火力地堡和新的谷歌登录在Android上 [英] Firebase and new Google Sign-In on Android

问题描述

我想添加支持href="https://developers.google.com/identity/sign-in/android/" rel="nofollow">新的谷歌登录公布为播放业务8.3.0部分。 我成功地配置了项目，我越来越从GoogleApiClient令牌，但火力地堡是返回一个  无效证书错误  当调用 ref.authWithOAuthToken（谷歌，令牌）

I'm trying to add support for the new Google Sign-in announced as part of Play services 8.3.0. I successfully configured the project and I'm getting a token from the GoogleApiClient, but Firebase is returning an Invalid Credentials error when calling ref.authWithOAuthToken("google", token)

Google+登录功能的工作，但需要开发棉花糖时，这是一个痛苦的单独许可。 火力地堡的android教程拥有的Google+签到样品和我的感觉是他们不'有新的谷歌支持登录在还。

Google+ sign-in is working but that requires a separate permission which is a pain when developing for Marshmallow. Firebase android tutorial has a Google+ sign-in sample and my feeling is that they dont' have support for the new Google Sign-In yet.

有没有人尝试新的谷歌登录在与火力地堡连接，并得到它的工作？

Has anyone tried the new Google Sign-In in connection with Firebase and got it to work?

推荐答案

这是的步骤组合添加登录到Android的和授权与谷歌进行的REST API 。

一旦你有一个 GoogleSignInResult 你可以从该帐户名称，然后请求令牌最小范围：

Once you have a GoogleSignInResult you can get the account name from that and then request the token with the minimal scopes:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        GoogleSignInAccount acct = result.getSignInAccount();

        String email = acct.getEmail();

        // TODO: run an async task to get an OAuth2 token for the account
    }
}

异步任务将需要请求这些示波器：

The async task will need to request these scopes:

protected String doInBackground(String... params) {
    String scopes = "oauth2:profile email";
    String token = GoogleAuthUtil.getToken(getApplicationContext(), email, scopes);
    // exception handling removed for brevity
    return token;
}

现在，您可以使用该令牌登录到火力地堡像往常一样：

Now you can use the token to sign in to Firebase as usual:

ref.authWithOAuthToken("google", token, new Firebase.AuthResultHandler() {...
