02.09.2018, 15:35. Показов 1376. Ответов 3
Пишу новостное приложение. Прога начинается с navigation drawer activity, в которое я запарсил через xml api новостей.
Прога еще имеет 2 фрагмента в шторке навигации.
Как только запускаю приложение - оно сразу крашится. Studio не подсвечивает ошибок в коде... прошу помощи! Дедлайн близко, а это мое тестовое на Juniora((
Вот код MainActivity
