Volley is an HTTP library that makes networking for Android apps easier and most importantly, faster
At a high level, you use Volley by creating a RequestQueue and passing it Request objects. The RequestQueue manages worker threads for running the network operations, reading from and writing to the cache, and parsing responses. Requests do the parsing of raw responses and Volley takes care of dispatching the parsed response back to the main thread for delivery
Retrofit is a REST Client for Android and Java by Square. It makes it relatively easy to retrieve and upload JSON (or other structured data) via a REST based webservice. In Retrofit you configure which converter is used for the data serialization
