Android 2.3.3 is now available for the Android SDK. This update adds new NFC capabilities for developers, such as the ability to write to tags and create peer-to-peer connections.
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.
