我已经成功编译了opencv测试示例（videoemulation），但是在模拟器上运行它给了我一个奇怪的错误：
06-25 15:36:34.526: D/dalvikvm(621): Trying to load lib /data/data/org.siprop.opencv /lib/libopencv.so 0x405139b0

06-25 15:36:34.637: D/VideoEmulation(621): Failed to initialize face detection!
是不是我没有加载功能。请指导我。
这是 OpenCV Java 文件：
public class OpenCV {
static {
System.loadLibrary("opencv");
}
public native byte[] findContours(int[] data, int w, int h);
public native boolean createSocketCapture(String address, String port, int width, int height);
public native void releaseSocketCapture();
public native boolean grabSourceImageFromCapture();
public native byte[] getSourceImage();
public native boolean setSourceImage(int[] data, int w, int h);
public native boolean initFaceDetection(String cascadePath);
public native void releaseFaceDetection();
public native boolean highlightFaces();
public native Rect[] findAllFaces();
public native Rect findSingleFace();
}
