According to https://forums.bignerdranch.com/t/challenge-saving-state-notserializableexception-error/8018/5 you should implement or extend some class from Parcelable. In my case I had a DialogFragment with an interface MyCallback extending Serializable. In newInstance(MyCallback callback) builder I used:

Bundle args = new Bundle();
args.putSerializable(key, callback);

that led to an exception. Then I rewrote MyCallback to extend Parcelable and also added some methods to a callback when invoked this DialogFragment. At least, it doesn't crash on Home button or screen off.

Also changed to:

Bundle args = new Bundle();
args.putParcelable(key, callback);
