"return 0 faces because error exists btk_facefinder_putdcr" Error in Android face detector

Question

fd = new FaceDetector(mFaceWidth, mFaceHeight, MAX_FACES);
count = fd.findFaces(mFaceBitmap, faces);

Using the above code I'm getting this error on some images.

return 0 faces because error exists btk_facefinder_putdcr

Can someone help me? How to get rid of this?

The same code works fine for some other images.

Bitmap srcImg = BitmapFactory.decodeFile(imgUrl);
    Bitmap srcFace = srcImg.copy(Bitmap.Config.RGB_565, true);
    srcImg = null;
    int w = srcFace.getWidth();
    int h = srcFace.getHeight();
    if (w % 2 == 1) {
        w++;
        srcFace = Bitmap.createScaledBitmap(srcFace,
                srcFace.getWidth()+1, srcFace.getHeight(), false);
    }
    if (h % 2 == 1) {
        h++;
        srcFace = Bitmap.createScaledBitmap(srcFace,
                srcFace.getWidth(), srcFace.getHeight()+1, false);
    }
