Meet Android Studio

Android Studio is the official Integrated Development Environment (IDE) for Android app development, based on IntelliJ IDEA . On top of IntelliJ's powerful code editor and developer tools, Android Studio offers even more features that enhance your productivity when building Android apps, such as:

A flexible Gradle-based build system
A fast and feature-rich emulator
A unified environment where you can develop for all Android devices
Apply Changes to push code and resource changes to your running app without restarting your app
Code templates and GitHub integration to help you build common app features and import sample code
Extensive testing tools and frameworks
Lint tools to catch performance, usability, version compatibility, and other problems
C++ and NDK support
Built-in support for Google Cloud Platform, making it easy to integrate Google Cloud Messaging and App Engine

This page provides an introduction to basic Android Studio features. For a summary of the latest changes, see Android Studio release notes.

Project structure

Figure 1. The project files in Android view.

Each project in Android Studio contains one or more modules with source code files and resource files. Types of modules include:

Android app modules
Library modules
Google App Engine modules

By default, Android Studio displays your project files in the Android project view, as shown in figure 1. This view is organized by modules to provide quick access to your project's key source files.

All the build files are visible at the top level under Gradle Scripts and each app module contains the following folders:

manifests: Contains the AndroidManifest.xml file.
java: Contains the Java source code files, including JUnit test code.
res: Contains all non-code resources, such as XML layouts, UI strings, and bitmap images.

The Android project structure on disk differs from this flattened representation. To see the actual file structure of the project, select Project from the Project dropdown (in figure 1, it's showing as Android).

You can also customize the view of the project files to focus on specific aspects of your app development. For example, selecting the Problems view of your project displays links to the source files containing any recognized coding and syntax errors, such as a missing XML element closing tag in a layout file.
