The toolchain wraps your Chrome App with a native application shell and enables you to distribute your app via Google Play and the Apple App Store. We provide a simple developer workflow for packaging a Chrome App natively for mobile platforms. You can run your Chrome App on a device or emulator using the command-line or an IDE. Alternatively, you can use the Chrome Apps Developer Tool to run your app on an Android device without the need to install an IDE or the mobile platform’s SDK.
Google suggests developers interested in learning more check out the dev workflow and sample apps and it will be taking feedback through Stack Overflow, the G+ Developers page, and its developer forum.
