// For further information about the syntax of this request and JSON-C
// see the documentation on YouTube http://code.google.com/apis/youtube/2.0/developers_guide_jsonc.html
// Get are search result items
JSONArray jsonArray = json.getJSONObject("data").getJSONArray("items");
// Create a list to store are videos in
List<Video> videos = new ArrayList<Video>();
// Loop round our JSON list of videos creating Video objects to use within our app
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
// The title of the video
String title = jsonObject.getString("title");
// The url link back to YouTube, this checks if it has a mobile url
// if it doesnt it gets the standard url
String url;
try {
url = jsonObject.getJSONObject("player").getString("mobile");
} catch (JSONException ignore) {
url = jsonObject.getJSONObject("player").getString("default");
}
// A url to the thumbnail image of the video
// We will use this later to get an image using a Custom ImageView
// Found here http://blog.blundellapps.com/imageview-with-loading-spinner/
String thumbUrl = jsonObject.getJSONObject("thumbnail").getString("sqDefault");
// Create the video object and add it to our list
videos.add(new Video(title, url, thumbUrl));
}
