Students will learn how to create an emulator in Android Studio, configure device settings (such as hardware, display, and system image), and launch the emulator to simulate real-world usage. The topic also covers running apps on the emulator, testing app functionality, and troubleshooting common issues. By the end, learners will be able to confidently use emulators to build and test their Android apps.

Create Hello World App – Learn Android From zero to hero
In this section, learners build their very first Android application: the classic “Hello World” app. This hands-on exercise introduces the basics of project creation in Android Studio, including setting up a new project, choosing templates, and understanding the role of key files such as MainActivity and layout XML. Students will learn how to write simple code, connect it to the user interface, and run the app on an emulator or device. This milestone gives learners their first taste of Android development and builds the foundation for creating more advanced apps.

Android Studio Anatomy
This section provides a guided tour of Android Studio, the primary IDE for Android development. Learners will explore the key components of the interface, including the project structure, code editor, toolbar, and layout editor. It also explains the role of important panels such as the Project window, Logcat, Emulator, and Gradle console. By understanding the anatomy of Android Studio, students will gain confidence in navigating the environment, managing files, and using built-in tools efficiently setting a strong foundation for smooth app development.

Project Structure
This section explains the layout and organization of an Android project within Android Studio. Learners will explore the different folders and files that make up a project, including manifests, java (or kotlin), and res directories. It also covers the purpose of the Gradle build system, configuration files, and how resources like layouts, images, and strings are managed. By understanding the project structure, students will be able to navigate, customize, and maintain their apps more effectively—an essential skill for building scalable and professional Android applications.

Manifest File
This section introduces the AndroidManifest.xml file, the central configuration file of every Android app. Learners will discover how it defines essential app information, including the app’s package name, activities, permissions, hardware requirements, and app components. The module explains why the manifest is critical for app functionality and interaction with the Android operating system. By the end, students will understand how to read and modify the manifest file to properly register activities, declare permissions (like internet or camera access), and structure their apps for smooth performance on Android devices.

The Manifest 2
This section builds on the basics of the AndroidManifest.xml file, diving deeper into advanced elements and configurations. Learners will explore intent filters, app permissions in detail, and how to declare services, broadcast receivers, and content providers. It also covers app metadata, themes, and launch modes, showing how the manifest controls the way an app behaves and interacts with the Android system. By mastering these concepts, students will be able to customize their apps more effectively and ensure they meet Android’s requirements for security, compatibility, and performance.

What is Gradle
This section introduces Gradle, the build automation tool used in Android development.

The topic also explains Gradle’s role in handling project dependencies, build variants, and external libraries, making app development more efficient and flexible. By the end, students will know why Gradle is essential in Android projects and how it streamlines the process from writing code to creating a working app.

Java Folder
This section explains the purpose of the Java folder in an Android project. Learners will discover that this folder contains the source code of the application, written in Java or Kotlin, including all activities, classes, and logic that power the app. It also holds test code for debugging and quality assurance. By understanding the Java folder, students will learn where to write their app’s functionality, how different classes interact, and how the code integrates with layouts and resources to create a complete Android application.

Resource Folder
This section introduces the res (Resource) folder in an Android project, which stores all the non-code elements of an app. Learners will explore how this folder organizes resources such as layouts (layout), images and icons (drawable), app text (values/strings.xml), colors, styles, and more. The module explains how resources are linked to the app’s code, allowing developers to separate design from logic for easier management and localization. By the end, students will understand how to properly use the resource folder to build visually consistent, flexible, and maintainable Android applications.

Values Folder
This section explains the role of the values folder inside the Android resource directory. It stores XML files that define reusable resources such as strings, colors, dimensions, and styles. Learners will see how using the values folder helps keep code clean and organized by separating design elements (like text, themes, and UI styles) from the app’s logic. It also supports easier updates and localization, since text or style changes can be made in one place without modifying the code. By the end, students will understand how the values folder contributes to building scalable and maintainable Android apps.

Making a Resources App
