AndroidStudio上的JavaCV安装错误。无法找到* .so

Question

我使用Android Studio开发Android应用程序。我已经使用Camera2 API构建了我的应用程序的相机部分，现在我想使用JavaCV处理图像（为了获取我正在进行的帧和ImageReader，但它给了我YUV_420_888帧，我甚至无法保存一个好的形状）。

所以我在这里关注了AndroidC的JavaCV manualy安装教程： https://github.com/bytedeco/javacv

当我写一些代码时，找到了库。 但是当我执行这个时：

        opencv_highgui.CvCapture capture = opencv_highgui.cvCreateCameraCapture(opencv_highgui.CV_CAP_ANDROID);

我得到了这个（警告，很多废话）：

最后：

  

CameraWrapperConnector :: connectToLib错误：无法dlopen相机包装库   Native_camera返回了打开错误：4

那么，我的libs是什么样的？

我没有碰到Gradle。为了使用这些jar，我添加了它们：Project Structure＆gt; app＆gt; dependecies＆gt;添加文件依赖项

我尝试了很多在互联网上流行的安装版本，最后我决定使用官方教程返回良好的基础。

像这样，我可以问你安装JavaCV的好方法是什么？我的意思是它终于可以找到那些错过的库吗？我在这上面花了很多时间，我还不太确定...... Ps：Sry因为我的英语不好而且我对你的所有问题持开放态度。

您可以使用gradle完全安装JavaCV。请看一下这个答案，你应该能够正确安装它。

举个例子，尝试将以下行添加到您的gradle文件并删除.jar文件：

compile group: 'org.bytedeco', name: 'javacv', version: '0.11'
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '2.4.11-0.11', classifier: 'android-arm'
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.6.1-0.11', classifier: 'android-arm'
