Here, <code>appContext</code> is the App context object and <code>appSdkConfig</code> is JSON object for holding the parameters (<code>appid</code>, <code>sfcode</code>) the App passes to the Nielsen App SDK via a JSON string. The appid is obtained from Nielsen operational support and is unique to the app.
