Answer 1

Убедитесь, что вы используете правильную (последнюю) версию библиотеки поддержки v4. У меня была такая же ошибка, пока я не понял, что использую более старую библиотеку поддержки v4 (в которой отсутствует этот метод API 18).

Answer 2

Это означает, что вы вызываете метод getLayoutMode в устройстве ниже API 18 и этот метод был добавлен только в API 18, как вы можете видеть в documentation.
