        Re-reading your error, it seems you are using a method that is not implement for android. Can you share the OpenCV code you are using ?

          it's a simple code:

          @#include "opencv2/opencv.hpp"
          #include "opencv2/highgui/highgui.hpp"

          using namespace cv;

          int main(int argc, char *argv[])
          {
          namedWindow("output",1);
          Mat output = Mat::zeros(120,350,CV_8UC3);
          putText(output,"Hello world :)", cvPoint(15,70), FONT_HERSHEY_PLAIN,3,cvScalar(0,255,0),4);
          imshow("Output",output);
          waitKey(0);
          return 0;
          }@

            Wild guess but I'd say that either namedWindow, imshow or both are not implemented for android

              Could you recommend a sample code.

                Not really, since you are currently using OpenCV only code, you should rather ask on the OpenCV forum for their support on android

                  Did you resolve this? I'm about to try the same thing on Fedora.

                      No, I couldn't yet. My main problem is sample code at the moment. I couldn't find sample code about this subject. But I found configurations from this "link":http://stackoverflow.com/questions/27562311/how-to-integrate-opencv-into-qt-creator-android-project
                      I hope that helps.

                          Finally, I found it. Configurations are my previous reply. And you must copy libnative_camera_r4.2.0.so(must be compatible with the your android version(this is important)) to project_root/android/libs/armeabi-v7a/ .
                          Then you can watch "this":https://www.youtube.com/watch?v=0ONxIy8itRA video for source code.

                              This is already solved but anyway here is how I do it all the time:
