Обнаружение лиц на изображениях с использованием JavaCV для Android

Я делаю приложение для обнаружения лиц (не в режиме реального времени) для обнаружения лиц на изображении на Android. Я пытался использовать класс FaceDetector в android.media, что хорошо, но не очень точно. поэтому я загрузил пакеты JavaCV и java.cpp (с OpenCV v 2.3). Проект работает, но дает исключения:

просто не знаю в чем проблема помогите пожалуйста
