FirebaseDatabaseにRxJava拡張機能を書いていますが、このコードを実行するたびにコメントでコードに示された行にstackOverflow例外が発生します。お願いして、ありがとうございました。FirebaseDatabaseのStackOverflow例外RxJava2の拡張
Flowable<Success> addDish(Dish dish, boolean upload) {
DatabaseReference newDishRef = databaseReference.push();
dish.setId(newDishRef.getKey());
return Flowable.create(
e -> newDishRef.setValue(dish) // StackOverFlow Exception here
.addOnSuccessListener(
aVoid -> e.onNext(upload ? new Success(dish.getMenuImage()) : new Success()))
.addOnCompleteListener(task -> e.onComplete()).addOnFailureListener(e::onError),
BackpressureStrategy.BUFFER);
}
