问题描述

这是有关非自由模块编译主教程。但是，不包括在JNI部分的Java的用户。我寻觅了如何使用编译的.so库，但我无法实现的。

This is the main tutorial about nonfree module compilation. However, the jni part for java users are not included. I have searched how to use compiled .so libraries but I could not achieve.

我不知道，有人可以共享JNI一部分非自由的模块或为其详细解释，因为我的工作在这个问题上超过一个星期，我不能这样做。

I wonder that someone can share the jni part for nonfree modules or detailed explanation for it, because I work on that issue over a week and I could not do it.

感谢。

推荐答案

假设你已经得到了OpenCV的4机器人工作在Android设备上;

Assuming that you've already gotten OpenCV 4 Android to work on your Android device;

1）我把libnonfree.so，libopencv_java.so和libgnustl_shared.so（不知道是否需要的最后一个）在正确的文件夹为您的平台，在我的情况jniLibs / armeabi-V7A。已编译的版本可以在这里找到demo文件夹; https://github.com/bkornel/opencv_android_nonfree

1) I placed libnonfree.so, libopencv_java.so and libgnustl_shared.so (not sure if the last one is needed) in the correct folder for your platform, in my case jniLibs/armeabi-v7a. Already compiled version can be find in the demo folder here; https://github.com/bkornel/opencv_android_nonfree

2）请确保您加载这两个库。

2) Make sure you load both libraries.

static {
    System.loadLibrary("opencv_java");
    System.loadLibrary("nonfree");
}

这是被要求，以便为这一切为我工作。

This was all that was required in order for it to work for me.
