2. Declaring DependenciesĪfter creating a new project, declare the following dependencies in your adle.

We'll be using the API provided by JSONPlaceholder-this is a fake online REST API for testing and prototyping.Ĭheck out my previous post, Get Started With Retrofit 2 HTTP Client, to learn how to execute GET requests and how to integrate Retrofit with RxJava.įire up Android Studio and create a new project with an empty activity called MainActivity. I'll also show you how to integrate with RxJava and how to cancel requests. In this tutorial, I will explain how to use Retrofit 2 to handle network requests by building a simple app that will perform POST requests, PUT requests (to update entities), and DELETE requests.

Retrofit, on the other hand, is a well-planned, documented and tested library that will save you a lot of precious time and headaches.

Simple Framework: 2:converter-simpleframeworkĭeveloping your own type-safe HTTP library to interface with a REST API can be a real pain: you have to handle many aspects, such as making connections, caching, retrying failed requests, threading, response parsing, error handling, and more.

Instead, it ships support for the following JSON converter libraries to handle that: Also, Retrofit does not have a built-in JSON converter to parse from JSON to Java objects. Behind the scenes, Retrofit makes use of OkHttp (from the same developer) to handle network requests. Like most open-source software, Retrofit was built on top of some other powerful libraries and tools. GET, POST, PUT, PATCH, and DELETE requests can all be executed. This powerful library makes it easy to consume JSON or XML data, which is then parsed into Plain Old Java Objects (POJOs).

In this tutorial, I'll show you how to use one of the most popular and often recommended HTTP libraries available for Android. Retrofit makes it easy to connect to a REST web service by translating the API into Java interfaces. Retrofit is a type-safe HTTP client for Android and Java.
