public class calc_stanica extends AsyncTask<String, Void, ArrayList<String>> { 
    ProgressDialog dialog; 

    @Override 
    protected void onPreExecute() {   

    } 

    protected ArrayList<String> doInBackground(String... passing) {  
String URLStr=passing[0];//as you are passing 1 url only so this will work for u  
ArrayList<String> arraylist=new ArrayList<String>(); 
     // here u do the things u wana do and add the String data to ArrayList<String> and return   

     return arraylist; 

    } 

    protected void onPostExecute(ArrayList<String> result) { 

    // do with ArrayList<String>   

    } 
}
