Application Theme in Android Studio

In this article, we'll dive into the world of themes in Android Studio and explore how to create and apply dynamic colors to our applications. We'll also examine some additional scenarios that allow us to control how colors are applied.

Before we get started, let's take a look at what we're working with. Our sample app is called Tip Time, a tip calculator app with options to customize the tip. In order to update the actual theme and apply dynamic color, there are a few changes that need to be made in the AndroidManifest.xml file for our application.

Locked Building Features - Animals Near You

One of the key features we'll be exploring is the ability to lock down certain building blocks within our app. This can be useful when working with dependencies that need to be managed carefully. For example, if we have a dependency on an API that requires a specific version of Retrofit, we can use Hilt to manage those cache dependencies.

Managing Cache Dependencies with Hilt

Hilt is a powerful tool that allows us to manage our app's dependencies in a way that's both efficient and easy to maintain. By using Hilt, we can easily switch between different versions of our dependencies without having to worry about manually updating our code.

Connecting to the API with Retrofit

Another important feature of our Tip Time app is its ability to connect to an API. We'll be using Retrofit to make this connection, and we'll explore how to manage those cache dependencies using Hilt.

Inverting Dependencies with Repositories

When working with dependencies, it's often necessary to invert them in order to decouple different parts of our app. This can help us maintain a clean and modular architecture that's easy to work with.

Bridging Requirements and Implementation

In this codelab, we'll be bridging the gap between requirements and implementation by updating our starter app to use the new features in Material Design 3. We'll learn how to create themes using our tooling and apply them to our app.

Dependencies Section

Before we get started, make sure that the material library is set to version 1.5 in your dependencies section.

Section I: Developing Real-World Apps

This codelab is part of our Android Basics in Kotlin training course, where you'll learn how to develop real-world apps using Kotlin and Android Studio. This sample app is one of the many projects you'll work on as part of this course.

Getting Started

To get started with this codelab, make sure you have a computer with Android Studio installed. If you're new to theming in Android, don't worry - we'll cover the basics and provide guidance throughout the process.

How Theme Attributes Relate to Each Other

Before we dive into creating themes, it's important to understand how theme attributes relate to each other. We'll explore this concept in more detail later on in the codelab.

Creating Themes Using Our Tooling and Applying Them

Once you have a solid understanding of how theme attributes work together, you can start creating your own themes using our tooling. We'll show you how to do this and provide guidance on applying them to your app.

Differentiating Between Existing Material Components and Material 3 Themes

One of the key benefits of Material Design 3 is its ability to differentiate between existing Material Components and Material 3 themes. We'll explore how to use these new features in our Tip Time app.

Comfortable with Modifying an App's Theme

Before we get started, make sure you're comfortable with modifying an app's theme. This will help you navigate the process of creating and applying dynamic colors to your app.

Familiar with Basic Theming Concepts in Android

If you're new to theming in Android, don't worry - we'll cover the basics and provide guidance throughout the process. Familiarity with basic theming concepts in Android is helpful but not required.

Additional Scenarios for Controlling Color Application

Throughout this codelab, you'll also examine some additional scenarios that allow you to control how colors are applied. This will give you a better understanding of how themes work and how you can use them to create dynamic and engaging user interfaces.

Screenshots of the Application with Dynamic Color Applied

Below are a couple screenshots of the application with dynamic color applied:

By following this codelab, you'll gain a deeper understanding of themes in Android Studio and learn how to create and apply dynamic colors to your applications. Whether you're new to theming or just looking to improve your skills, this codelab is the perfect place to start.

In this article, we've explored the world of themes in Android Studio and learned how to create and apply dynamic colors to our applications. We've also examined some additional scenarios that allow us to control how colors are applied. With this knowledge, you can take your app development skills to the next level and create user interfaces that are both beautiful and functional.

Final Thoughts

Before we wrap up, don't forget to check out the final version of our Tip Time app with dynamic color applied. We hope you've enjoyed this codelab and learned something new about theming in Android Studio. Happy coding!
