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. . .

how should we know without your code and a stacktrace ?
Actully I have many classis. . . .which class me have to share with you....
By the way I shared a link in my question I am following all that coding....
you're supposed to come up with a minimal testcase, that shows the error, and the resp. stacktrace.
no, we don't want all of your classes. but a link to an external blog isn't helpful either. (see it worked for that person, but not for you, so your situation is different already.)
read the FAQ, please.
Ok check I have edited my post and send my main Activity
far too much. anyway, the exact exception is still missing.
(btw, why did you comment System.loadLibrary("detection_based_tracker"); ? )
If I unComment that line then I got error Find library return null. . . why is it so?
i'm giving up.
no need to. nice that you got it solved ;)
I just got the problem but I am fail how to resolve it? I need your help because this is mine first project on OpenCV. . . I send you my code please give me the way to PM you. . . .
