OpenCV和Android - 使用FLANN制作Feautre

Question

我的代码在这行代码中出现错误：

matcher = DescriptorMatcher.create(DescriptorMatcher.BRUTEFORCE_HAMMING);

这是错误：

java.lang.UnsatisfiedLinkError: No implementation found for long org.opencv.features2d.DescriptorMatcher.create_1(int) (tried Java_org_opencv_features2d_DescriptorMatcher_create_11 and Java_org_opencv_features2d_DescriptorMatcher_create_11__I)
                                                   at org.opencv.features2d.DescriptorMatcher.create_1(Native Method)
