Everything you need to build on Android
Android Studio is Android's official IDE. It is purpose-built for Android to accelerate your development and help you build the highest-quality apps for every Android device.
Code and iterate faster than ever
Based on IntelliJ IDEA, Android Studio provides fast turnaround on your coding and running workflow.
Android Studio's Apply Changes feature lets you push code and resource changes to your running app without restarting your app—and, in some cases, without restarting the current activity. This flexibility helps you control how much of your app is restarted when you want to deploy and test small, incremental changes while preserving your device's current state.
Intelligent code editor
The code editor helps you write better code, work faster, and be more productive by offering advanced code completion, refactoring, and code analysis. As you type, Android Studio provides suggestions in a dropdown list. Simply press Tab to insert the code.
Fast and feature-rich emulator
The Android Emulator installs and starts your apps faster than a real device and lets you prototype and test your app on various Android device configurations: phones, tablets, Android Wear, and Android TV devices. You can also simulate a variety of hardware features such as GPS location, network latency, motion sensors, and multi-touch input.
Code with confidence
At every step, Android Studio helps ensure that you're creating the best code possible.
Code templates and sample apps
Android Studio includes project and code templates that make it easy to add well-established patterns such as a navigation drawer and view pager. Start with a code template or right-click an API in the editor and select Find Sample Code to search for examples. You can also import fully functional apps from GitHub directly from the Create Project screen.
Android Studio provides a robust static analysis framework and includes over 365 different lint checks across the entirety of your app. Additionally, it provides several quick fixes that help you address issues in various categories, such as performance, security, and correctness, with a single click.
Testing tools and frameworks
Android Studio provides extensive tools to help you test your Android apps with JUnit 4 and functional UI test frameworks. With Espresso Test Recorder, you can generate UI test code by recording your interactions with the app on a device or emulator. You can run your tests on a device, an emulator, a continuous integration environment, or in Firebase Test Lab.
Configure builds without limits
Android Studio's project structure and Gradle-based builds provide the flexibility you need to generate APKs for all device types.
Robust and flexible build system
Android Studio offers build automation, dependency management, and customizable build configurations. You can configure your project to include local and hosted libraries, define build variants that contain different code and resources, and apply various code shrinking and app signing configurations.
Designed for teams
Android Studio integrates with version control tools, such as GitHub and Subversion, so you can keep your team in sync with project and build changes. The open source Gradle build system lets you tailor the build to your environment and run on a continuous integration server such as Jenkins.
Optimized for all Android devices
Android Studio provides a unified environment where you can build apps for Android phones, tablets, Android Wear, Android TV, and Android Auto. Structured code modules allow you to divide your project into units of functionality that you can independently build, test, and debug.
Create rich and connected apps
Android Studio knows not all code is written in Java, and not all code runs on the user's device.
C++ and NDK support
Android Studio fully supports editing C/C++ project files so you can quickly build JNI components in your app. The IDE provides syntax highlighting and refactoring for C/C++, and an LLDB-based debugger that lets you simultaneously debug your Java and C/C++ code. The build tools can also execute your CMake and ndk-build scripts without any modification and then add the shared objects to your APK.
Firebase and Cloud integration
The Firebase Assistant helps you connect your app to Firebase and add services such as Analytics, Authentication, Notifications and more with step-by-step procedures right inside Android Studio. Built-in tools for Google Cloud Platform also help you integrate your Android app with services such as Google Cloud Endpoints and project modules specially-designed for Google App Engine.
Eliminate tiresome tasks
Android Studio provides GUI tools that simplify the less interesting parts of app development.
When working with XML layout files, Android Studio provides a drag-and-drop visual editor that makes it easier than ever to create a new layout. The Layout Editor was built in unison with the ConstraintLayout API, so you can quickly build a layout that adapts to different screen sizes by dragging views into place and then adding layout constraints with just a few clicks.
You can use the APK Analyzer to easily inspect the contents of your APK. It reveals the size of each component so you can identify ways to reduce the overall APK size. It also lets you preview packaged assets, inspect the DEX files to troubleshoot multidex issues, and compare the differences between two APKs.
Vector Asset Studio
Android Studio makes it easy to create a new image asset for every density size. With Vector Asset Studio, you can select from Google-provided material design icons or import an SVG or PSD file. Vector Asset Studio can also generate bitmap files for each screen density to support older versions of Android that don't support the Android vector drawable format.
The Translations Editor gives you a single view of your translated resources, making it easy to change or add translations and find missing translations without opening each version of the strings.xml file. It even provides a link to order translation services.
