Hi OpenCV team. I have added the OpenCV V2.4.5(for Android), and it is OK to compile the program. when the program pointer is on the line (Mat mat = new Mat()) and I click the button of Next step, the program pointer will enter the constructor of Mat in Mat.class. after leaving the constructor, the program pointer does not get back to the original function which calls the constructor of Mat. it enter the InvocationTargetException.class and show the message of Source not found. I have set the path of Mat.java file, but it does not work. do I miss some parameter settings for OpenCV?
