GoogleAuthUtil：获取将提供电子邮件地址的访问令牌？

Question

我无法获取访问令牌来提供电子邮件地址。我正在使用 GoogleAuthUtil。 （结果说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 ();

还有这个：

scope = "oauth2:" + Scopes.PROFILE + " " + "email";

删除“电子邮件”可以为我提供有效的访问令牌——但响应中没有电子邮件地址。

这是我的代码。

似乎在https://security.google.com/settings/security/permissions?hl=en 中清除应用程序的权限确实会触发重新授权屏幕，但从 .getToken 收到的访问令牌已过时。需要使用GoogleAuthUtil.clearToken (context, accessToken);清除旧令牌，否则旧令牌必须超时。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);

但是：

这似乎只有在重新启动应用程序的几次迭代后才能解决，因为 GoogleAuthUtil.getToken 在需要新权限时是异步的，并且会弹出两个单独的权限屏幕：一个来自 Google（从 GoogleAuthUtil.getToken 和一个来自 Google+（由GoogleApiClient.Builder 触发）。

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