Я новичок в android и тестирую свои навыки в различных тестовых приложениях. Теперь я пытаюсь получить данные с URL-адреса Json и создать из списка любимых объектов Json. Gradle завершается без каких-либо проблем, но каждый раз, когда начинается мое приложение, он падает с следующей ошибкой:java.util.ArrayList нельзя отнести к
попытки вызвать метод интерфейса «INT java.util.List.size()» на нулевой ссылке на объект
я использовал в качестве учебника следующих ресурсов:
общедоступных префов: http://androidopentutorials.com/android-how-to-store-list-of-values-in-sharedpreferences/
для Json парсера: http://www.androidhive.info/2014/09/android-json-parsing-using-volley/
Это моя ошибка код и активности где ошибка:
