如何在Android中更新来自Firebase的电子邮件？

Question

我正在使用此代码:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

user.updateEmail("user@example.com")
        .addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if (task.isSuccessful()) {
                    Log.d(TAG, "User email address updated.");
                }
            }
        });

但我仍然无法更新登录用户的用户电子邮件ID.其他工作正常但不是这个.

您需要重新验证您的用户.根据文档,更改主电子邮件地址是一项敏感操作.

重新认证:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
        // Get auth credentials from the user for re-authentication
        AuthCredential credential = EmailAuthProvider
                .getCredential("user@example.com", "password1234"); // Current Login Credentials \\
        // Prompt the user to re-provide their sign-in credentials
        user.reauthenticate(credential)
                .addOnCompleteListener(new OnCompleteListener<Void>() {
                    @Override
                    public void onComplete(@NonNull Task<Void> task) {
                        Log.d(TAG, "User re-authenticated.");
                        //Now change your email address \\
                        //----------------Code for Changing Email Address----------\\
                        FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
                        user.updateEmail("user@example.com")
                                .addOnCompleteListener(new OnCompleteListener<Void>() {
                                    @Override
                                    public void onComplete(@NonNull Task<Void> task) {
                                        if (task.isSuccessful()) {
                                            Log.d(TAG, "User email address updated.");
                                        }
                                    }
                                });
                        //----------------------------------------------------------\\
                    }
                });
