Google published more details of technology to allow Android developers to build applications for its Google TV platform, an open development platform for combining apps and web access with live TV.

The company announced that Android Market would be coming to Google TV via an add-on for the Android SDK, and the technology is due to be released in line with the upcoming update of the Honeycomb version of Android.

The add-on will allow developers to build apps for Google TV using the standard tools in the Android SDK, with the addition of a Google TV emulator. It will also provide APIs for interacting with Google TV data, such as channel information.

“That means developers can build great new Android apps for TV, optimise existing mobile or tablet apps for TV, and distribute those apps through Android Market,” Google TV product manager Ambarish Kenghe wrote on the Android developers’ blog.

Although it won’t be as feature-rich as the full version of Google TV, the add-on can emulate the platform for developers using Linux with KVM. Other OSes will be supported in due course.

Developers will also be able to test existing Android apps to find out whether they need to be tweaked to work on for Google TV. To help with compatibility, Google is publishing user interface guidelines so developers know how apps need to differ from those targetting other Android devices.

“These are still early days for Google TV, and this release is another step in providing developer tools for the big screen. While the number of apps available on TV will initially be small, we expect that through this early release of the add-on you'll be able to bring optimized TV apps into the ecosystem more quickly,” Kenghe added.
