Native Android OpenCV + Unity3D 5

edit

Hello,

I am trying to develop an Unity3D game using the OpenCV Android implementation. Using the ColorBlobDetectorexample (http://opencv.org/platforms/android/o...) I try to obtain some coordinates and give it to Unity to place some objects in these points.

Before this, I have made a simpler example from 0 to test the communication between an Android library (made in Eclipse) and Unity, and I know how to develop an Android plugin for Unity.

In the case of ColorBlobDetector, when I try to call any method (and even some created by myself) I get the following error:

09-27 17:16:19.160: I/Unity(16572): AndroidJavaException: java.lang.UnsatisfiedLinkError: No implementation found for long org.opencv.core.Mat.n_Mat() (tried Java_org_opencv_core_Mat_n_1Mat and Java_org_opencv_core_Mat_n_1Mat__)

I have exported even the OpenCVLibrary3.0.0 as .jar into Unity but still the same.

Could anyone give me some help about this case? If some screenshot or code is needed, I can give it.

Thanks in advance.
