Oh, One more thing, if i replace "haarcascade_frontalface_alt" with the 
"haarcascade_lefteye_2splits.xml", and rename it to 
"haarcascade_frontalface_alt". it's work in 10-15cm between eye and the 
device's camera. I am using Samsung Galaxy i9003.
Please give me a help! My thesis's deadline is coming.

You need to give them two different /temporary/ filenames as well. Something 
like
    File classifierFileEye = Loader.extractResource(getClass(), "haarcascade_lefteye_2splits.xml", 
            context.getCacheDir(), "classifier2", ".xml");
should work..

HI, Mr.Samuel i have tried like this (file above) and i call the 
cvHaarDetectObjects:

 faces = cvHaarDetectObjects(grayImage, classifier_face, storage_face, 1.1, 3, CV_HAAR_DO_CANNY_PRUNING);
 eyes = cvHaarDetectObjects(grayImage, classifier_eye, storage_eye, 1.1, 3, CV_HAAR_DO_CANNY_PRUNING);
 BUt it isn't work. It doesn't error when i load xml file. But i shown " Force Close", you know, it's work when i run only Haar_face, I really don't know the reason.
Please take a look over my code!
