At the core of Android Studio is an intelligent code editor capable of advanced code completion, refactoring, and code analysis.
The powerful code editor helps you be a more productive Android app developer.
Code templates and GitHub integration
New project wizards make it easier than ever to start a new project.
Start projects using template code for patterns such as navigation drawer and view pagers, and even import Google code samples from GitHub.
Multi-screen app development
Build apps for Android phones, tablets, Android Wear, Android TV, Android Auto and Google Glass.
With the new Android Project View and module support in Android Studio, it’s easier to manage app projects and resources.
Virtual devices for all shapes and sizes
Android Studio comes pre-configured with an optimized emulator image.
The updated and streamlined Virtual Device Manager provides pre-defined device profiles for common Android devices.
Android builds evolved, with Gradle
Create multiple APKs for your Android app with different features using the same project.
Manage app dependencies with Maven.
Build APKs from Android Studio or the command line.
More about Android Studio
For more details about features available in Android Studio, read the overview at Android Studio.
If you have been using Eclipse with ADT, be aware that Android Studio is now the official IDE for Android, so you should migrate to Android Studio to receive all the latest IDE updates. For help moving projects, see Migrating to Android Studio.

SDK Platforms Release Notes
See Also
This document provides release information about the SDK Platform packages required for app development. If you want details about the features and APIs added in each Android version, instead read the highlights in the About section.
In order to compile your application against a particular version of Android, you must use the SDK Manager to download and install the SDK Platform for that release. If you want to test your application on an emulator, you must also download at least one System Image for that Android version.
Each platform release includes system images that support a specific processor architecture, such as ARM EABI, Intel x86 or MIPS. Platform releases also include a system image that contains Google APIs. The SDK Manager lists available platform system images under each platform version header, for example:
- ARM EABI v7a System Image
- Intel x86 Atom System Image
- MIPS System Image
- Google APIs
To determine what revisions of an Android platform you have installed, refer to the Packages listing in the Android SDK Manager.
Important: To download the most recent Android system components from the Android SDK Manager, you must first update the SDK Tools to the most recent release and restart the SDK Manager. If you do not, the latest Android system packages may not be available for download.

Android 4.0
Android 4.0, Revision 2 (December 2011)
Maintenance update. The system version is 4.0.2.
Dependencies: SDK Tools r14 or higher is required.
Android 4.0, Revision 1 (October 2011)
Initial release. The system version is 4.0.1.
Dependencies: SDK Tools r14 or higher is required.
Emulator Skins
The downloadable platform includes the following emulator skins:
- QVGA (240×320, low density, small screen)
- WQVGA400 (240×400, low density, normal screen)
- WQVGA432 (240×432, low density, normal screen)

- WSVGA (1024×600, medium density, large screen) new
- WXGA (1280×800, medium density, xlarge screen)
To test your application on an emulator that represents the latest Android device, you can create an AVD with the new WXGA720 skin (it’s an xhdpi, normal screen device). Note that the emulator currently doesn’t support the new on-screen navigation bar for devices without hardware navigation buttons, so when using this skin, you must use keyboard keys Home for the Home button, ESC for the Back button, and F2 or Page-up for the Menu button.
However, due to performance issues in the emulator when running high-resolution screens such as the one for the WXGA720 skin, we recommend that you primarily use the traditional WVGA800 skin (hdpi, normal screen) to test your application.
