It is not okay to do the Network Operation on main thread.. You can use AsyncTask to perform such operations and handle the result in onPostExecute method. 

class YourNetworkingTasks extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... voids) {
    try{
        HttpServices post = new HttpServices ("http://sotem.com.mx/WebServices/controller.php");
        post.add("funcion", "test");

        String respuesta = post.getRespueta();
        Log.d("Output", respuesta);
        // DON'T DO ANY UI CHANGES LIKE TOAST FROM BACKGROUND THREAD.. Toast.makeText(getApplicationContext(),"Cool: "+respuesta, Toast.LENGTH_SHORT).show();

    }catch (Exception ex) {
       // DON'T DO ANY UI CHANGES LIKE TOAST FROM BACKGROUND THREAD..  Toast.makeText(getApplicationContext(),"error: "+ex.toString(), Toast.LENGTH_SHORT).show();
    }
return null;
}

protected void onPostExecute(RSSFeed feed) {
    // TODO: YOU CAN MAKE U.I. Changes Like Display text in TextView, TOAST HERE.
    // TODO: do something with the result
  }
}

And write new YourNetworkingTasks().execute(); to run that code in background thread.

Please also not that since you are using http and not https you may get Network Security Exception and may not get any output due to recent security change in android.
