Prevent alert tone when scanning / identifying an NFC intent

Question

Perhaps I'm missing something but when I scan an NFC tag via a galaxy nexus, the phone always makes the default alert tone.

Is there a way of programmatically switching this off ? I have scoured the menus / preferences and can't find a way of doing this. The next step ... ICS source code :-/

You'll probably have better luck with this question on http://android.stackexchange.com. This of course assumes you haven't rooted your phone. — Marvin Pinto, Jan 05 '12 at 14:19
Heh.. android.stackexchange.com said "go to stackoverflow.com"... Good job I can spot a recursion. Phone not rooted as I want to put this into the app for non-rooted phones... — Richard Green, Jan 05 '12 at 15:11
What I was trying to get at was: If this option to turn off the tone really doesn't exist within the _regular_ settings (and you verified this on android.stackexchange.com), then there's a very good chance you won't be able to do it programatically. The rooted phone comment applies to the latter. — Marvin Pinto, Jan 05 '12 at 15:23
FWIW. I have raised this on the android code base feature request list : http://code.google.com/p/android/issues/detail?id=24022 — Richard Green, Jan 06 '12 at 12:00

with android-19 you can:

as described in: http://developer.android.com/reference/android/nfc/NfcAdapter.html#FLAG_READER_NO_PLATFORM_SOUNDS

By using NfcAdapter.enableReaderMode() and the flag FLAG_READER_NO_PLATFORM_SOUNDS instead of NfcAdapter.enableForegroundDispatch()

Here is a simple example of how to silence/change nfc sounds

public class MainActivity extends Activity implements ReaderCallback{
private NfcAdapter mNfcAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mNfcAdapter = NfcAdapter.getDefaultAdapter(this);
}

@Override
public void onResume() {
    super.onResume();
    // This example works using using simple mifare ultralight tags. Set any necessary flags for other tags 
    mNfcAdapter.enableReaderMode(this, this, NfcAdapter.FLAG_READER_NFC_A | NfcAdapter.FLAG_READER_NO_PLATFORM_SOUNDS, null);
}

@Override
public void onPause() {
    super.onPause();
    mNfcAdapter.disableReaderMode(this);
}

@Override
public void onTagDiscovered(Tag tag) {
    // Play your own sound here

    // Then handle your tag
}

}

There isn't a way to pro grammatically turn this sound off or to override the Touch to Beam UI.
