Комната постоянства библиотека вылетает проблема на Android 4.4 KitKat

Я работаю с проектом, который использует библиотеку персистентности комнаты версии 1.1.1, она работает нормально на всех устройствах, которые находятся выше Android 4.4 (например: Lollipop, Marshmallow и т. Д.).но он падает на Android версии 4.4 всякий раз, когда я пытаюсь установить приложение.я приложил журнал аварий и другие связанные файлы.

Журнал ошибок:

Добавьте это до инициализации экземпляра комнаты bd. 

MultiDex.install(this)
...
