5.How does extension work?
Get Access to App Data Folder of User's drive
First of all to access a google service we need credentials from google (will be discussed next) and consent from user.
This is how we get consent from user:
Since all the authentication happens by Google Sign In activities so app/extension will be able to access data which was granted by user.
Scopes Requested
The extension works with App Data Folder so the only requested scope is DriveScopes.DRIVE_APPDATA.
It does not allow any app/service to read/write files outside of the folder assigned to it by Drive.
However, there is no any other limit so app can do whatever it wants with that specific space.
Create OAuth Client for your app
To get Google verify your app to use Drive you need to register your app in Google Console, for which steps are given here: GitHub - mesadhan/google-drive-app: Google Drive API with Android
Is it safe?
Yes, app/extension will not request for any sensitive data.
It gets following information, on the consent of user:
- display name
- photo url
These are usually public for a Google Account
