I'm trying to get OpenCV 3.0.0 native to run in my Android Studio 1.5 with Gradle experimental 0.4.0.
I can already use the Java components of OpenCV and the regular NDK functions. But as soon as I try to use the namespace cv in my native code I get the following exception (it is shortened. The complete exception was too long):
