Google Drive API through Google App Engine

Question

I\'m trying to use the Google Drive API through the App Identity interface provided with Google App Engine. This basically allows my web application to communicate with Goog

Answer 1

What I read here (Google drive via service accounts) was that you use a slightly different style that uses an API KEY that you retrieve from the Developer Console.
The pertinent parts for me were to generate a "Key for Server Applications", then use this technique, which I hadn't read anywhere else!

      HttpTransport httpTransport = new NetHttpTransport();
  JsonFactory jsonFactory = new JacksonFactory();
  AppIdentityCredential credential =
      new AppIdentityCredential.Builder(DriveScopes.DRIVE).build();
  // API_KEY is from the Google Console as a server API key
  GoogleClientRequestInitializer keyInitializer =
      new CommonGoogleClientRequestInitializer(API_KEY);
  Drive service = new Drive.Builder(httpTransport, jsonFactory, null)
      .setHttpRequestInitializer(credential)
      .setGoogleClientRequestInitializer(keyInitializer)
      .build();
