Originally this service was designed to allow applications to request auth tokens for Google APIs using the proprietary ClientLogin mechanism. However, this service has been updated to support getting OAuth 2.0 access tokens for Google APIs.
In order to get an OAuth 2.0 access token, you simply need to call
AccountManager.getAuthToken() to
request a token using an authTokenType of oauth2:<scope>. For example, to request
access to the Google Tasks API, specify an authTokenType of oauth2:https://www.googleapis.com/auth/tasks.
