java.lang.exceptionininitializererror

Hi foolks, I am new here in this form and new in OpenCV. I am making a project of eyes detection followed by http://romanhosek.cz/android-eye-detection-and-tracking-with-opencv/ tutorial. But at the end I got logcat wrror java.lang.exceptionininitializererror
Please help.... Thanks in Advance. . .
