解决方案

我想这是关系到图形API V2.4的变化，你指定你想从图形API返回的各个领域，这使得有必要

I have a Facebook login option in my Android app and I am trying to get the user's email unsuccessfully. After the user is logged in, and added to the Parse.com User table (with a valid access token), I request the Facebook user info, but only get it's id and name (even though the email is set as one of the permissions).

Here's my code (inside OnClickListener of my button):

ParseFacebookUtils.logInWithReadPermissionsInBackground(
    getActivity(), Arrays.asList("email", "user_friends"), new LogInCallback() {
        @Override
        public void done(ParseUser user, ParseException err) {
            //err is null

            if (user == null) {
                Log.d(TAG, "Uh oh. The user cancelled the Facebook login.");
            } else {
                GraphRequest.newMeRequest(
                    AccessToken.getCurrentAccessToken(),
                    new GraphRequest.GraphJSONObjectCallback() {
                        @Override
                        public void onCompleted(JSONObject user, GraphResponse response) {

                            Log.d(TAG, "user = " + user.toString());
                            //prints -> user = {"name":"my_fb_name","id":"my_fb_id"}
                        }
                    }
                ).executeAsync();                
           }
       });

解决方案

I guess this is related to a change in the Graph API v2.4 which makes it necessary that you specify every field you want to have returned from the Graph API.

Have a look at my answer at

• Facebook only returning name and id of user

regarding this

Concerning your actual problem, see

• https://developers.facebook.com/docs/android/graph#userdata

for an example on how to specify the fields for a GraphRequest

GraphRequest request = GraphRequest.newMeRequest(
        accessToken,
        new GraphRequest.GraphJSONObjectCallback() {
            @Override
            public void onCompleted(
                   JSONObject object,
                   GraphResponse response) {
                // Application code
            }
        });
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email");
request.setParameters(parameters);
request.executeAsync();
