Using socket.io in Asynctask android

Issue

I make a simple game with socket.io. It well execute but, when change UI view like textview it call Thread error. So, I decide to use AsyncTask when socket.on function. But before socket event come, onPostExecute is already done. How I can do this?

This is my code

 private class JoinAsync extends AsyncTask<Void,Void,Boolean> {
    Boolean isDone = false;
    JSONObject object;
    @Override
    protected Boolean doInBackground(Void... voids) {
        socket.on("join", new Emitter.Listener() {
            @Override
            public void call(Object... args) {
                object = (JSONObject)args[0];
                isDone = true;
                onPostExecute(true);
            }
        });
        return false;
    }
    @Override
    protected void onPostExecute(Boolean done) {
        if (done) {
            btnPlay.setEnabled(true);
            turnChanged();
            try {
                playertwoinfo.setText(object.get("nickname").toString() + "\n" + object.get("win").toString() + "승 " + object.get("lose").toString() + "패");
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }
}

Solution

1. Don't invoke methods of AsyncTask manually, they will be invoked.Remove onPostExecute(true); and it will work.
2. doInBackground() is invoked from a background thread which can not edit properties of views. Views can be changed from UI/main thread.
