Sending URL via NFC to be opened by browser

Question

I want to be able to send a URL via NFC so that it can be opened by the receiving phone's browser on android phones. Is this a possible action?

Answer 1

After scratching my head for a few hours and browsing numerous posts. I found that all I needed to do was implement the NdefCallbacks and set the uri in the "createNdefMessage" method.

First implement the NdefCallbacks

public class MyActivity implements CreateNdefMessageCallback, OnNdefPushCompleteCallback {

Add the unimplemented methods

@Override
public NdefMessage createNdefMessage(NfcEvent event) {  
    ...
}
...
@Override
public void onNdefPushComplete(NfcEvent arg0) {
    ...
}

Create an NFC Adapter at the top of your activity

NfcAdapter mNfcAdapter;

Then setup the NFC Adapter in the onCreate method

mNfcAdapter = NfcAdapter.getDefaultAdapter(this);
if(mNfcAdapter != null) {
    // Register callback to set NDEF message
    mNfcAdapter.setNdefPushMessageCallback(this, this);

    // Register callback to listen for message-sent success
    mNfcAdapter.setOnNdefPushCompleteCallback(this, this);
} else {
    Log.i("LinkDetails", "NFC is not available on this device");
}

Then put the following in your createNdefMessage method:

return new NdefMessage(new NdefRecord[] {
    NdefRecord.createUri(YOUR_URL_HERE)
});

Tap away, Android will handle the rest.

Thanks to the fine folks at TAPPED for their guide, which got me about 3/4ths of the way to a successful NFC implementation.

Answer 2

Heck yes.

Put an NDEF formatted record containing the URL of the website onto the tag and you're done.

The Android SDK is FULL of examples.
