org.xmlpull.v1.XmlPullParserException: ожидаемая строка в кавычках Ошибка

Question

Попытка прочитать URL с использованием входного потока. Сам код предназначен для создания списка подкастов из RSS-канала. понятия не имею, почему ошибка продолжает появляться. Попытался напрямую вставить RSS, но это ничего не изменило.

Код:

Я перепробовал практически все, что мог придумать. В верхней части следующих нескольких уроков, чтобы сделать это. Если это поможет, перед добавлением метода Async я сделал то же самое, читая из папки ресурсов, и это работало отлично. Только когда я переключился на чтение xml динамически, я начал получать сообщения об ошибках.
