[android help] Facebook sdk3 publish

After reading the FB publish tutorial

I'm trying to implement a simple publish, but in my application the user doesn't have to be logged in via FB. I want to open the loggin if needed and if so share.

And I got the next exception:

04-28 12:15:57.350: E/AndroidRuntime(32241): FATAL EXCEPTION: main
04-28 12:15:57.350: E/AndroidRuntime(32241): java.lang.UnsupportedOperationException: Session: an attempt was made to request new permissions for a session that has a pending request.

04-28 12:15:57.350: E/AndroidRuntime(32241):    at com.facebook.Session.requestNewPublishPermissions(Session.java:501)

My code:

    @Override
        public void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            boolean isFacebookResponse =
                    Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
            if (isFacebookResponse) {
                shareViaFacebook();
            }
        }

private void CheckFacebookLogin(){
        if(Session.getActiveSession() == null){
            logInToFacebook();
        }else{
            shareViaFacebook();
        }
    }

    private void shareViaFacebook() {
        Session session = Session.getActiveSession();

        if (session != null){

            // Check for publish permissions    
            List permissions = session.getPermissions();
            if (!isSubsetOf(PERMISSIONS, permissions)) {
                pendingPublishReauthorization = true;
                Session.NewPermissionsRequest newPermissionsRequest = new Session
                        .NewPermissionsRequest(this, PERMISSIONS);
            session.requestNewPublishPermissions(newPermissionsRequest);
                return;
            }

            Bundle postParams = new Bundle();
            postParams.putString("name", "Facebook SDK for Android");
            postParams.putString("caption", "Build great social apps and get more installs.");
            postParams.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
            postParams.putString("link", "https://developers.facebook.com/android");
            postParams.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");

            Request.Callback callback= new Request.Callback() {
                public void onCompleted(Response response) {
                    JSONObject graphResponse = response
                                               .getGraphObject()
                                               .getInnerJSONObject();
                    String postId = null;
                    try {
                        postId = graphResponse.getString("id");
                    } catch (JSONException e) {
                        Log.i(GA_CATEGORY,
                            "JSON error "+ e.getMessage());
                    }
                    FacebookRequestError error = response.getError();
                    if (error != null) {
                        Toast.makeText(getActivity()
                             .getApplicationContext(),
                             error.getErrorMessage(),
                             Toast.LENGTH_SHORT).show();
                        } else {
                            Toast.makeText(getActivity()
                                 .getApplicationContext(), 
                                 postId,
                                 Toast.LENGTH_LONG).show();
                    }
                }
            };

            Request request = new Request(session, "me/feed", postParams, 
                                  HttpMethod.POST, callback);

            RequestAsyncTask task = new RequestAsyncTask(request);
            task.execute();
        }
    }

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

    private void logInToFacebook() {
        String app_id = getString(R.string.app_id);

        Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

        Session session = new Session.Builder(getActivity())
                .setApplicationId(app_id)
                .build();
        session.addCallback(this);
        Session.setActiveSession(session);

        // Login
        if (!session.isOpened() && !session.isClosed()) {
            session.openForRead(new Session.OpenRequest(this)
                    .setCallback(this));
        } else {
            Session.openActiveSession(getActivity(), true, this);
        }
    }

The login code works. What I'm doing wrong?
