Free online courseAndroid for beginners

Course Description

Start building real Android apps from the ground up, even if you have never opened Android Studio before. This free beginner-friendly course guides you through the complete first steps of Android development: preparing your computer for Java, installing and configuring Android Studio, creating your first project, and running apps on an emulator so you can test changes quickly.

As you move forward, you will learn how an Android app is structured and how activities behave throughout their lifecycle, helping you avoid common mistakes that cause crashes, lost data, or confusing navigation. You will also gain practical confidence with the Android Studio interface and productivity features so that writing, organizing, and improving code becomes smoother over time.

A major focus is building interfaces that work well across many screen sizes. You will practice creating layouts, styling widgets, using density-independent measurements, assigning IDs, and responding to user actions through event handling. From clicks and long presses to gestures, you will learn how to connect what the user does to what the app should do, turning static screens into interactive experiences.

To help you create apps that feel complete, the course introduces core components that power modern Android features. You will explore fragments for flexible UI design, menus, transitions, and the use of intents to navigate between screens and pass data. You will also learn how broadcast messages work and what it takes to receive them safely in an app.

Performance and reliability are covered with practical approaches to threading and handlers so your interface remains responsive while work happens in the background. You will also study services, including bound services, to understand how apps can run tasks beyond a single screen. For data and media, you will work with list-based interfaces, saving information locally with SQLite, handling camera and image effects, and adding notifications and preferences for a more polished user experience.

Finally, you will connect your workflow to real distribution practices by working with GitHub and producing an APK, giving you a clear path from learning to sharing what you build. If your goal is to enter app development, strengthen your programming portfolio, or simply understand how Android apps are made, this course provides a hands-on foundation you can build on immediately.
