android - How to use method onNewIntent(Intent intent) inside a Fragment?

I'm trying to use NFC Hardware from my device. But, the problem is that when I register the Activity to receive the Intent:

PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, getClass()).addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP), 0);

I receive the result in an Activity instead of a Fragment. Is there a way to handle this result inside a Fragment?

Thanks in advance!

onNewIntent belongs to Activity so you cannot have it in your fragment. What you can do is pass the data to your fragment when it arrives in onNewIntent provided you have the reference to the fragment.

Fragment fragment;  
@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);

    // Check if the fragment is an instance of the right fragment
    if (fragment instanceof MyNFCFragment) {
        MyNFCFragment my = (MyNFCFragment) fragment;
        // Pass intent or its data to the fragment's method
        my.processNFC(intent.getStringExtra());
    }

}
