Introduction to Volley and Retrofit

Volley and Retrofit Library


In this video our topic is Volley and Retrofit.

In Android studio we have seen that we have different web services for parsing such as XML parsing, Pull parsing, and JSON parsing. We can also use third party library to make use of web service in Android.

Use of third party library makes networking easier and faster in Android applications.

Volley is a third party networking library. It is a HTTP library which supports effective network management in Android Applications.

Similarly we have another third party library that is Retrofit. It is a REST Client for Android and Java by square. It makes it relatively easy to retrieve and upload JSON via a REST web service.

To work with Retrofit, we need basically three classes,

Model class - to map JSON data.

Interfaces - defines the possible HTTP operations.

Retrofit.Builder class - Instance which uses interface.

Builder API - which allows defining the URL end point for the HTTP operation.
