What does happens when a screen is rotated? Before we think about this question let’s try to understand how does Android deal with that.

When a user rotates their phone the configuration of the Activity changes, so android OS destroys the Activity and recreates it again.

Behind the scenes; when the device orientation changes, first the Activity will disappear for a millisecond when the onPause, onStop, and onDestroy methods are called. After a few milliseconds, the activity will be restarted and the onCreate, onStart, and onResume methods are called.

Say Hello to Jetpack Compose and Compare with XML

Introduction

Hi everyone 👋 I will try to explain Jetpack Compose Fundamentals and Why should I use Jetpack Compose. Jetpack Compose is important because it is a new way of building modern UI in Android. Let’s dive into the UI development in Android without XML.

In my opinion, Jetpack Compose is the future of Android UI development and we must adopt fastly.

What is Jetpack Compose?

Jetpack Compose is Android’s modern toolkit for building native UI. It simplifies and accelerates UI development on Android – Google

Jetpack Compose is a modern toolkit that allows us to build our screens in a declarative approach writing less code. Android UI Development is now more powerful and more decoupled.

Before Jetpack Compose, we were using XML layouts to build the native UI. We had a very dependent structure when we build the screens with XML. Also, fragments are very heavy components for the UI. Jetpack Compose allows us to build the same UI with a declarative UI approach and with less code.

Why should I use Jetpack Compose?

In my opinion, it’s more than easy from XML and Kotlin ❤️

If we look technically:

Declarative UI is cleaner, readable, and performant than Imperative UI.
Compose allows you to do more with less code compared to XML.
Compose is Intuitive. This means that you just need to tell Compose what you want to show the user.
Compose is compatible with all your existing code: you can call Compose code from Views and Views from Compose. Also integrated with many Jetpack Libraries.
Compose improves your build time and APK size.

XML Design vs Jetpack Compose

Composition — Recomposition — State Management

Each composables has a initial compositon. Initial composition runs only when we see a view at first time in screen.

Composables can hold a state and re-run on state changes. This is called Recomposition.
