Introduction

You are required to develop your app in Android Studio with Jetpack Compose – a modern toolkit for building native UI. Compose allows developers to build user interfaces, explore and test them and develop intuitive code using Kotlin. Using Compose, you can iterate faster and give your users a better user experience. This reading will recap some key concepts previously introduced in this program on Android Studio and Jetpack Compose.

About Android Studio

As mentioned earlier, to create apps for the diverse devices of the Google ecosystem, you need to use an application called Android Studio , which is provided by Google for free. Android Studio is technically an Integrated Development Environment or IDE that runs on desktop computers. You can create apps in Android Studio by using different languages, such as Kotlin or Java, and different UI paradigms, like XML Layouts or Jetpack Compose. Android Studio is equipped with all the tools you need to create an Android app such as a text editor for typing code. It also includes a compiler to convert the typed code into binary encoding that the processor in which the app will run can understand. The included debugger system helps you locate and eliminate bugs and an interface system helps you design interfaces.

Installing Android Studio

To start using Android Studio all you need to do is download and install it. However, it's no use developing apps if you cannot distribute them. That’s why you have to sign up for a Google Developer account and enrol in the Google Developer Program which allows you to distribute your apps through the Google Play Store. You will find the links you need in the Additional resources section of this lesson. For more about installing Android Studio, you can review the Setting up Android Studio video in the Create the user interface in Android Studio course.

Jetpack Compose

Jetpack Compose is a UI toolkit for building Android apps with the Kotlin programming language. Compose provides a set of building blocks called composables that can be combined to create complex UI elements and layouts. It also includes a number of pre-built UI components and supports animation, accessibility and other features that are important for building modern Android apps. Here are the main advantages of using Jetpack Compose for building Android apps:

• Jetpack Compose uses a declarative programming style, which makes it easy to understand and reason about the structure of your UI. This can make it easier to write, test and maintain your app's code.

• Better developer experience: Jetpack Compose includes a live preview feature that allows developers to see their changes in real time as they code, which can help speed up the development process.

• Jetpack Compose is built on top of the Kotlin programming language and its coroutines, and it allows you to build reactive UIs, which means you can easily update the UI in response to changes in the underlying data.

• Jetpack Compose uses a more efficient layout engine and a new animation framework, which can result in faster and smoother performance for your app.

• With Jetpack Compose, you can create composable functions that can be reused across different parts of your app, which can help make your code more organized and maintainable.
