Hey guys, i've migrated my project to a new computer, and it stopped working. I get NoClassDefFoundError: org.opencv.objdetect.CascadeClassifier when trying to run it.

I'm using eclipse indigo, on win7, trying to run on andorid 2.3.3. everything worked well before!

i have the opencv2.4.2.jar referenced in my project, (no _src dirs) and i can see the CascadeClassifier.class there.. i don't know what's wrong..

any ideas?

Have you references the 'OpenCV Library - 2.4.2' library project in your app project as suggested in the tutorials ???(http://docs.opencv.org/trunk/doc/tutorials/introduction/androidbinarypackage/androidbinarypackage.html#application-development-with-async-initialization)

NoClassDefFoundError is a typical Java error. The NoClassDefFoundError is given when there is a class file that your code depends on and it is present at compile time but not found at runtime. Do the example codes from OpenCV work?
