Make sure you right-click on OpenCV and your app projects and click on
Refresh, sometimes Eclipse does not refresh itself properly. If the
OpenCV-2.4.0 Java project is in your Eclipse workspace and it builds
fine, but your apps give errors, then they aren't referencing the
OpenCV project correctly.
eg: Right-click on one of your projects in Package Explorer, click on
Properties, click on Android, and look in the Libraries section. It
should show a green tick to say it is linked to the OpenCV project,
but if it is a red cross then "Remove" it and click on "Add..." and
double-click on the OpenCV library. Now it should work.
