getting null for user email - restfb

Question

I've recently started working on manual login flow of facebook. And followed this blog to get the access token and using restfb to access user information.
Below is the code snippet as mentioned - Fetching Single Objects:

FacebookClient facebookClient = new DefaultFacebookClient(ACCESS_TOKEN, APP_SECRET);
User user = facebookClient.fetchObject("me", User.class);

I'm successfully able to get the user's name, first name and last name but it returns null for email (user.getEmail();).

My facebook app has default permissions as:

Anyone help me how can I access the user email?

UPDATE

I've been trying the graph-api explorer to see what I'm getting for email graph-api explorer and it says Field is empty or disallowed by the access token. What do I'm supposed to do to fix this?

Try this

User me = client.fetchObject(yourId, User.class,Parameter.with("fields", "email"));

Just put all the parameters you want separated by commas eg. ("fields", "email,first_name,last_name") etc – Fast Engy Sep 23 '15 at 02:26
Here you can find the available fields: https://developers.facebook.com/docs/graph-api/reference/user – Gabor Meszaros Sep 04 '16 at 11:47

Either the user doesn't have his email listed or you aren't requesting the email permission in scope.

Check that you have email permissions with a request to me/permissions

In that blog post mentioned the email should be set in the getLoginRedirectURL. To ensure this when you go through a login dialog check that the Facebook login dialog asks for email permission.

This is also described in the manual flow

https://www.facebook.com/dialog/oauth? client_id={app-id} &redirect_uri={redirect-uri}&scope=email

how do I request for `email` permission in scope? – Mohammad Faisal Oct 11 '14 at 21:01
thanks for the answer. I've got certain questions now... what if user edit the preference and uncheck not to provide email? How can I get his email later? Can more than one scope be requested and how? – Mohammad Faisal Oct 11 '14 at 22:06
