Create your first Kotlin multiplatform mobile application in Android Studio
In this article, you are going to build a simple hello world application that will run in Android and IOS with a single codebase using Kotlin programming language.
Firstly, I will like to explain what is Multiplatform, its benefits, and how to implement it in your codebase.
What is Multiplatform?
If a software program is developed for multiple operating systems, it is considered to be “multiplatform.” meaning its capable of running on two or more different hardware platforms.
I believe it's clear now, lets get to know what is Kotlin Multiplatform
Kotlin Multiplatform
Kotlin Multiplatform Mobile allows you to use a single codebase for the business logic of iOS and Android apps. Sharing code between mobile platforms is one of the major Kotlin Multiplatform use cases. With Kotlin Multiplatform Mobile (KMM), you can build multiplatform mobile applications sharing code, such as business logic, connectivity, and more, between Android and iOS.
