Android应用使用Firebase GitHub登录失败求助

问题描述 #

我在Android应用中基于Firebase实现GitHub登录功能，目前每次尝试登录都会失败，但没有任何报错日志输出。该功能此前完全正常，且我没有对代码或配置做任何改动，就突然出现了这个问题。同时，Twitter登录也出现了完全相同的失效情况，我怀疑是Firebase的OAuth登录提供商功能出现异常。

已完成的配置 #

• 在Firebase控制台中正确配置了应用的SHA1值，启用了GitHub登录提供商，并填写了对应的Client ID与Secret
• Twitter登录的对应配置也已完成（同样出现登录失败问题）

public void onClickGitHubButtonLogIn(String name) {
    provider = OAuthProvider.newBuilder("github.com");
    // Target specific email with login hint.
    provider.addCustomParameter("login", name);
    // Request read access to a user's email addresses.

    List<String> scopes =
            new ArrayList<String>() {
                {
                    add("user:email");
                }
            };
    provider.setScopes(scopes);

    Task<AuthResult> pendingResultTask = mAuth.getPendingAuthResult();
    if (pendingResultTask != null) {

        // There's something already here! Finish the sign-in for your user.
        pendingResultTask
                .addOnSuccessListener(
                        new OnSuccessListener<AuthResult>() {
                            @Override
                            public void onSuccess(AuthResult authResult) {
                                openMainPageActivity();
