Amazon unveiled an updated version of the Fire OS which powers its Kindle Fire tablets, noting that it enables Android developers to offer their apps “with little or no work” while taking advantage of the retail giant’s monetisation features.

This includes support for its Whispersync for Games cross-device synchronisation service, GameCircle social network, in-app purchasing, and Mobile Associates ecommerce API.

According to the company, Fire OS 3.0 (“Mojito”) is built on Android 4.2.2, and “75 per cent of the tablet apps that run on Android also run on Fire OS, with no additional development work”. It also supports HTML5 apps.

Amazon also noted that it has made a number of low-level platform enhancements.

This includes an “optimising download manager” which enables parallel content downloads while not impacting foreground app performance; a new graphics pipeline which is customised to quickly load large images; improved touch responsiveness; and a reading mode which boosts battery life by powering-down unnecessary system components.

Fire OS 3.0 is used “exclusively” by the new Kindle Fire HD and Kindle Fire HDX tablets.
