OpenCV的錯誤在android系統

Question

我已經successully編譯，但是對模擬器中運行它給我奇怪的錯誤OpenCV的測試例（videoemulation）：

06-25 15:36:34.526: D/dalvikvm(621): Trying to load lib /data/data/org.siprop.opencv /lib/libopencv.so 0x405139b0 
06-25 15:36:34.566: D/dalvikvm(621): Added shared lib /data/data/org.siprop.opencv/lib/libopencv.so 0x405139b0 
06-25 15:36:34.566: D/dalvikvm(621): No JNI_OnLoad found in /data/data/org.siprop.opencv/lib/libopencv.so 0x405139b0, skipping init 
06-25 15:36:34.619: D/VideoEmulation(621): mOpenCVAction = TRACK_SINGLE_FACE 
06-25 15:36:34.627: D/VideoEmulation(621): onResume 
06-25 15:36:34.627: D/VideoEmulation(621): initFaceDetect 
06-25 15:36:34.637: E/CVJNI(621): Error loading cascade. 
06-25 15:36:34.637: D/VideoEmulation(621): Failed to initialize face detection! 

難道我不是加載的功能。請指導我。

這是OpenCV的的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(); 

}

確保所有機（C++）功能塊：

extern "C" { 
... 
}
