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. . .

Actully I have many classis. . . .which class me have to share with you....

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

Nabeel Ahmed gravatar imageNabeel Ahmed ( 2014-05-14 08:51:10 -0600 )edit

far too much. anyway, the exact exception is still missing.

(btw, why did you comment System.loadLibrary("detection_based_tracker"); ? )

berak gravatar imageberak ( 2014-05-14 08:56:49 -0600 )edit

If I unComment that line then I got error Find library return null. . . why is it so?

Nabeel Ahmed gravatar imageNabeel Ahmed ( 2014-05-15 05:15:10 -0600 )edit

berak gravatar imageberak ( 2014-05-15 08:13:22 -0600 )edit

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. . . .
