![]() You can access this tutorial’s code on GitHub. Did you know that Retrofit takes 312ms to carry out one discussion? That is super fast.Ĭheck out other ways to use Retrofit in their official documentation. We have learned how to use Retrofit and its advantages and disadvantages. We have learned that networking is a crucial factor in mobile application development. Step 2 – Adding retrofit to our applicationĪdd the following dependencies to your app-level adle file. Select Finish and wait for the project to build. Open Android Studio and Start a new Android Studio Project -> Empty Activity. Step 1 – Create a new Android studio project The reader should have basic knowledge of making network requests, JSON, and REST APIs.The reader should have a beginner level understanding of Java and XML.Interface class- This Java class is used to define endpoints.Retrofit instance - This Java class is used to send requests to an API.Model class - This class contains the objects to be obtained from the JSON file.It does not support setting priorities.It requires other libraries such as Glide and Picasso. It supports both synchronous and asynchronous network requests.It supports post requests and multipart uploads.It enables direct communication with the web service.Retrofit resolves issues before sending an error and crashing the app.Retrofit pools connections to reduce latency.It caches responses to avoid sending duplicate requests.It alternates IP addresses if there is a connection to a web service failure.It manages the process of receiving, sending, and creating HTTP requests and responses.Retrofit is used to perform the following tasks: Most developers since then have switched to using Retrofit to make API requests. Retrofit was even better since it was super fast, offered better functionality, and even simpler syntax. Retrofit is a type-safe HTTP networking library used for Android and Java. Still, there was room for growth when it came to networking. Volley offered something better: It was faster, provided better functionality, a simpler syntax, etc. Networking on the main thread stopped after the Honeycomb version was released. ![]() This made applications less user-friendly since screens would “freeze”. Initially, developers did networking on the main thread. Applications are either sending or receiving information. Most, if not all mobile applications incorporate networking on some level. Use your repository to enqueue a call and update your LiveData in its callbacks.Networking is a crucial factor in mobile development. We’ll start off, firstly with the normal way to do it. We’ll also be going through as if we already have Retrofit set up in our app. This tutorial does of course, require you to know about MVVM, LiveData, and Retrofit. There is a workaround to this which we have as one of our 3 solutions, but we’ll get to that later.įor this tutorial, I’ll be using the JSONPlaceholder API. Why doesn’t LiveData work so well with API calls, you may ask? We could potentially create an adapter that maps the Retrofit Call to the LiveData, but the underlying problem here is the lack of the ability to return an error value. While MVVM can still just as easily make use of RxJava, there are reasons why you wouldn’t want to (that we won’t get into here) and instead, choose the wonderful world of LiveData. It only made perfect sense to return API calls as Observables that can be easily mapped and manipulated in ways limited only by imagination. Back in the good ol’ days of MVP, the combination of RxJava and Retrofit was almost an absolute.
