Gradle-based flexible build system
Fast and feature-rich emulator
Unified environment to develop for all Android devices
Instant Run, which pushes changes to a running app without building a new APK
Code templates and GitHub integration to help you build common app functionality and import sample code
Rich testing tools and frameworks
Lint tool to catch performance, usability, version compatibility, and other issues
C++ and NDK support
Built-in support for Google Cloud Platform for easy integration with Google Cloud Messaging and App Engine
