My Android app creating a file on Google Drive using new Google Drive API. I'm getting DriveFile object successfully.
The question is: how to share this file from my app? Links to relevant topics and especially code samples are appreciated.
The Android-specific API does not yet support sharing. You can use the RESTful web API to do this. See permissions.
From a DriveId you can get the resourceId, which is the id you need in order to access a file in the web API.
