    • you can put the below code in oncreate. but it wont solve the problem it will only hide it. 

    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
StrictMode.setThreadPolicy(policy);

    what you actually need to do is put network related code in your createExpandableListViewDialog(); (the http request part) inside a background thread.
