How to Use Ktor-Client in Your Android App
Ktor is an open-source framework for building asynchronous servers and clients in connected systems using the powerful Kotlin programming language. It runs on coroutines and was made by JetBrains.
Why we use Ktor’s
As in android already have a very powerful Retrofit library so why we need it. So Answer is Retrofit library is platform-dependent and if we want to use for Multiplatform application like Android recently launch then how we can achieve from retrofit so now ktor’s comes in mind for that solution.
Ktor’s uses coroutines internally for asynchronous programming which makes our code very clean and minimal just like coroutines did with suspend functions. Moreover it is as easy to add headers, serialization, logging etc in our app, as it is with Retrofit.
This guide will help you learn more about Ktor. We will set up Ktor client to make HTTP requests to a JSON API and display the data using kotlin.
Setting up Android project for Ktor-Client
Adding the required libraries
Let’s add all the necessary libraries that we need to process and display data. We need the following libraries:
you must add below line in the
Also required changes in project.gradle
here ‘kotlin-multiplatform’ is required if you creating application for multiplatform otherwise you can use “kotlinx-serialization” and also classpath “org.jetbrains.kotlin:kotlin-serialization” required for serialization and deserialization purpose.
Now lets add maven “https://kotlin.bintray.com/kotlinx” in setting.gradle (if using gradle version 7.3.3 or later) and also need to add plugin. Here we have used both if multiple form required then we can “kotlin-multiplatform” otherwise for Android “kotlinx-serialization” will be enough.
Now create a HttpClient class for handle All type of request, but here we are only using Android client.
Now lets create a model class to use any api with annotation Serializable.
After create model lets create a API class which will handle all request.
Now we create a repository class where all required method’s will be mention.
Now create a repository implementation class which will handle all request and response.
Now in our project we can use this class to call api method and will get the success or fail response in our caller class
