我正在尝试在我的项目中使用javacv库。我在libs文件夹中导入了javacpp.jar和javacv.jar。但是当我尝试根据以下代码将haarcascade_frontalface_alt.xml从raw文件夹加载到CvHaarClassifierCascade时
CvHaarClassifierCascade cascade = new CvHaarClassifierCascade(cvLoad("android.resource:// com.era.facerecognitionandcropping/raw/haarcascade_frontalface_alt"));
抛出以下异常。
