В моем приложении есть три активации: 1-й — калькулятор BMI, 2-й — вызов больницы, подключенный к базе данных, 3-й — действие карты (которое сбой) всякий раз, когда я нажимаю на значок карты. И, пожалуйста, для всех, кто собирается ответить на мой вопрос, пожалуйста, обратите внимание на мое имя и обратите внимание, что я идиот в разработке, и я буквально ничего не знаю, поэтому, если вы дадите мне решение, я был бы признателен, если вы объясните мне, как новичку, спасибо.

мой код:
