You exception has nothing to do with CascadeClassifier.

It might be possible to convert from different xml format, but most probably there are no any ready-to-use converters. And I don't think that you will succeed with LBP for body detection. LBP works on well textured objects which body is not.

There are already two more in OpenCV repository - lbpcascade_profileface.xml and lbpcascade_silverware.xml.

OpenCV 2.4.2 was released before NDK r8b. So there is no surprise that it does not compile.

You either can build OpenCV 2.4.2 with NDK r8 or fetch OpenCV master from repository and continue with NDK r8b.

/proc/self/smaps does exist on Android. What device are you using?

while True:
    ret, img =

    result = processFrame(img)

    cv2.imshow('some', result)
    if 0xFF & cv2.waitKey(5) == 27:
