`Error android.os.NetworkOnMainThreadException `. network operation on the main ui thread is wrong. use a thread or asynctask — Raghunandan, Jun 02 '14 at 08:41

For that you must have to call your method loadCategories() in asynch task in doInBackground method

because after 4.0 it does't allow to network call on your main ui theread.

    new AsyncTask<Void, Void, Void>() {
                @Override
                protected Void doInBackground(Void... params) {
                    // TODO Auto-generated method stub
                                   loadCategories();
                    return null;
                }
            }.execute();

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

This is not the correct way. You should use AsyncTask – Aniruddha Jun 02 '14 at 09:13
