I need to sync all the files from within a folder in Google Drive to a mobile app using the Google Drive API, and I do not see how to approach it.

some users of my android/java app have reported that they can’t upload a file to Google Drive.
The app uploads files to one specific Google Drive account.

I am trying to write a app script that add some custom properties to the file that stored in shared Drive. After trying multiple ways and reading through the documentationtext, I still can’t succeed adding or getting properties of a file.
Here is my coding for adding the AppProperties:

I have been working to a kotlin microservice that downloads file from GDrive.
To do that, I create oauth credentials and I have linked them to one user in our organization. I was able to access to files and folders contained into this user google drive. As soon as the folder was moved to a Shared Drive, I lost access from the microservice and I am not able to access a folder/file created by the same user in that shared drive.
What should I do to have access to a company shared folder from a microservice?
I also tried to share folders and file directly with the user that the microservice is supposed to “use” but nothing could fix the issue (a part creating a folder in the gdrive user’s home and share it into the shared structure with a “link”)
Thanks

I am using Google API to collect events (such as upload file/share).
I noticed in one log that a user got:
actor_is_collaborator_account: True.

My intention is to upload a file to a Google Drive and then retrieve the webViewLink of that file.
I do the following steps.

With the same code to upload file to google drive, linux and windows work well. but it does not work in aix.

I would like to mirror a public Google Drive to my laptop. What is the best way to do this? I have installed Google Drive for desktop and have been following instructions to go to Preferences, then Google Drive (folders from Drive) then Mirror files…how do I then specify the target public drive URL, (https//drive.google.com/drive/folders/1-JTOkg…Nj) that I want mirrorred locally for offline use?

I observe Google API service account getting a 404 when it tries to read a file (i.e. call the files.get method https://developers.google.com/drive/api/reference/rest/v3/files/get )

We are trying to integrate the Google Picker with an external system, and as part of the integration we want to prevent users from seeing documents which have come from the external system – the way that this is done elsewhere is by filtering based on a custom property, e.g. “EXTERNAL_SYSTEM_URI” which is embedded into any documents which have come from the system.
