![]() I must mention that you can learn much more from the GitHub repository that I mentioned above in this blog. This way, we are able to fetch the data from the network using Retrofit with Kotlin Flow in Android. You can find the complete code for the implementation mentioned in this blog in the project itself.įirst, we need to set up our dependencies for the Retrofit as below:Ĭlass SingleNetworkCallViewModel ( private val apiHelper : ApiHelper, private val dbHelper : DatabaseHelper ) : ViewModel ( ) The project follows a basic MVVM Architecture for simplicity. I will be using the following project for the implementation part. Unit Testing ViewModel with Kotlin Flow and StateFlow.callbackFlow - Callback to Flow API in Kotlin.Instant Search Using Kotlin Flow Operators.Kotlin Flow Zip Operator for Parallel Multiple Network Calls.Retrofit with Kotlin Flow - YOU ARE HERE.Long-running tasks in parallel with Kotlin Flow.Creating Flow Using Flow Builder in Kotlin.This blog is a part of the series I have written on Flow API in Kotlin: We will learn to write the code inside the ViewModel with Kotlin Flow that follows a basic MVVM Architecture. In this blog, we will learn how to use Retrofit with Kotlin Flow in Android. Join my program and get high paying tech job: īefore we start, I would like to mention that, I have released a video playlist to help you crack the Android Interview: Check out Android Interview Questions and Answers. I am passionate about sharing knowledge through open-source, blogs, and videos. Step 1 : Add the following dependencies to your app’s adle file: dependencies else if(!Utils.I am Amit Shekhar, I have taught and mentored many developers, and their efforts landed them high-paying tech jobs, helped many tech companies in solving their unique problems, and created many open-source libraries being used by top companies. In this project i create a login screen and a post API request using with mvvm. So Let’s Start to Create an Android project with Java language. ![]() Retrofit also supports several serialization formats such as JSON and XML, and makes it easy to add custom headers and interceptors to your requests. It allows you to define an interface for your API calls using annotations, and then generates code to make those calls at runtime. Retrofit: Retrofit is a popular networking library for Android that simplifies the process of making HTTP requests to a remote data source.In the MVVM architecture pattern, the repository is typically used by the ViewModel to fetch and manage data. It’s responsible for retrieving, storing, and managing data. A repository provides a clean API to access and manage data from different sources such as a remote data source (API) or a local database. Repository: Repository is an architectural pattern that provides an abstraction layer between the app’s data sources and the rest of the app.It can be used to interact with repositories to fetch data from a remote data source or a local database. ViewModel does not contain any UI-related code and is responsible only for holding and managing data. It’s designed to survive configuration changes such as screen rotations, so that data can be retained across those changes. ViewModel: ViewModel is an Android architecture component that provides a way to store and manage UI-related data in a lifecycle-conscious way.Here’s a brief explanation of each one and how they work together. ViewModel, Repository, and Retrofit are three important concepts in Android app development. ![]()
