Hey, first time using an API, I was wondering if anyone could give me tips/suggestions based on my code. Thanks.

class results extends AsyncTask{

protected void onPreExecute(){
    listViewMovies.setText("");
}

protected String doInBackground(Void... urls){

    String results = getIntent().getStringExtra("Time String");//Criteria 1
    String results2 = getIntent().getStringExtra("Genre String");//Criteria 2
    String results3 = getIntent().getStringExtra("Decade String");//Criteria 3

try {
    URL url = new URL(https://api.themoviedb.org/3/movie/550?api_key=11111111notmyapikeyappend_to_response=results,results2,results3)
    HttpsURLConnection urlconnection = (HttpsURLConnection) url.openConnection();

    try{
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlconnection.getInputStream()));

        StringBuilder stringBuilder = new StringBuilder();
        String line;
        while ((line = bufferedReader.readLine()) != null){
            stringBuilder.append(line).append("\n");

        }

    bufferedReader.close();
        return stringBuilder.toString();

    }

    finally {
        urlconnection.disconnect();
        }
    }

    catch (Exception e){

    }


    protected void onPostExecute(String Result){

        if(Result == null){
            Result = "Error";
        }

        listViewMovies.setText(Result);

        };
    }
}

}
