Question

EDIT: I found the solution, see below

My first post on StackOverFlow. However I have been reading about this problem for a while without a solution that works.

What I would like to do is register the following Intent: android.nfc.action.TAG_DISCOVERED

I am doing the following in my Code:

    IntentFilter filter = new IntentFilter();
    filter.addAction("android.nfc.action.TAG_DISCOVERED");
    filter.addCategory("android.intent.category.DEFAULT");
    Log.d(TAG, "Created the new filter");
    reciever = new NFCBroadcastReciever(this);
    Log.d(TAG, "Created the new Broadcast Reciever");
    this.registerReceiver(reciever, filter);
    Log.d(TAG, "Registered new reciever");

The BroadCastReciever is defined as follows:

public class NFCBroadcastReciever extends BroadcastReceiver {

private Screen screen;
public static String TAG = "NFCBroadcastReciever";

NFCBroadcastReciever(Screen _screen){
    screen = _screen;
}

@Override
public void onReceive(Context context, Intent intent) {

    String action = intent.getAction();
    Log.d(TAG, "Action recieved: "+action);
    if(action != null && NfcAdapter.ACTION_TAG_DISCOVERED.equals(action)){
        paymentScreen.onNewIntent(intent);
    }
}

}

However I get an exception that the intent being fired from a tag read has no corresponding Activity. I would like to be able to only start listening for NFC events at a certain point in my application.

Thanks in advance for your help.

I found the solution to the problem actually, the key to getting NFC events to occur only on a specific activity while it is active and not when other activities are running. The sample in the Android SDK explains it: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/nfc/ForegroundDispatch.html
