Google Toolset Allows Chrome Apps on Android, iOS

A developer preview of a tool to adapt Chrome browser apps for Android and iOS devices was released Tuesday by Google. The move extends the reach of a new kind of browser app that can also work outside the browser.

In September, the company introduced Chrome Apps, which it said combined the advantages of the Web with those of locally installed software.

They can utilize built-in sandboxing for security, and can connect to the cloud, be automatically updated or sync with any desktop device.

Examples of the Chrome Apps include Pixir Touch Up for modifying photos, the Wunderlist to-do list and Cracking Sands racing game.

Mozilla notes that Open Web Apps are the same as standard Web sites or Web pages, except that they can be installed on a device, work offline, and have access to device APIs for interacting with cameras, address books and other on-device capabilities.

Google has released in developer preview a toolchain software tool that enables Chrome Apps to run on Android and iOS devices, through the use of the open-source Apache Cordova mobile framework. Cordova is used to build native mobile apps with HTML, CSS and JavaScript.

The toolchain, Google said Tuesday on its Chromium Blog, "wraps your Chrome App with a native application shell," thus allowing it to be distributed through the Google Play marketplace or the Apple App Store. Chrome APIs are accessible to the Chrome Apps, including OAuth2 sign-in, message pushing, sockets for sending and receiving data over TCP and UDP, and alarms for running scheduled tasks.
