There's a nice feature on google drive that allows an application to store data not visible for users.
https://developers.google.com/drive/appdata
Is it possible to share this application data between users, just like other google drive files?

You can't share appdata files within the Drive's existing permissions model. Appdata content is supposed to be exclusive to the application. If you try to change permissions for an appdata file, you'll receive a 403 with the following error message:
Method not supported for appdata contents

I am building an app using Google Drive API and store data in the user's appdata space in the user's Google Drive. This way we can store data to avoid user accidentally delete since it's hidden from the user's view https://developers.google.com/drive/api/guides/appdata
Question: can other apps (maybe even hacker) using the same API and pretend to be our app to fetch the our app data?
If you check the documentation found on Store application-specific data . You will find it states.
This folder is only accessible by your application and its contents are hidden from the user and from other Drive apps.
Only your app or rather your client id can access the files that it created.
Google recently announced that to access certain files on google drive my application should use a resouceKey along with the fileId when trying to access google drive through Api. When I checked the files in my google drive I find that not all files have the new resourceKey. I uploaded a new file and that too does not have the new resourceKey.
This lead me to wonder as to what criteria should a file satisfy to be requiring the new resourceKey?
Basically, the resourceKey is required for users who have not been shared the file specifically with them (that is, files shared with Anyone with the link or Anyone in the domain, but not shared with that user specifically) and which haven't accessed that file previously.
Because of this, files that you own, files that you have accessed before, and files that have been shared with you specifically don't require a resourceKey.
You can check the details of the impacted files on the alert center.

Access link-shared files using resource keys
I am building an app that functions as a markdown editor, and have Google authentication / login functioning. I have users asking if they can choose to have their documents save to their google drive rather than to my servers, which seems to work fine via the Google Drive v3 API, saved to the app data folder.
However, users are also able to generate a collaborator link for others to visit and which allows them to edit the files as co-owners. I would like to maintain this sharing capability with the Google Drive files, but this (very old) answer suggests that sharing in this way may not possible with files in appdata, because:
Appdata content is supposed to be exclusive to the application.
Does this mean that, as long as my users all access these files exclusively via the app, sharing appdata between users is possible? Or is the appdata folder exclusive to the application and the user? If so, is it at least possible to share editor access to google drive files created by my app but outside the appdata folder?
I'm imagining this process:
User1 creates a file in my app and then my app saves it to his Google Drive (preferably in appdata)
User1 generates a collaborator link via my app, gives it to User2
User2 visits the link which opens User1's file within my app, edits it
User2's edits are saved, and my app updates the original User1's file via the API
Question:
"Or is the appdata folder exclusive to the application and the user?"
Answer:
Yes, it is exclusive for your app on their Drive.
Notes:
Use the AppData folder for Application Data, not User Data.
If the file is created by your app, and you want to store it in the user's Drive, you can use the https://www.googleapis.com/auth/drive.file scope. You app will always have access to that file because it was created by it.
Keep in mind that if your app requires restricted scopes you will have to go through verification.
Can i share the files which are uploaded in the Application Folder with other Google account users ?
https://developers.google.com/drive/android/appfolder
I want the user uploading the file to maintain an Access Control List.
If Appdata does not support it, is there any other alternative provided by google for it?
I am using Google Drive API in order to access the documents of a user from their drive. Following the instructions here https://developers.google.com/drive/v2/reference/files/list
Using the scope https://www.googleapis.com/auth/drive at the time of authentication.
Users are authorizing Google app of our system to access their documents but the problem is that they not getting all documents from their drive when they are trying to access the documents from their drive in our system. (Though they are getting a few documents from their drive). Any help ?
We need to see the specific call to /files/list.
Some things to check ...
Are the missing files owned by the user?
Is there a nextPage in the response that you are not following?
Is there a query in your /files/list?
