我不能够捕捉到断点回调方法。如果你经历了这个错误，请帮助。

下面

是我获取用户详细信息代码：

private void onSessionStateChange(Session session, SessionState state, Exception exception) { 
    //RFR//_("onSessionStateChange----------------"); 
    /////////////// super.onSessionStateChange(state, exception); 
    if (state.isOpened()) { 
     readUserInfo(session); 
    } else if (state.isClosed()) { 
     // Session closed 
    } 
} 

private Request.GraphUserCallback graphCallback = new Request.GraphUserCallback() { 

     // callback after Graph API response with user object 
     @Override 
     public void onCompleted(GraphUser user, Response response) { 
      String name = user.getName(); 
      String gender = (String) user.getProperty("gender"); 
      String email = (String) user.getProperty("email"); 
      String birthday = user.getBirthday(); 
      Log.d("FB----->","name: "+ name +" gender: "+ gender +" email: "+ email +" birthday: " +birthday); 

     } 

}; 

    public void readUserInfo(Session session){ 
     // make request to the /me API 
     Request.executeMeRequestAsync(session, graphCallback); 
    }

及以下，我已经设置权限：

openRequest.setPermissions(Arrays.asList("user_birthday", "email", "user_location"));

下面是我从图形API得到的回应，当从浏览器中检查：

{ 
    "id": "1000000XXXXX930", 
    "name": "First Last", 
    "first_name": "First", 
    "last_name": "Last", 
    "link": "http://www.facebook.com/<myusername>", 
    "username": "<myusername>", 
    "gender": "male", 
    "locale": "en_US" 
}

我有这样一个使用FacebookSDK 4.0 asimilar问题。你已经解决了吗？ – stackex

你给“电子邮件”权限请求Facebook应用程序访问任何用户的电子邮件ID？

如果您想使用api访问Facebook用户的电子邮件ID，那么您必须给予电子邮件许可。有关用户个人资料的一般信息不会为您提供Facebook用户的电子邮件地址。

Email Permissions in Facebook API

注：一些用户也把安全性不共享电子邮件地址，任何其他然后也可能是情况下，你不会得到的电子邮件地址。

希望它能帮助你。

是的，我正在使用我的帐户进行测试，并检查了fb上的许可，它们已正确设置。但是我没有把这些细节公诸于众。可能是这个问题？ – Ankit

首先通过记录来检查响应，并检查它是否包含任何电子邮件字段？ –

我已经打印了要记录的详细信息，请参阅代码中的onCompleted。但是我不明白它在logcat上。 – Ankit

您确实需要获取某人的电子邮件的权限，虽然有些人有他们的隐私设置，以便您可以在未获得此许可的情况下获得他们的电子邮件，但大多数人不会。

我已设置权限。请参阅问题的下半部分。 – Ankit

的代码这件作品是在获得所需的权限工作的罚款与我这也将帮助您获得电子邮件许可

是否与你合作？ –

你必须检查是这样的：

private Request.GraphUserCallback graphCallback = new Request.GraphUserCallback() { 

    // callback after Graph API response with user object 
    @Override 
    public void onCompleted(GraphUser user, Response response) { 
     String name = user.getName(); 
     String gender = (String) user.getProperty("gender"); 
     String email = (String) user.getProperty("email"); 
     String birthday = user.getBirthday(); 

    if(email!=null){ 
    //perform your task here. 
    }else{ 
    Log.v("email","is empty"); 
    } 

     Log.d("FB----->","name: "+ name +" gender: "+ gender +" email: "+ email +" birthday: " +birthday); 

    }};

但它不是问题，我得到的是一个jsonexception而不是NPE。 – Ankit

尝试使用此方法获取电子邮件的价值 编辑：默认情况下，您将不会收到电子邮件，对于需要指定权限的电子邮件。

Session.StatusCallback statusCallback = new Session.StatusCallback() 
     { 

      @Override 
      public void call(Session session, SessionState state, Exception exception) 
      { 
       if(session.isOpened()) 
       { 
        Request.executeMeRequestAsync(session, new Request.GraphUserCallback() 
        { 

         @Override 
         public void onCompleted(GraphUser user, Response response) 
         { 

          if(user != null) 
          { 
           try 
           { 
            System.out.println("Graph Inner Json"+user.getInnerJSONObject()); 
            String email = user.getInnerJSONObject().getString("email"); 
           } 
          } 
         } 
        } 
       } 
      } 

YourActivityName.openActiveSession(this, true, statusCallback);

这是我们的openActiveSession()我们指定的权限

private static Session openActiveSession(Activity activity, boolean allowLoginUI, Session.StatusCallback statusCallback) 
    { 
     OpenRequest openRequest = new OpenRequest(activity); 
     openRequest.setPermissions(Arrays.asList("user_birthday", "email")); 
     openRequest.setCallback(statusCallback); 

     Session session = new Session.Builder(activity).build(); 

     if(SessionState.CREATED_TOKEN_LOADED.equals(session.getState()) || allowLoginUI) 
     { 
      Session.setActiveSession(session); 
      session.openForRead(openRequest); 

      return session; 
     } 

     return null; 
    }

而在最后，你应该在onActivityResult方法做，如：

if(Session.getActiveSession() != null) 
     { 
      Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data); 
     }
