Enumerating folders and files using Google Drive SDK V2

I am a little confused by the v2 Google Drive SDK.

There seems to be 2 methods to retrieve information about files and folders.

files.list and children.list

Using files.list I do not seem to be able to narrow my search to files in a specific folder but using children.list only returns very basic file information such as ID. There are no filenames.

It looks like I have to retrieve a list of children and then perform a request for each child to find out its filename which seems very inefficient.

What is the normal\correct way to enumerate folders and their contents using Google Drive?

If you want to get all the folders in your drive use :

FileList folders=service.files().list().setQ("mimeType='application/vnd.google-apps.folder'").execute();
for(File fl: folders.getItems()){
     Log.v(TAG+" fOLDER name:",fl.getTitle());
}

Alternative approach is to use files.list with a query expression to limit by parent.

q='id-of-parent' in parents

This will give you the same results as the child collection, but with the full metadata for each item.

Update --

This can now be achieved with files.list. You can pass the q parameter with a query testing the parents of a file or folder.

q='MYFOLDERID' in parents

More search parameters and options and examples here: https://developers.google.com/drive/search-parameters

Original answer --

Yes, this is correct. We are looking to improve this feature, but unfortunately you are stuck with this for now - sorry.

If you are enumarating all the files and folders, a better solution might be to get a flat list, and use the parents array in a file to generate the hierarchy.

+1 returning metadata (at least filename) for children.list
