What steps will reproduce the problem? 1.trying to run a program on android that uses javacv library 2.exception at "opencv_core.Mat a = imread(file1Path);" 3.I have the followng jars 1.javacv.jar 2.javacpp.jar 3.opencv.jar 4.opencv-android-arm.jar 5.opencv-android-x86.jar What is the expected output? What do you see instead? A mat object has to be created. It gives the exception during run time. The exception is :

What version of the product are you using? On what operating system? I have downloaded the javacv packages from "https://github.com/bytedeco/javacv#sample-usage&quot; on mac os

Please provide any additional information below. I feel that the opencv_core class is not going into the apk as it does not give me any errors during compile time. My import statements are: import org.bytedeco.javacpp.opencv_core; import static org.bytedeco.javacpp.opencv_highgui.imread;

If you are not using Android Studio, please try again with Android Studio.

And please post on GitHub, if possible, this site is no longer maintained, thank you!
