Card emulation changes in Android 2.3.4

Posted on May 19, 2011 - By

Android 2.3.4 Gingerbread is the latest officially released platform that was rolled out a couple of weeks ago to the Google Nexus S and Nexus One. The biggest feature upgrade is that video chat is now available on Google Talk for all those whose devices with a front-facing camera. This new update is a maintenance release that adds several bug fixes and patches to the Android 2.3 platform and it does not increment the API level, it uses the same API level 10 as 2.3.3

Since the source code for 2.3.4 has already been pushed to the Android Open Source Project (AOSP), we’ve been analyzing it and we found the some changes in the NFC Java Classes, mainly in card emulation features: Read More

The new tag dispatch process in Android 2.3.3

Posted on Mar 01, 2011 - By

One of the new features in the Android framework API 2.3.3 is the improved support for NFC to interact with tags in a more friendly way. This changes include a new tag dispatch process, so, probably your NFC applications written for previous api levels now will fail. This is because these older versions used a single-step intent dispatch to notify interested applications that a tag was discovered. From 2.3.3 version (Api level 10), the platform uses a four-step process that enables the foreground application to take control of a tag event before it is passed to any other applications. This new process is designed to dispatch a tag to the correct activity without showing to the user the activity chooser dialog. Read More

NFC Tagwriter App

Posted on Feb 18, 2011 - By

As you may know, Google is pushing in the coming days an OTA update that adds read and write public APIs for the NFC chip. Well today, NXP launched  NFC Tagwriter, a free app for Android 2.3.3 using those features. This app allows to store contacts, URLs and text messages on any NFC tag


It only installs on devices with at least 2.3.3 version and NFC. Check it out

New NFC features in Android

Posted on Feb 09, 2011 - By

Well, there are good news: Google announced an update to Android 2.3 that adds new NFC capabilities for developers. This update is a small feature release but finally adds read and write APIs for the near field communications chip. Other updates include new APIs for Bluetooth, graphics, media framework, and speech recognition. The new version is available as a downloadable component for the Android SDK.
Now, the plataform provides a new set of APIs supporting a wider range of standard tags, including:

  • NFC-A (ISO 14443-3A)
  • NFC-B (ISO 14443-3B)
  • NFC-F (JIS 6319-4)
  • NFC-V (ISO 15693)
  • ISO-DEP (ISO 14443-4)
  • Mifare Classic
  • Mifare Ultralight
  • NFC Forum NDEF tags

This release also provides a limited peer-to-peer communication protocol and API. As they say “advanced tag dispatching now gives applications more control over how and when they are launched, when an NFC tag is discovered. Previously, the platform used a single-step intent dispatch to notify interested applications that a tag was discovered. The platform now uses a four-step process that enables the foreground application to take control of a tag event before it is passed to any other applications (android.nfc.NfcAdapter.enableForegroundDispatch()). The new dispatch process also lets apps listen for specific tag content and tag technologies, based on two new intent actions — android.nfc.action.NDEF_DISCOVERED and android.nfc.action.TECH_DISCOVERED”.
We are going to test this new functionality, will be sharing our views about it and posting some new examples.

Writing tags with Nexus S

Posted on Jan 14, 2011 - By

As said by Google CEO Eric Schmidt two month ago, the operating system Android 2.3  includes support for near field communication. But, at least in terms of the API and the sample code they supply, this version only includes tag reading capability. However, the  PN544 NFC chip inside the Nexus S supports read and write operations so, at the hardware level, all the functionality you need to support a full range of NFC services is in the handset. At the software level, there will be updates to the SDK rolled out on a phased basis that will enable developers to write NFC applications for mobile payments, p2p and other applications on Android Gingerbread devices.

NFC antenna and chip in Nexus S

Posted on Jan 05, 2011 - By

At Gibraltar SF we’ve been investigating NFC technology for the last couple of years, basically focusing in use cases, software / hardware implementation and security aspects. One of the main problems we had was the lack of commercial mobile phones with NFC capabilities. So, we’ve been programing NFC using the Series 40 Nokia 6212 NFC SDK simulator with external tag readers. I mean, although they were some developer version phones with NFC like Nokia’s 6212/6131 or even the Samsung’s s5230 used in the Sitges pilot, they weren’t available for the final user, so the projects turn into pilots and not into a real solution platform. But things are starting to change. Read More
