title: Android Google Drive App data folder not listing all childrens
body: <p>I have used the new Google Play services 4.3 to back-up my app data to the "App Folder" from Google Drive.
  I followed the instructions from this link <a href="https://developers.google.com/drive/android/appfolder" rel="noreferrer">Storing Application Data</a>. I checked in "Manage Apps" and the file seems to be added. If I try to list the children of the App Folder, they are returned successfully.</p>
  
  <p>The issue appears when I install the app on another device (properly synced), or if I uninstall and install the app again on the same device. When I tried to list the children of the App Folder, the count returned is 0.</p>
  
  <p>PS: I tried querying with both:</p>
  
  <pre><code>Drive.DriveApi.getAppFolder(mGoogleApiClient).listChildren(mGoogleApiClient)
  </code></pre>
  
  <p>and </p>
  
  <pre><code>Drive.DriveApi.getAppFolder(mGoogleApiClient).queryChildren(mGoogleApiClient, query)
  </code></pre>
