Разбор транзита Json с гугл карт в андроид

Question

Мне нужно получить информацию о транзите с карт Google. Приведенный ниже код извлекает информацию из фиктивного файла JSON, однако, когда я указываю URL карт Google для извлечения информации JSON, я не получаю никакого результата. Ниже приведен мой код. Я новичок в этом, любые материалы, касающиеся этого, будут очень полезны.

}

Мне нужна помощь в разборе этих деталей. Какие изменения я должен внести в мой код Java?
