Answer 1

updateGUIState() needs to be run on the UI thread. A possible solution is to implement your GUI update in a Runnable, and call the runOnUiThread method with your runnable.

Answer 2

Try Handler.

Is onLoginResponse() is a callback function?
If it is, the problem can be solved by Handler.

In onLoginResponse(),

hRefresh.sendEmptyMessage(REFRESH);


    Handler hRefresh = new Handler(){
    @Override
    public void handleMessage(Message msg) {
    switch(msg.what){
         case REFRESH:
                /*Refresh UI*/
                updateGUIState();
                break;
       }
    }
};

To add to bhatt4982's response, you can also call handler.post(onLoginThread), where onLoginThread is a Thread whose runnable will run inside the GUI thread.
