12/31/2023 0 Comments Retrofit enqueue mvvmIt makes it relatively easy to retrieve and upload JSON (or other structured data) via a REST based webservice. This library, in my opinion, is the most important one to learn, as it will do the main job. Retrofit is a REST Client for Java and Android. Part 5: Handle RESTful Web Services using Retrofit, OkHttp, Gson, Glide and Coroutines (you’re here).Part 4: How to implement Dependency Injection in your app with Dagger 2.Part 3: All about that Architecture: exploring different architecture patterns and how to use them in your app.Part 2: How to start building your Android app: creating Mockups, UI, and XML layouts.Part 1: An introduction to the SOLID principles.Introduction: A roadmap to build a modern Android app in 2018–2019.It would be too complicated to recreate the functionality that these well-made libraries have to offer. Every good app does not try to reinvent the wheel but instead uses the most popular third party libraries to solve common problems. I am not going to talk about the native Android way to handle internet requests, because in the real world nobody uses it. We are going to combine multiple libraries at once to get a working result. You should definitely learn how to handle RESTful Web Services, as their correct implementation is the core knowledge while creating modern apps. ViewModelProviders.of(this).get(SpeciesListViewModel::class.java).These days almost every Android app connects to internet to get/send data. Private fun createViewModel(): SpeciesListViewModel = Source code package: .SpeciesRepository.kt class SpeciesRepositoryImpl(val apiService: Swapi) : SpeciesRepository The calling to web service happens here, and also includes receiving data and errors from web services. Source code package : .Swapi.kt interface Swapi getSpecies(): Call If you use Retrofit, you should already be familiar with this. The below code is the interface for the API. Retrofit is used as a remote datasource to connect to web services. You could clone the code from here and look at it along with this article. In this article, I will also cover common actions dealing with web services, including getting results, handling errors, and showing loading UI. The application will display a list of species in Star Wars. The demo application fetches the data from. Fragment/Activity: All about the UI (set up and update).ViewModel: Communicating to Repository then updating the data to UI (fragment/activity) respectively.Remote datasource: Connecting to web service. ![]()
