Android's dominance as a mobile operating system makes it one of the most significant platforms for app development. With the majority of the global smartphone market running Android, developers building for this platform are building for the largest addressable mobile audience. Getting the toolkit right determines how efficiently they can build, test, and deploy apps that perform well across Android's fragmented device landscape.
This post covers the six core tools that Android development teams rely on throughout the app creation process, from initial coding and testing through to design and deployment. For a broader view of what mobile app development involves, that context sits alongside these tool choices.
What an Android Development Toolkit Contains
A production-ready Android development toolkit covers six functional areas: an IDE for coding, testing, and debugging; an emulator for testing across virtual devices; a game engine for game-specific development; the official SDK for platform API access; an alternative IDE for .NET development; and a design tool for UI/UX prototyping. The tools below represent the standard choices in each category, informed by developer surveys and Android market data.
1. Android Studio: The Official Android IDE
Android Studio is Google's official IDE for Android development and the most widely used environment for building Android apps. It provides advanced code editing, a visual layout editor, built-in emulators, instant run debugging, and tight integration with the Android build tools.
As the official IDE, Android Studio receives updates alongside new Android API releases, ensuring compatibility with the latest platform features. It is the reference environment that most Android documentation, tutorials, and developer community resources assume you are using, which matters when onboarding new engineers or debugging unfamiliar issues.
2. Genymotion: Fast Android Emulator
Genymotion is a third-party Android emulator that provides significantly faster virtual device testing than the default Android Studio emulator. It offers cloud-based emulators across a wide range of device configurations, Android versions, and screen sizes, making it well suited for testing across Android's fragmented device landscape.
The built-in Android Studio emulator is sufficient for basic testing, but Genymotion's speed advantage is noticeable in iterative development cycles where the emulator is frequently restarted. For teams running automated testing across multiple device configurations, Genymotion's cloud emulators also remove the overhead of maintaining local device farms.
3. Unity: Game Engine for Android
For building games on Android, Unity is the leading engine. It provides a visual editor, C# scripting, 2D and 3D game development capabilities, and physics systems. Crucially, Unity games can be exported to Android, iOS, and other platforms from a single codebase, which makes it the practical choice for developers building mobile games for multiple platforms simultaneously.
Unity's accessible learning curve compared to alternatives like Unreal Engine makes it the engine of choice for most independent and mid-size studio Android game projects. For context on how mobile gaming has grown as an app development category, see our overview of mobile gaming apps.
4. Android SDK: Official Platform APIs and Tools
The Android Software Development Kit (SDK) provides the APIs, system images, emulators, and tools directly from Google for building Android apps. Every Android app uses the SDK: it is what gives code access to Android's platform features, including hardware sensors, notifications, storage, and network capabilities.
The SDK Manager, included with Android Studio, lets developers install specific SDK packages, platforms, and components required for development and testing across different Android versions. Because the SDK comes directly from Google, it is always the first to support new Android OS features, which matters for apps that need to launch with the latest capabilities.
5. Visual Studio with Xamarin: For .NET and C# Teams
For development teams working in C# and the .NET ecosystem, Visual Studio with Xamarin provides a professional Android development environment without requiring a full language switch. Xamarin allows developers to build Android (and iOS) apps using C# and .NET, sharing business logic and code across platforms while compiling to native performance.
Visual Studio with Xamarin is the right choice for organisations with existing .NET codebases, C# expertise, or enterprise integration requirements that align with the Microsoft ecosystem. For Android-first development without a .NET background, Android Studio remains the standard starting point. For more on app development approaches, that context sits alongside this tool decision.
6. Figma: UI/UX Design and Prototyping
Design and prototyping tools enable developers and designers to define the app's user interface and user experience before writing production code. Figma is now the standard for collaborative UI/UX design and interactive prototyping, providing real-time co-editing, component libraries, developer handoff features, and Android-specific design system support.
Prototyping in Figma before development begins reduces back-and-forth between designers and developers during implementation and catches UX problems when they are still cheap to fix. For more on the relationship between design decisions and app user experience, see our overview of user-centred app design.
Building for Android's Scale
These six tools cover the development lifecycle from initial coding through testing, game development, and design. Teams building for Android's global user base need tools that handle device fragmentation, keep pace with OS updates, and support efficient collaboration across development and design disciplines.

Frequently Asked Questions
What IDE do most Android developers use?
Android Studio is the dominant IDE for Android development. It is the official Google-supported IDE, receives updates alongside new Android platform releases, and is the environment assumed by most Android documentation and developer resources. Visual Studio with Xamarin is the preferred alternative for teams already working in the C# and .NET ecosystem.
What is the Android SDK and why is it required?
The Android SDK is the set of APIs, libraries, tools, and system images provided by Google for building Android apps. It gives code access to Android's platform features, including hardware capabilities, system notifications, storage, and network APIs. Every Android app requires the SDK. Android Studio includes the SDK Manager for installing the specific versions and components a project requires.
Is Unity only for game development on Android?
Unity is primarily used for game development, but it can also be used for interactive experiences, simulations, and augmented reality applications. For standard non-game apps, native Android development with Android Studio or cross-platform frameworks like React Native or Flutter are more appropriate. Unity's strength for Android development is specifically in game and interactive 3D applications where its physics, rendering, and cross-platform export capabilities provide significant advantages.
Why use Genymotion when Android Studio has a built-in emulator?
The Android Studio emulator is sufficient for basic development and testing. Genymotion offers faster emulator startup times, a broader range of pre-configured virtual devices, and cloud-based device testing that removes the need for local hardware. For teams doing frequent iterative testing or running automated test suites across multiple device configurations, Genymotion's speed and device variety advantages reduce testing overhead significantly.
What replaced Adobe XD for Android UI/UX design?
Figma has become the standard UI/UX design and prototyping tool, including for Android. Adobe discontinued XD in January 2024. Figma provides real-time collaborative editing, component libraries, Android-specific design system templates, and developer handoff features. For new Android projects, Figma is the default starting point for UI/UX work. Sketch remains in use at teams that established their workflow before Figma's dominance.
