android - GoogleAuthUtil: get access token that will provide an email address? -
i'm unable access token provide email address. i'm using googleauthutil. (the result says token invalid)
i use this:
mgoogleapiclient = new googleapiclient.builder (cordova.getactivity().getapplicationcontext()) .addconnectioncallbacks (this) .addonconnectionfailedlistener (this) .addapi (games.api) .addscope (games.scope_games) .addapi(plus.api) .addscope(plus.scope_plus_profile) .addscope(plus.scope_plus_login) .build ();
, this:
scope = "oauth2:" + scopes.profile + " " + "email";
dropping " email" works give me valid access token -- there's no email address in response.
here code.

it seems clearing app's permission in https://security.google.com/settings/security/permissions?hl=en trigger re-authorization screen, access token received .gettoken is stale. googleauthutil.cleartoken (context, accesstoken); needs used clear old token, or old token must time out. thus, can do:
accesstoken = googleauthutil.gettoken(context, accountname, scope); googleauthutil.cleartoken (context, accesstoken); accesstoken = googleauthutil.gettoken(context, accountname, scope); however:
it seems resolves after few iterations of re-launching app, because googleauthutil.gettoken asynchronous when new permissions required, , 2 separate permission screens pop up: 1 google (triggered googleauthutil.gettoken , 1 google+ (triggered googleapiclient.builder).
edit: using accountpicker class eliminates need use googleapiclient.builder!
