Getting Email Address By Using Facebook SDK 3.0.1 For Android

I'm currently developing an application which aims to authenticate any user by using Facebook acoount. I have a trouble in getting user email from user's account. My code is below

Solution 1:

Email is not a default field that's returned. Instead, you should create a meRequest, and pass it a parameter like: fields=email.

Request me = Request.newMeRequest(mCurrentSession, new GraphRequestCallback() {...});
Bundle params = me.getParameters();
params.putString("fields", "email,name");
me.setParameters(params);
me.executeAsync();

Solution 2:

you call just like this under regular things - only different you cannot directly user.email

System.out.println(user.asMap().get("email").toString());

regular :

        @Override
        public void onClick(View v) {
            // start Facebook Login
            Session.openActiveSession(Giris.this, true, new Session.StatusCallback() {

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

                  // make request to the /me API
                  Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {

                    // callback after Graph API response with user object
                    @Override
                    public void onCompleted(GraphUser user, Response response) {
                      if (user != null) {
                          System.out.println(user.getName());
                          System.out.println(user.getBirthday());
                          System.out.println(user.getFirstName());
                          System.out.println(user.getLastName());
                          System.out.println(user.getLink());
                          System.out.println(user.getUsername());
                          System.out.println(user.getLocation());
                          System.out.println("facebook user id" + user.getId());
                         System.out.println(user.asMap().get("email").toString());
                         // Session.OpenRequest open = new Session.OpenRequest(Login)
                      }
                    }
                  });
                }
              }
            });
        }

Solution 3:

just call this method will return user email id to you.

private void doSocialNetworkinWithFacebook()
    {
        // check for session 
         Session session=Session.getActiveSession();
         if (session != null && session.isOpened()) 
             {  
                // user is already login show
                    try
                        {
                            Session.OpenRequest request = new Session.OpenRequest(this);
                            request.setPermissions(Arrays.asList("email", "publish_actions"));
                        }
                    catch (Exception e)
                        {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                 Request.executeMeRequestAsync(session, new Request.GraphUserCallback() 
                        {
                          // callback after Graph API response with user object

                          @Override
                          public void onCompleted(GraphUser user, Response response) 
                          {
                              if (user != null) 
                               {

                                            strFirstName = user.getFirstName().toString();
                                            strLocation = user.getLocation().getProperty("name").toString();

Solution 4:

First add the appropriate permission, then fetch the email using the getProperty function.

permissions = Arrays.asList("email","languages","user_location","user_likes",    "user_education_history","user_work_history","user_hometown","user_about_me","user_status");

  Log.i(TAG, "user_email    : " + user.getProperty("email"));
