Working with Loader and ResultReceiver - how to fix the error?

Question

Android

There is an activity and a service that receives data via REST.
Activity implements LoaderManager.LoaderCallbacks and MyResultReceiver.Receiver (worse than the usual approach).
There is a problem when turning the device, you need to save the current receiver, I do this:

if (savedInstanceState != null) {
  _receiver = savedInstanceState.getParcelable(Extra.RECEIVER);
} else {
  _receiver = new MyResultReceiver(new Handler());
}
_receiver.setReceiver(this);

It works, but if the activity was unavailable for a long time, I get an error when casting, i.e. with savedInstanceState the base ResultReceiver comes, and not my MyResultReceiver.
Looking for a solution.
