Start Android Development in 5 Minutes

Welcome to Android application development! If you’re new to Android app development, this where you should begin.

Download Android Studio

Android Studio is a new Android development environment based on IntelliJ IDEA. Similar to #Eclipse with the ADT Plugin, Android Studio provides integrated Android developer tools for development and debugging. On top of the capabilities you expect from IntelliJ, Android Studio offers:

  • Gradle-based build support.
  • Android-specific refactoring and quick fixes.
  • Lint tools to catch performance, usability, version compatibility and other problems.
  • ProGuard and app-signing capabilities.
  • Template-based wizards to create common Android designs and components.
  • A rich layout editor that allows you to drag-and-drop UI components, preview layouts on multiple screen configurations, and much more.
  • Built-in support for Google Cloud Platform, making it easy to integrate Google Cloud Messaging and App Engine as server-side components.


This download includes:

  • Android Studio early access preview
  • All the Android SDK Tools to design, test, debug, and profile your app
  • The latest Android platform to compile your app
  • The latest Android system image to run your app in the emulator

Now start Android studio
