    super.onActivityResult(requestCode, resultCode, data);

    // Pass on the activity result to the helper for handling
    // NOTE: handleActivityResult() will update the state of the helper,
    // allowing you to make further calls without having it exception on you
    if (billingHelper.handleActivityResult(requestCode, resultCode, data)) {
        Log.d(TAG, "onActivityResult handled by IABUtil.");
        handlePurchaseResult(requestCode, resultCode, data);
        return;
    }

    // What you would normally do
    // ...
}
