Several weeks ago we released Android 2.3, which introduced several new forms of communication for developers and users. One of those, Near Field Communications (NFC), let developers get started creating a new class of contactless, proximity-based applications for users.

NFC is an emerging technology that promises exciting new ways to use mobile devices, including ticketing, advertising, ratings, and even data exchange with other devices. We know there’s a strong interest to include these capabilities into many applications, so we’re happy to announce an update to Android 2.3 that adds new NFC capabilities for developers. Some of the features include:

A comprehensive NFC reader/writer API that lets apps read and write to almost any standard NFC tag in use today.

Advanced Intent dispatching that gives apps more control over how/when they are launched when an NFC tag comes into range.

Some limited support for peer-to-peer connection with other NFC devices.

We hope you’ll find these new capabilities useful and we’re looking forward to seeing the innovative apps that you will create using them.

Android 2.3.3 is a small feature release that includes a new API level, 10. Going forward, we expect most devices shipping with an Android 2.3 platform to run Android 2.3.3 (or later). For an overview of the API changes, see the Android 2.3.3 Version Notes. The Android 2.3.3 SDK platform for development and testing is available through the Android SDK Manager.
