Hope this will solve your problem

    onPreExecute() {
       // some code #1
    }

    doInBackground() {
        runOnUiThread(new Runnable() {
                    public void run() {
                        // some code #3 (Write your code here to run in UI thread)

                    }
                });
    }

    onPostExecute() {
       // some code #3
    }
