IntentService class not running AsyncTask on main ui thread. Method execute must be called from the main thread, currently inferred thread is worker

Question

I have a weird problem that occurred recently. I am calling a service named NotificationService which extends IntentService class. Now inside the onHandleIntent(Intent intent) method i making call to an async task. The code is given below:

@Override
protected void onHandleIntent(Intent intent) {
    defPrefs = PreferenceManager.getDefaultSharedPreferences(this);
    //int fiveMinutes = 1000 * 60 * 5;
    //Setting an alarm to call AlarmScheduler service now. This alarm scheduler service will set next days alarm to show notifications
    //based on the weekly schedule as obtained from server.
    Intent i = new Intent(NotificationService.this, ScheduleAlarms.class);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    //i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getService(NotificationService.this, 0, i, PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager alarmManager = (AlarmManager) NotificationService.this.getSystemService(Context.ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC, Calendar.getInstance().getTimeInMillis(), pendingIntent);//Use AlarmManager.INTERVAL_DAY instead of int number here.

    //Check if locally notifications are enabled by the user then only show notification depending on
    //if there are any latest notifications to be shown.
    if(defPrefs.getBoolean(getString(R.string.notifications),true)) {
        NotificationAsyncTask httpAsyncTask1 = new NotificationAsyncTask();
        httpAsyncTask1.mOnHttpResponseListener = new GetHomeResponse(intent);
        httpAsyncTask1.execute("http://" + HttpAsyncTask.IP_ADDRESS + "/v5/getResult");
    }else{
        Log.v("NotificationService","Disabled");
    }

}

Where NotificationAsyncTask is a private class defined inside this service. Now i am getting the error Method execute must be called from the main thread, currently inferred thread is worker.. I don't understand how this execute method is not running on the main thread? Please help.

onHandleIntent() is called on a background thread.

You cannot execute an AsyncTask from a background thread.

More importantly, you do not need an AsyncTask. Just take your doInBackground() code and put it in onHandleIntent().
