Volley in Android - Networking library
Volley is a networking library for Android that manages network requests. It bundles the most important features you’ll need, such as accessing JSON APIs, loading images and String requests in an easier-to-use package.
By using Volley for network operations you avoid the standard way to handle networking, HttpURLConnection. Another reason is asynchronicity. Volley handles asynchronicity by itself, there is no need to create Asynctask manually.
