I want my new activity to display JSON data - what am I doing wrong?

Question

I want MoviePage to display JSON data from a website when the relevant item in ListView is clicked.

Here is the code from my ListView page that opens a new activity when the item is clicked:

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String movieData = ((TextView) view).getText().toString();
            Intent newActivity = new Intent(ResultsActivity.this, MoviePage.class);
            newActivity.putExtra("title", movieData);
            startActivity(newActivity);
        }
    });

and here is the code of the page in which I wish to display the JSON data on

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

String keyword = getIntent().getExtras().getString("keyword");
    keyword = keyword.replaceAll("\\s", "+");

Intent newActivity1 = new Intent();
    setResult(RESULT_OK, newActivity1);

private String movieData(String keyword) {
    String jsonResult = null;

    try {
        URL url = new URL("https://omdbapi.com/?t=" + keyword);
        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
        InputStream input = httpURLConnection.getInputStream();
        Scanner scanner = new Scanner(input, "UTF-8").useDelimiter("\\A");
        jsonResult = scanner.hasNext() ? scanner.next() : "";
    } catch (Exception e) {
        e.printStackTrace();
    }
    return jsonResult;
}

ok then may i give you an sample of code to understand the process — Androider, Dec 03 '15 at 18:53
@pinktokyo89 What do you mean by display JSON data? Do you want to call a web service and then expect to return a JSON string/object that you need to handle and display in the application? — Apostrofix, Dec 03 '15 at 19:03
when you search for a movie on the website, JSON data appears for that movie etc title, year, plot. i would like to display the JSON data in my application. — pt89, Dec 03 '15 at 19:05

String keyword = getIntent().getExtras().getString("keyword");

Shouldn't this be,

String keyword = getIntent().getExtras().getString("title");

You should define your keys as constants so you don't make mistakes like this.

public static final String EXTRA_TITLE = "title";

newActivity.putExtra(EXTRA_TITLE, movieData);

Then when you take it out

getIntent().getExtras().getString(ClassWhereIDefinedMyKey.EXTRA_TITLE);

Instead store json object into sharedpreferences so you can retrive the object in any class of your application.You need to convert that object into string first and then store into sharedpreferences and vice versa for retriving link
