Hi,
I am writing an NFC application on Gingerbread 2.3.3. The application
writes and reads data to and from tags. I am using the white plastic tags
that look like a badge.
I have been able to write data to the tags. However, it only works when the
tag is unformatted. That is, I get a brand new ta
Hi Manuel,
You can write to a formatted card using the Ndef technology class (as long
as it was not made read-only).

Hi all, I have the same issue. I write the tag by Ndef class, but the tag
can't be read by any readers application, it cause them crash.
The source code is below:
...
Tag tagFromIntent = null;
void writeTag(){
NdefRecord record = new NdefRecord(NdefRecord.TNF_WELL_KNOWN,
NdefRecor
hi all, the exception is due to the intent action, it is
NfcAdapter.ACTION_NDEF_DISCOVERED, not ACTION_TAG_DISCOVERED, which is
listened by tag or tagwriter app.

Hallo,
Well, the field in the constructor is clearly named "payload", so in
NDEF terminology it has to contain the complete payload. Text records
(and other RTDs) are built on top of the NDEF specification, so in my
opinion, a higher layer of abstraction (like a class NdefTextRecord),
that sets up
I'm no NFC guru, but from what I can tell of the docs and the samples,
there's no way to do card emulation on an Android device at this time,
using the SDK. Is that correct?
I see the published classes/methods for reading/writing tags, and for
the Ndef push using P2P and the mysterious com.android
Hi Dave,
Correct, we do not support Card Emulation in the SDK. It's actually very
hard to do this in a consistent way across the Android platform, due to the
current hardware architecture of NFC. Different NFC hardware can
support Card Emulation in very different ways, to the point where its very
