Это ошибка, которую я получаю, я подумал, что проблема связана с плавающей кнопкой действия, но мой вопрос в том, почему? У меня есть зависимость для нее по умолчанию в приложении.

     implementation 'com.google.android.material:material:1.2.1'
 

Поэтому я не уверен, почему это не работает. Мое приложение предназначено для носимых устройств, может ли это быть проблемой?

В любом случае, вот моя активность и макет xml:
