Initiating Communication via Smartphone

Android and iOS provide good native support for HTTPS and JSON.

• The Android system uses JSONObject and JSONArray to assemble and parse JSON objects and arrays, and HttpURLConnection to initiate HTTPS requests.

• The iOS system uses NSJSONSerialization to assemble and parse JSON data, and URLSession to initiate HTTPS requests.

Of course, you can also use third-party HTTPS and JSON libraries.
