检索用户性别虽然Google使用Firebase登录但未获得所有用户性别？

Question

场景:

我想在我的Android应用程序中GOOGLE SIGN IN使用登录Firebase Google Login,我的基本需求是在我的应用程序中登录时检索USER性别USER.

问题:

即使我得到的性别USERS,但不是全部 USERS,那么,是因为越来越问题只是一些用户的性别是很奇怪的,所以我的问题是,为什么我没有得到所有用户的性别,同时登录？

public void performFirebaseLogin(GoogleSignInAccount acct, final Context context, final LoginSPrefRepositoryImpl loginSPrefRepositoryImpl) {
        AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
        final GoogleAccountCredential googleCredential = GoogleAccountCredential.usingOAuth2(
                    context, Collections.singleton(Scopes.PROFILE));
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener((Activity) context, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {

                            FirebaseUser user = mAuth.getCurrentUser();
                            if (user != null) {
                            //here i am calling profile detail of user
                                new GetProfileDetails(user, googleCredential,loginSPrefRepositoryImpl).execute();
                            } else {
                                    onLoginListener.onFailure("Login Failed");
                            }

                            // If sign in fails, display a message to the user.

问题是gender用户应该在他的Google +帐户上明确共享。我建议你自己尝试一下。

1. 转到此页面https://developers.google.com/people/api/rest/v1/people/get
2. 类型resourceName=people/me和personFields=genders
3. 执行请求，很可能您会得到仅包含resourceName和etag字段的响应。
4. 现在转到https://plus.google.com/u/0/me页面，这将打开您的 G+ 页面并打开帐户设置。或者您可以直接打开https://aboutme.google.com/u/0/页面。
5. 单击您的性别旁边的图标。这是可见性设置，因此用户可以选择是否要将自己的性别公开、私有或仅与圈子分享。我建议您尝试不同的可见性选项，并在第 3 步检查它如何改变响应。

TL;DR：G+ 上有Gender可见性设置，用户可能选择不分享他的性别，并且在身份验证期间没有专门的配置文件范围可供请求。此设置完全私密。
