The Android Developers Guide now has a new section dedicated to near field communication technology.

The updated guide gives developers looking to create NFC applications an overview of the technology and the API plus details on:

• Declaring Android Manifest elements.
• The tag dispatch system.
• NDEF messages.
• Reading an NFC tag.
• Writing to an NFC tag.
• Peer-to-peer data exchange.

The addition of this new section in the guide follows the release of Android 2.3.3 last month. This introduced:

• 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.
