Content-Type: application/json" \

#   "metadata": {
#     "name": "test_325818",
#     "path_lower": "/test/test_325818",
#     "path_display": "/Test/test_325818",
#     "id": "id:25N5ksooX-sAAAAAAAM5zg"
#   }
# }

curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer <ACCESS_TOKEN>" \
    --header "Dropbox-API-Arg: {\"path\": \"/test/test_325818/test_325818.txt\"}" \

In this example, you can see how the folder originally at 
"/test/test_325818" was renamed to "/test/test_325818_renamed", but retained the same 'id' of "id:25N5ksooX-sAAAAAAAM5zg".

Thank You Greg.

It really works for me.
