Don't you forget to add the same code lines for your cascade file as the following ones:

 InputStream is = context.getResources().openRawResource(R.raw.haarcascade_profileface);
 FileOutputStream os = new FileOutputStream(mCascadeFile);

 byte[] buffer = new byte[4096];

 int bytesRead;

 while ((bytesRead = is.read(buffer)) != -1) {

     os.write(buffer, 0, bytesRead);

}

is.close();

os.close();

This code reads the cascade XML from resources and saves it as a file.

In the sample it's done for the face cascade, so you need to do it for the eye cascade as well.

Then, when you find a face rectangle you can use the 2nd cascade to find eyes inside it.

Hi, I tried some methods for eye detection (template matching, diff matrix + contours, eyemap) and get good result with - get face from lbp casscade (faster than haar) extract area where eyes should be, detect eyes in this area via haar casscade for eye and use this image as actual template for template matching.

I will put some samples on my blog soon.
