Приложение вылетает при использовании AsyncTask<> Android

Пишу приложение на Android Studio конвертер валют, но столкнулся с проблемой. Приложение вылетает при нажатии на кнопку "рассчитать". Приложение парсит текущий курс с цб и конвертирует значение в доллары и евро. Не могли бы вы подсказать, что не так? Android Studio варнинги не показывает...
