The obj.optString(“picture”) does not seem to get the picture url .jpeg as a string.

public static List<Photo> getPictures(AuthProvider provider, String source, String type) {
List<Photo> photos = new LinkedList<Photo>();
if (provider.getProviderId() == Constants.FACEBOOK) {
    final String BASE_URL_FACEBOOK = "https://graph.facebook.com/";
    String url = BASE_URL_FACEBOOK + source + "/feed";

    try {
        Response response = provider.api(url, MethodType.GET.toString(), null, null, null);

        Log.d("AndroidAppPhotoUtil", "Status " + response.getStatus() + " returned by facebook get query " + url);
        if (response.getStatus() == 200) {
            String respStr = response.getResponseBodyAsString(Constants.ENCODING);
            JSONObject resp = new JSONObject(respStr);
            JSONArray data = resp.optJSONArray("data");
            if (data != null)
                for (int i = 0; i < data.length(); i++) {
                    JSONObject obj = data.getJSONObject(i);
                    Photo p = new Photo();

                    p.setId(obj.optString("id"));
                    p.setPicture(obj.optString("picture"));


                    if (isEmpty(type) || type.equals(obj.optString("type"))) {
                        photos.add(p);
                    }

                }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
return photos;  
}

    I added put your JSON code inside a ‘{‘ and a ‘}’ and I did this:

        String respStr = "{\"id\":\"466138393436802_466165356767439\",\"from\":{\"name\":\"Dimitri Nicolopoulos\",\"id\":\"100004358376630\"},\"to\":{\"data\":[{\"name\":\"My Test Event\",\"start_time\":\"2012-11-13\",\"location\":\"Saewrreritvh\",\"id\":\"466138393436802\"}]},\"picture\":\"http://photos-a.ak.fbcdn.net/hphotos-ak-ash3/533694_123231957832083_231056016_s.jpg\",\"link\":\"http://www.facebook.com/photo.php?fbid=123231957832083&set=oa.160219667456793&type=1&relevant_count=1\",\"icon\":\"http://static.ak.fbcdn.net/rsrc.php/v2/yz/r/StEh3RhPvjk.gif\"}";
    JSONObject resp = new JSONObject(respStr);
    System.out.println(resp.get("picture"));

    This works. Also, your data is always null. The “data” is actually under the “to” key. So you can do

        String respStr = "{\"id\":\"466138393436802_466165356767439\",\"from\":{\"name\":\"Dimitri Nicolopoulos\",\"id\":\"100004358376630\"},\"to\":{\"data\":[{\"name\":\"My Test Event\",\"start_time\":\"2012-11-13\",\"location\":\"Saewrreritvh\",\"id\":\"466138393436802\"}]},\"picture\":\"http://photos-a.ak.fbcdn.net/hphotos-ak-ash3/533694_123231957832083_231056016_s.jpg\",\"link\":\"http://www.facebook.com/photo.php?fbid=123231957832083&set=oa.160219667456793&type=1&relevant_count=1\",\"icon\":\"http://static.ak.fbcdn.net/rsrc.php/v2/yz/r/StEh3RhPvjk.gif\"}";
    JSONObject resp = new JSONObject(respStr);
    JSONObject data = (JSONObject) resp.getJSONObject("to").getJSONArray("data").get(0);
    System.out.println(data);
