title: Android Google Drive Api share files across devices and accounts
body: <p>I'am using the <strong>Google Drive Android API</strong>. My application is synchronizing files to a google drive folder. This is working properly.<br>
  Additionally, I want to share those folders and files with other users. Unfortunately from another device and account in the same app I can only access files/folders which I have picked through the Files/Folder pickers (see <a href="https://github.com/googledrive/android-demos/tree/master/app/src/main/java/com/google/android/gms/drive/sample/demo" rel="nofollow noreferrer">https://github.com/googledrive/android-demos/tree/master/app/src/main/java/com/google/android/gms/drive/sample/demo</a>) </p>
  
  <p>My GoogleApiClient is getting the scope: <code>Drive.SCOPE_FILE</code>. So description says: </p>
  
  <blockquote>
    <p>Per-file access to files created or opened by the app</p>
  </blockquote>
  
  <p>Since I am using the same app on another device with a different account shouldn't I be able to access those files? Btw with the same account on another device this is working.</p>
  
  <p>Is there any other solution? I've already checked the REST API but I am afraid this would make the whole code much more complex.</p>
