New Google Drive API, trashing files, folders and storing application data in app folder

Question

I am really glad that there was an update in the new Google Drive Android API recently, which finally added support for app folders and change listeners.
As I was testing this new API, I wanted to delete all files and folders in this app folder at one point.
I have found that the simplest way to do this will be to remove the app from Google Drive.
Unfortunately, when I opened app manager in Google Drive, i didn't find my app there.
I have found Google Documents, Forms, Drawings, Presentations and two Google Tables - probably the old and the new ones.
There are also two additional suspicious looking apps, one called simply Google Drive, the other one Project Default Service Account - both without an icon.

So my first question is "How can I put(add,show) my app there and then see it's content ?"

I have also recently found that there is no method to trash files or folders with this new Google Drive Android API, but it seems that it was there before and then was removed.

My second question is "Is there any option to trash files right now(probably not) with the new API only ?"

My third, last question is "How long will it take until a new update which will hopefully feature this option is released ?"

Answer 1

Most likely the "Project Default Service Account" is your app. Did you double check the app name and icon in the cloud console? I believe that is a default app name that is used if you don't set anything.

Answer 2

I don't understand the question #1 so I'll let others to elaborate.

Question #2: NO. Please see SO 22703040

Question #3: You will never know unless you are the Google developer yourself. Maybe not even then.
