It seems as though all the current AuzthzModules use an http based
approach to requesting an Oauth2 token. I see this being done in
OAuth2WebFragmentFetchAutorization#doAuthorization method, where
an OAuthWebViewDialog is used to trigger the Oauth2 token request.<br>
<br>
To use Google Play services to trigger an Oauth2 token request, we
won't use an http approach, but rather we start an activity to
select an account and request an Oauth2 token. Once the token is
retrieved it can then be used with the standard http Oauth2 API.<br>
<br>
(One caveat: the google play services token response doesn't
provide a refresh token. I believe this to be a non-issue as the
token request process is trivial when using google play services
(no authentication step)).<br>
<br>
I see to ways to implement this feature:<br>
<br>
1) Generalize the OAuth2WebFragmentFetchAutorization into an
interface, and have one implementation to handle http-based token
requests, and second implementation to handle intent-based token
requests.<br>
<br>
2) Add a OAuth2AuthorizationConfiguration option to use intents
instead of http, and trigger a different workflow within the
OAuth2WebFragmentFetchAutorization#doAuthorization method if that
config is set.<br>
<br>
My preference is for 2) because it's a) simpler, and b) it is
really only during the #doAuthorization method that we have a
different approach.<br>
<br>
Thoughts? I'll start with implementing approach (2) unless I hear
otherwise.<br>

<br>
I recently wrote a Cordova plugin that retrieves
a Oauth2 token on<br>
Android using Google Play Services. The
advantage of this approach is<br>
it leverages the single-sign-on capabilities of
android, and the app can<br>
retrieve the Oauth2 token without requiring
Authentication from the<br>
user. I blogged about it here:<br>
<br>

target="_blank">http://www.bleathem.ca/blog/2015/02/cordova-oauth-google-services.html</a><br>
<br>
Using a promise-based API it's fairly trivial to
fallback to a<br>
traditional Web authentication/authorisation for
the Oauth2 token when<br>
the google-play-services approach isn't
supported.<br>
<br>
I'm aware the aerogear team has a Oauth2 cordova
plugin [1], but it's<br>
not clear to me if the google-play-services
integration is supported.<br>
If the Aerogeam would find it useful, I'd be
more than happy to provide<br>
a PR to the aerogear cordova plugin providing
such integration.<br>
<br>
Thoughts?<br>
