I am having trouble getting email from Facebook in my app. I have googled a lot and came across many answers but nothing is working in my case. I followed the same method described here, but the value returning is null. Below given is my code. And also I have added User & Friend permissions as email in the facebook app. It would be of great help if someone could point out the mistake I might be doing.
    private void makeMeRequest(final Session session) {
    Request request = Request.newMeRequest(session,
            new Request.GraphUserCallback() {
                @Override
                public void onCompleted(GraphUser user, Response response) {
                    if (session == Session.getActiveSession()) {
                        if (user != null) {
                            profilePictureView.setProfileId(user.getId());
                            facebook_id = String.valueOf(user.getId());
                            fullName.setText(user.getName());
                            if (user.asMap().get("email") != null)
                                email.setText(user.asMap().get("email")
                                        .toString());
                        }
                    }
                    if (response.getError() != null) {
                    }
                }
            });
    Bundle params = request.getParameters();
    params.putString("fields", "email,name");
    request.setParameters(params);
    request.executeAsync();
}
