Хранение данных для входа в android facebook для разбора

Question

Может кто-нибудь помочь мне, как хранить профиль пользователя facebook для анализа библиотеки? Я делаю приложение для Android. Я хочу, чтобы после входа в систему с помощью facebook пользовательская информация (например, электронная почта, имя, пол) хранила для анализа библиотеки, а затем приложение показывало новую активность. Но мое приложение застряло в регистрации в диалоговом окне после аутентификации в facebook и ничего не хранило для анализа библиотеки. Кто-нибудь может мне помочь? Thankyou очень

Answer 1

Я нахожусь в одной лодке, я новичок, который использует синтаксический анализ, и это работает для меня.

//Make sure that a session is opened and that you asked for the required permission 

if(ParseFacebookUtils.getSession().isOpened()) 
{ 

Request.newMeRequest(ParseFacebookUtils.getSession(), new Request.GraphUserCallback() 
{ 
@Override 
public void onCompleted(GraphUser user, Response response) 
{ 
if (user != null) 
{ 
String Name = user.getName; 
String email = user.getEmail; 
//Use the get Method to get the info from facebook 

//Then save it to the parse DB 
ParseObject post = new ParseObject("post");  
    post.put("name", Name); 
     post.saveInBackground();       
} 
    } 
    }).executeAsync(); 
    }

My LoginFragment выглядит так и сохраняет имя пользователя Facebook для совместного использования d предпочтений.
