Угадаю с ходу, тк видел такую ошибку. Проблема в использовании ActionBar'a из support библиотеки.

Об этом написано в документации: developer.android.com/reference/android/support/v7...


When using the support library, you can add the action bar to the top of your activity window by extending the ActionBarActivity class and setting the activity theme to Theme.AppCompat or a similar theme.


Соответственно вам нужно сделать так
<style name="Theme.Example" parent="@Theme.AppCompat ">


+ там еще пару тем с вариациями дарк/лайт
