Android Studio 3.0 Canary 1, SDK Updates, and http://maven.google.com are now available

Wednesday, May 17, 2017Today we have lots of updates to share with you including Android Studio 3.0 Canary 1, SDK updates, new library updates through maven.google.com, and additional Android O support.

Android Studio 3.0 Canary 1

This canary and dev channel release encapsulates our previous work in Android Studio 2.4, but mergers with our Gradle 2.5 plugin using Gradle 4.0 milestone 1. Given the magnitude of this update: new features, Kotlin language support, and breaking Gradle changes, we have decided to promote the version to Android Studio 3.0.

The Android Gradle plugin 3.0.0-alpha1 aims to improve build performance for Android projects with a large number of modules. In order to bring about these gains, there are some breaking changes in the plugin behavior, DSL, and APIs. This impacts both build files and Gradle plugins. For instructions on how to migrate your own project to use this plugin, see Migrate to the 3.0 Plugin.

Unfortunately we are not able to offer patches to Android Studio 3.0 from Android Studio 2.4 Preview 7 or any previous version. We will continue to offer patch upgrades as new canaries are released from Android Studio 3.0, but can not offer patches to this version. We will not update Android Studio 2.4 versions any further.

For much more information, see the Android Studio 3.0 announcement.

Googles Maven repository for Android libraries

The Android Support Library dependencies are now available from Googles Maven repository at http://maven.google.com—instead of downloading from the Android SDK Manager.

This new distribution method simplifies Maven dependency management for those using continuous integration systems.

Two new libraries available today are: Architecture Components Library, Android Instant App Library, and we have updated Support Library to 26.0.0-beta1*.

In the future we plan to distribute all Android libraries only through maven.google.com.

From now on, the latest versions of the following libraries are available only from Googles Maven repo (new versions are not available in the SDK Manager):

• Android Support Library
• Constraint Layout Library
• Android Test Support Library
• Databinding Library

To start using Googles Maven repository, follow these instructions to update your build dependencies.
