android - GoogleAuthUtil:获取将提供电子邮件地址的访问 token 吗？

我无法获得访问 token 来提供电子邮件地址。我正在使用GoogleAuthUtil。 (结果表明 token 无效)

我用这个:

  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 ();

和这个:
scope = "oauth2:" + Scopes.PROFILE + " " + "email";
删除“电子邮件”可为我提供有效的访问 token -但响应中没有电子邮件地址。

这是我的代码。

最佳答案

似乎清除https://security.google.com/settings/security/permissions?hl=en中的应用程序许可确实会触发重新授权屏幕，但是从.getToken 接收到的访问 token 是过时的。需要使用GoogleAuthUtil.clearToken (context, accessToken);清除旧 token ，否则旧 token 必须超时。因此，我们可以这样做:

accessToken = GoogleAuthUtil.getToken(context, accountName, scope);
GoogleAuthUtil.clearToken (context, accessToken);
accessToken = GoogleAuthUtil.getToken(context, accountName, scope);

然而:

似乎只有重新启动应用程序几次迭代后才能解决，因为当需要新权限时GoogleAuthUtil.getToken是异步的，并且弹出两个SEPARATE权限屏幕:一个来自Google(从GoogleAuthUtil.getToken触发，一个从Google+(触发)来自GoogleApiClient.Builder)。

编辑:
使用AccountPicker类消除了使用GoogleApiClient.Builder的需要!
