Facebook登录使用Parse始终返回user.isNew（）假的Andr​​oid [英] Facebook login with Parse always returns false in user.isNew() Android

问题描述

我用解析Android中的Facebook登录的问题。
一切工作正常，但我总是得到用户通过Facebook登录。

我发现了同样的问题，一个人在这里<一个href=\"https://stackoverflow.com/questions/25334873/facebook-login-not-working-properly-parse\">Facebook登录工作不正常（解析）但对我来说他的回答不工作。

 列表＆LT;串GT;权限= Arrays.asList（电子邮件）;
        ParseFacebookUtils.logIn（权限，getActivity（），新LogInCallback（）{
            @覆盖
            公共无效完成（ParseUser用户，ParseException的错误）{                如果（用户== NULL）{
                    Log.d（WelcomeMainFragment
                            嗯哦用户取消了Facebook登录）;                }否则如果（user.isNew（））{
                    Log.d（WelcomeMainFragment
                            用户注册了，并通过Facebook登录！）;
                }其他{
                    Log.d（WelcomeMainFragment
                            用户登录通过Facebook！）;
                }
            }
        }）;
 

user.isNew（）总是返回假的！即使在我的应用程序的新Facebook的帐户。
我需要有工作是否新款（）方法，能在code的该块创建解析用户的第一次。

非常感谢。

解决方案

经过一番研究，我发现了什么问题。
基本上，我有两个问题：

1. 我没有得到正确的密钥散列。

  

密钥工具-exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore
  YOUR_RELEASE_KEY_PATH | OpenSSL的SHA1 -binary | OpenSSL的BASE64

做上述我得到了错误的密钥散列。所以，我鼓励你这块code，以获得它：

  {尝试
    PackageInfo信息= getPackageManager（）。getPackageInfo（
            your.package.name
            PackageManager.GET_SIGNATURES）;
    对（签字签名：info.signatures）{
        消息摘要MD = MessageDigest.getInstance（SHA）;
        md.update（signature.toByteArray（））;
        Log.d（KeyHash：Base64.en codeToString（md.digest（），Base64.DEFAULT））;
        }
}赶上（ē的NameNotFoundException）{
}赶上（抛出：NoSuchAlgorithmException E）{
}
 

您在调试和生产执行它得到这两个键。

<醇开始=2>

最重要的问题是，我不得不允许解析Facebook的身份验证和包括Facebook应用程序ID和应用程序的秘密。你可以做，去设置>身份验证>的Facebook。

我希望可以帮助别人。

I have an issue with Facebook login in Android using Parse. Everything is working fine but I always get User logged in through Facebook.

I found a guy with the same problem here Facebook Login not working properly (Parse) but his answer doesnt work for me.

        List<String> permissions = Arrays.asList("email");
        ParseFacebookUtils.logIn(permissions, getActivity(), new LogInCallback() {
            @Override
            public void done(ParseUser user, ParseException err) {

                if (user == null) {
                    Log.d("WelcomeMainFragment",
                            "Uh oh. The user cancelled the Facebook login.");

                } else if (user.isNew()) {
                    Log.d("WelcomeMainFragment",
                            "User signed up and logged in through Facebook!");


                } else {
                    Log.d("WelcomeMainFragment",
                            "User logged in through Facebook!");
                }
            }
        });

user.isNew() always returns false! even with new facebooks accounts in my app. I need to have working isNew() method to be able to create parse users for first time in that block of code.

Thanks a lot.

解决方案

After some research I found what the problem was. Basically I had two problems:

1. I wasn't getting the key hash properly.

keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64

Doing above I was getting the wrong key hash. So I encourage you to get it with this piece of code:

try {
    PackageInfo info = getPackageManager().getPackageInfo(
            "your.package.name", 
            PackageManager.GET_SIGNATURES);
    for (Signature signature : info.signatures) {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        Log.d("KeyHash:", Base64.encodeToString(md.digest(), Base64.DEFAULT));
        }
} catch (NameNotFoundException e) {
} catch (NoSuchAlgorithmException e) {
}

You have to execute it in debug and production to get both keys.

2. The most important problem was that I had to allow Facebook authentication on Parse and include the Facebook app id and app secret. You can do that going to Settings > Authentication > Facebook.

I hope that can help someone.
