Unable to logout from facebook in android app

Question

I have try to integrate authentication through facebook successfully but my logout from facebook is not working properly.Following code snippet is my facebook login funcion

        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);
        getProfileInformation();
        Log.d("FB Sessions", "" + facebook.isSessionValid());
    }
    if (expires != 0) {
        facebook.setAccessExpires(expires);
    }
    if (!facebook.isSessionValid()) {
        facebook.authorize(this,
                new String[] { "email", "publish_stream" },
                new DialogListener() {
                    @Override
                    public void onCancel() {
                        // Function to handle cancel event
                    }

                    @Override
                    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();
                        getProfileInformation();
                    }
                });
    }
}

and following is logout function

@SuppressWarnings("deprecation")
public void logoutFromFacebook() {
    mAsyncRunner.logout(this, new RequestListener() {
        @Override
        public void onComplete(String response, Object state) {
            Log.d("Logout from Facebook", response);

            if (Boolean.parseBoolean(response) == true) {
                runOnUiThread(new Runnable() {

                    @Override
                    public void run() {
                        SharedPreferences.Editor editor = mPrefs.edit();

                        editor.clear();
                        editor.commit();
                    }
                });
            }
        }
    });
}

How can I make log out function in a proper way. Please do replay...

Answer 1

Session session = Session.getActiveSession();
session.closeAndClearTokenInformation();

Try that for logging out instead.
