I am capturing Video frames using OpenCV4Android Java SDK. Then I pass the Mat object for that frame to NDK funtion. This NDK function should receive the mat and perform resize operation using the cv::resize. But I got this errors:

Java side 1- Taking the frame from the video camera:

 public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
        mRgba = inputFrame.rgba();
        mGray = inputFrame.gray();
        grafty.run(message);

        return mRgba;
    }

2- Native function signature

private static native byte[] runGrafty(long frame);

public byte[] run(Mat imageGray) {
    return runGrafty(imageGray.getNativeObjAddr());
}

JNI ... (more)
