Google has confirmed a delay to the public release of Android 3.0 Honeycomb, saying that the source code is not ready.
In a statement released to V3.co.uk, Google said that more work needs to be done to the Honeycomb platform before it is made available to a wider audience.
"Android 3.0 Honeycomb was designed from the ground up for devices with larger screen sizes, and improves on Android favourites such as widgets, multi-tasking, browsing, notifications and customisation," a Google spokesperson said.
"While we're excited to offer these new features to Android tablets, we have more work to do before we can deliver them to other device types including phones."
Google added that it remains committed to providing Android as an open platform across many device types, and "will publish the source as soon as it's ready".
The decision to delay the release seems odd given that the Motorola Xoom runs a fully-functioning version of the operating system and has been available to buy in the US since 24 February. The Xoom is due to be launched in the UK in April.
Google's decision is unlikely to affect device manufacturers, including Asus, Acer and Samsung, which are all gearing up to launch Honeycomb tablets in the coming weeks.
Meanwhile, Google has announced that it will launch in-application billing for the Android platform next week.
"In preparation for the launch, we are opening up Android Market for upload and end-to-end testing of your apps that use in-app billing," Google said in the Android Developer Blog.
"You can now upload your apps to the Developer Console, create a catalogue of in-app products, and set prices for them," the firm said.
"During these test transactions, the in-app billing service interacts with your app exactly as it will for actual users and live transactions."
