 * default, but change that order based on the address the user picked on previous requests.
 *
 * <p>The history is not persisted over reboots, and it's cleared every time the service
 * replies to a {@link #onFillRequest(FillRequest, CancellationSignal, FillCallback)} by calling
 * {@link FillCallback#onSuccess(FillResponse)} or {@link FillCallback#onFailure(CharSequence)}
 * (if the service doesn't call any of these methods, the history will clear out after some
 * pre-defined time). Hence, the service should call {@link #getFillEventHistory()} before
 * finishing the {@link FillCallback}.
