How to get Facebook Additional Permissions with android sdk 3.0 beta?

Question

I'm developing a simple Facebook app for Android using the official sdk beta 3.0.

I would to get additional permissions for user logged (user_likes, user_interests, friends_likes, etc...) without using the LoginButton (as explained here https://developers.facebook.com/docs/howtos/androidsdk/3.0/login-with-facebook/ ) and, in fact, I'm getting the additional permissions with method

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        List<String> permission=new ArrayList<String>();
        permission.add("user_birthday");
        permission.add("user_likes");
        permission.add("user_questions");
        permission.add("user_interests");
        permission.add("user_relationships");
        permission.add("user_groups");
        permission.add("user_religion_politics");
        permission.add("friends_birthday");
        permission.add("friends_interests");
        permission.add("friends_likes");
        permission.add("friends_groups");
        permission.add("friends_questions");
        permission.add("friends_relationships");
       // this.openSession();
          this.openSessionForRead(app_id, permission);

    } 

and actually, it opens the login view asking for permission to have additional permissions.

Now, I would know how to obtain the additional permissions because, when I'm calling user.get* * () it not showing other methods except those for base informations.

Thanks!

I'm getting a Null.pointer.exception using

private GraphObject mUser; ... // Assign the user object you get from a call to get the user's info

String religion = mUser.getProperty("religion").toString();

here my logcat:

Answer 1

You can additional permissions after the session has created. without closing the session

Session.NewPermissionsRequest newPermissionsRequest = new Session
                    .NewPermissionsRequest(this, Arrays.asList("user_groups"));

            session.requestNewReadPermissions(newPermissionsRequest);

Answer 2

Add a method to the com.facebook.Session.java class within the Facebook Android SDK project:

public static Session openActiveSession(Activity activity, boolean allowLoginUI, StatusCallback callback, List permissions) {
    return openActiveSession(activity, allowLoginUI, new OpenRequest(activity).setCallback(callback).setPermissions(permissions));
}

From your code you can then call directly

Session.openActiveSession(LoginActivity.this, true, new Session.StatusCallback() {

    // callback when session changes state
    @Override
    public void call(Session session, SessionState state, Exception exception) {

        if (session.isOpened()) {

            //YOU CALLBACK CODE

        }
    }

}, Arrays.asList("email","OTHER_PERMISSIONS_YOU_WANT_TO_REQUEST"));

Answer 3

GraphUser only has a limited set of common properties you can pull and read, ex: birthday. To read something else like say religion you could do the following:

private GraphObject mUser;
...
// Assign the user object you get from a call to get the user's info

String religion = mUser.getProperty("religion").toString();

Hopefully this answers your question.

Answer 4

检查mUser是否为空。

Answer 5

Here is the link to the Graph api explorer . You just select right application and click create access token. Into popup dialog you can set prefered permission.

As you can see in the original example called: "SessionLoginSample" - after you receive TOKEN, you can call JSON file structure which is available from " https://graph.facebook.com/me?access_token=insert_your_real_token&format=json "

That json file is response with all information that is available due to user's private settings.

I hope I helped.

Answer 6

    Session.Builder bui = new Builder(this); //should be an activity
    Session session  = bui.build();
    Session.OpenRequest openRequest = new OpenRequest(context);
    List<String> permission=new ArrayList<String>();
        permission.add("user_birthday");
        permission.add("user_likes");
        permission.add("user_questions");
        permission.add("user_interests");
        permission.add("user_relationships");
        permission.add("user_groups");
        permission.add("user_religion_politics");
        permission.add("friends_birthday");
        permission.add("user_location");
        permission.add("friends_likes");
        permission.add("friends_groups");
        permission.add("user_education_history");
        permission.add("friends_relationships");
        permission.add("email");

    openRequest.setPermissions(permission);
    Session.setActiveSession(session);//This will take care of the null pointer
    openRequest.setCallback(this);//the callback
    session.openForRead(openRequest);

Session.setActiveSession(session);
IS the missing line in your code... (and the builder)
