How to get list of all folders and files from google drive in android

Question

I have started developing a app in which i have to list of all folders and files from google drive.

I have go through all the documentation and below demo links as suggested in this stack overflow answer ,

https://github.com/googledrive/android-demos

And

https://github.com/seanpjanson/RESTDemo

I have make these both demo working properly. But I am not able to list out all the folders and files of google drive. Currently i can only list out those files which are created by app only . If there is any other folder created from web then it is not showing in the log or list.

Can any one help me on this. Any link, suggestion , guidance will be helpful.

I am having a doubt that may be this is not allowed but there is a sample app which is BubbleUPnP in this app they have listed the folders and files. How can i achieve this in my app ?

Any help will be appreciated.

You need to request the correct Scope.

To have full access to all files\\folders requires the scope: https://www.googleapis.com/auth/drive
