Implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0" Implementation "androidx.recyclerview:recyclerview:1.1.0" So we do need that Īll right then next step is we have to add below dependency in app adle. And first of all let’s add internet permission in AndroidManifest that is obvious, Because we are communicating with backend APIs. Let wait for sync of project, that recently you created. Open AndroidStudio and create a new android project with some template. I’m going to focus, this example on coroutines that work with Retrofit and MVVM.Īll right guys, so lets started quickly with this example app. You should know how retrofit works with MVVM. So idea is, I’m not going to details of these, you have to basic idea of these items. Check out this GitHub repository for the full implementation of this tutorial.Now, there are some requirements for this retrofit coroutines example app. We also went ahead and created a multipart request to the route using the Retrofit library. In this brief tutorial, we have learned what a multipart request is and what it looks like in a Ktor backend route. Var createUserRequest: CreateUserRequest? = null var fileName: String? = null multiPart.forEachPart ")įrom here, create your screen and call the ViewModel register function, parsing the actual arguments. This is what a multipart request looks like when you create it on a Ktor backend: This data is then uploaded to a server where the user is authenticated. A user usually selects a profile image and enters some details to register. In this tutorial, we will try and simulate how a user registers in an app. Browsers and HTTP clients frequently use it to upload files to the server. A multipart request is an HTTP request that HTTP clients create to send files and data to an HTTP server. These requests are typically used for file uploads and transferring multiple types of data in a single request (for example, a file along with a JSON object). Multipart requests combine one or more sets of data into a single, boundary-separated body. MIME, an Internet standard that extends the format of emails, is the source of multipart. How to use Retrofit to make network requests.Some basic knowledge of the Kotlin programming language.
A solid understanding of how to create and run Android apps.To follow along with this tutorial, the reader will need: In this tutorial, we will make a basic multipart request to a Ktor backend that accepts user profiles. Retrofit supports requests that are in parts. A multipart media type can be included in a part. The body can be any type of media and can contain text or binary data. One part consists of a header and a body. A multipart request is an HTTP request that HTTP clients create to send files and data to an HTTP server.Ī multipart message is made up of several parts.
