Android: Parsing JSON data from a String

A very handy built-in class to have is JSONTokener which I used for my Diablo II Runewords app.

view sourceprint?

01.public RunewordParser(String data) throws JSONException {

02.  // Parse String "data"

03.  JSONObject json = (JSONObject) new JSONTokener(data).nextValue();

04. 

05.  // Some primitive data types

06.  stones = json.getString("stones");

07.  matched = json.getInt("matched");

08.  onlyComplete = json.getBoolean("only_complete");

09. 

10.  // Dealing with arrays

11.  JSONArray runewords = json.getJSONArray("runewords");

12.  for (int i = 0; i < runewords.length(); i++) {

13.    Runeword runeword = new Runeword(runewords.getJSONObject(i));

14.    this.runewords.add(runeword);

15.  }

16.}

That should be enough to get you started. If you've got any questions, leave a comment.
