Auto post on Facebook on user behalf

Hi guys! I have developed a physics based (Box2d) game for android using Processing and I want to add score sharing option to it so that the user can share his/her best score on their facebook timeline after the game. I have setup Facebook SDK in eclipse. I have searched over internet and found this solution:

public class FacebookConnector {
            private static final String APP_ID = "****************";
            private Facebook facebook;
            private AsyncFacebookRunner mAsyncRunner;
            String FILENAME = "AndroidSSO_data";
            SharedPreferences mPrefs;

            public FacebookConnector() {
                facebook = new Facebook(APP_ID);
                mAsyncRunner = new AsyncFacebookRunner(facebook);
            }

        public void loginToFacebook() {
            mPrefs = getPreferences(MODE_PRIVATE);
            String access_token = mPrefs.getString("access_token", null);
            long expires = mPrefs.getLong("access_expires", 0);

            if (access_token != null) {
                facebook.setAccessToken(access_token);
            }

            if (expires != 0) {
                facebook.setAccessExpires(expires);
            }

            if (!facebook.isSessionValid()) {
                facebook.authorize(LocalPakistaniGames.this,
                        new String[] { "email",
                        "publish_stream" }, new DialogListener() {

                    public void onCancel() {
                        // Function to handle cancel event
                    }

                    public void onComplete(Bundle values) {
                        // Function to handle complete event
                        // Edit Preferences and update facebook acess_token
                        SharedPreferences.Editor editor = mPrefs.edit();
                        editor.putString("access_token",
                                facebook.getAccessToken());
                        editor.putLong("access_expires",
                                facebook.getAccessExpires());
                        editor.commit();
                    }

                    public void onError(DialogError error) {
                        // Function to handle error

                    }

                    public void onFacebookError(FacebookError fberror) {
                        // Function to handle Facebook errors

                    }

                });
            }
        }

        public void logoutFromFacebook() {

                        // User successfully Logged out

                                }
                            });
                }
            });
        }
    }

Its working fine and giving a pre-filled dialog box where user can either share or close the dialog box. I have checked and It's sharing correctly on Facebook timeline. But the problem is that it is not using Facebook app installed on the device. Its using chrome on my device to login to Facebook. Is there any way to force it to use Facebook app for android instead of going to chrome (or any other browser)??
