Я пытаюсь реализовать приложение, где, когда пользователь нажимает кнопку, отображается карта. Я сделал другое приложение, использующее только карту в качестве основного действия, и оно отлично работает. Но если я использую тот же код, что и другое действие, и пытаюсь вызвать его с помощью кнопки, приложение останавливается и никакая ошибка не отображается. Я не уверен, является ли ошибка кодом карты или намерением.Как мне называть карты Google с помощью кнопки?
