Answer 1

Get the permissions first

private static final List PERMISSIONS = Arrays.asList(
        "email","user_location");

The Method for getting the user information

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

        // callback when session changes state
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            /*
             * Session.getActiveSession().onActivityResult(activity1,64206,
             * -1,activity1.getIntent());
             */

            if (session.isOpened()) {

                List permissions = session.getPermissions();
                if (!isSubsetOf(PERMISSIONS, permissions)) {
                    Session.NewPermissionsRequest newPermissionsRequest = new Session.NewPermissionsRequest(
                            RegisterActivity.this, PERMISSIONS);
                    session.requestNewReadPermissions(newPermissionsRequest);
                    return;
                }
                // make request to the /me API
                Request.newMeRequest(session, new GraphUserCallback() {

                    @Override
                    public void onCompleted(GraphUser user, Response response) {
                        // TODO Auto-generated method stub
                        Log.d("",""+user);  
                        try {

                            name=user.getName();
                            email=user.getProperty("email").toString();
                            location=(user.getLocation().getProperty("name").toString());

                        } catch (Exception e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }

                    }
                }).executeAsync();

            }
        }
    });

isSubsetof method

private boolean isSubsetOf(Collection subset,
        Collection superset) {
    for (String string : subset) {
        if (!superset.contains(string)) {
            return false;
        }
    }
    return true;
}

put this code in onActivityResult

    @Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    Log.d("Activity result","  "+requestCode+"   "+resultCode+"    "+data.toString());
    Session.getActiveSession().onActivityResult(this, requestCode,
            resultCode, data);
}
