Solution 1

You can get a good example of how to do here: http://www.androidhive.info/2012/01/android-json-parsing-tutorial/

Basically you have to use JSONObject and JSONArray, that you can get from getJSONObject() and getJSONArray(). Once you're on the good spot, use getJSONString() to get the desired value.

In your case it will be something like this:

JSONObject json = new JSONObject(response)
JSONArray jarray = json.getJSONArray("data");
for(int i = 0; i < jarray.length(); i++){
  JSONObject oneAlbum = jarray.getJSONObject(i);
  //get your values
  oneAlbum.getJSONString("name"); // this will return you the album's name.
}

Hope this will help you.

Solution 2

Try this

            Session.NewPermissionsRequest np = new Session.NewPermissionsRequest(this, "friends_photos");
            Session.getActiveSession().requestNewReadPermissions(np);
            Request rq = new Request(Session.getActiveSession(), userID + "/albums", null, HttpMethod.GET, new Request.Callback() {

                @Override
                public void onCompleted(Response response) {
                    JSONArray albumArr = response.getGraphObject().getInnerJSONObject().getJSONArray("data");

                    for (int i = 0; i < albumArr.length(); i++) {
                        JSONObject item = albumArr.getJSONObject(i);
                        System.out.println("id : " + item.getString("id"));
                        System.out.println("fromName : " + item.getJSONObject("from").getString("name"));
                        System.out.println("fromid : " + item.getJSONObject("from").getString("id"));
                        System.out.println("link : " + item.getString("link"));
                        System.out.println("cover_photo : " + item.getString("cover_photo"));
                        System.out.println("count : " + item.getString("count"));
                        System.out.println("created_time : " + item.getString("created_time"));
                        System.out.println("updated_time : " + item.getString("updated_time"));
                        System.out.println("can_upload : " + item.getString("can_upload"));

                    }

                }
            });
            rq.executeAsync();

Here I have a response from the facebook server that returns the list of albums of a selected user. I want to create an array for all the album names labeled "name" as well as the "link" and "cover_photo" to be ready to processed into a listview

Also, here is where the json data is returned (response). I will need to start parsing the data under response.

            Session.NewPermissionsRequest np = new Session.NewPermissionsRequest(this, "friends_photos");
            Session.getActiveSession().requestNewReadPermissions(np);
            Request rq = new Request(Session.getActiveSession(), userID + "/albums", null, HttpMethod.GET, new Request.Callback() {

                @Override
                public void onCompleted(Response response) {

                }
            });
            rq.executeAsync();

Any example would be helpful. I would like to study the code to get a better understanding on parsing json data.

This uses JSONObject json = jParser.getJSONFromUrl(url) to get the json data. How would I identify the data to be parsed as response in the callback?
Damien R. over 10 years

You can use json = new JSONObject(response); where response is a String with your json.

Just what I was looking for, a short example. Thanks!
