Networking is one of the most important parts of Android applications. At the early stage, we wrote our own HTTP classes to handle networking. As time passed development got easier making us dependent on libraries. We use many libraries to get the work done faster but most of us do not analyse its limitations and drawbacks. Before using any library we need to analyse three things What, Why and How. One popular library which we use for Networking is Retrofit. In this post, let’s analyse these things and understand how the request gets processed inside Retrofit.
What?
Retrofit is a type-safe HTTP client for Android and Java.
Why?
Using Retrofit made networking easier in Android apps. As it has many features like,
Easy to connect to web-services by translating the API into Java or Kotlin.
Easy to add Headers and request types.
Easily Customisable, you can customise it and add say any convertors like Gson, JackSon, Moshi, Prtobuf, XML etc. You can also customise it to add different interceptors and cache.
