Android的 - 摇篮：复制到本机库

我很新到Android /摇篮构建环境和谷歌helpt我很多，但对于这个我已经尝试了很多东西，但似乎无法得到它的工作！

I am very new to the Android / Gradle build environment, and google helpt me a lot, but for this I have tried a lot of things, but can't seem to get it to work!!

当我尝试加载Vitamio库（它保存为.jar文件在/应用程序/库/ vitamio /，一切顺利，没有摇篮建立自己的错误。但是，当我启动应用程序，它给人的错误那vinit.so'无法找到。该解决方案是手动复制它的静态库....

When I try to load the Vitamio Library (its saved as .jar file inside /app/libs/vitamio/, everything goes well, there are no Gradle build error.. But when I start the app, it gives the error that 'vinit.so' cannot be found.. The solution is copying it manually to the static-libs....

查看问题 - > Vitamio样本误差 - java.lang.UnsatisfiedLinkError中：无法加载VINIT findLibrary返回null

现在我的文件夹结构如下：

Now my folder structure is as following:

ATTEMPT 1
Android工作室，摇篮，OpenCV的和NDK

错误：（69，0）无法找到任务属性jniLibs''：应用程序：packageDebug。

Error:(69, 0) Could not find property 'jniLibs' on task ':app:packageDebug'.

当我试着使用jniFolders，什么都不会发生。

When I try with jniFolders, nothing happens.

我把它放在很多文件夹里面，只是为了尝试。但它并没有任何区别...

I placed it inside a lot of folders, just to try.. But it doesn't make any difference...

我想复制的工作，我必须安装NDK并将其添加到local.properties文件，但现在它提供了以下错误：

I think the copying worked, I had to install NDK and add it to local.properties file, but now it gives the following error:

错误：摇篮：执行失败的任务：应用程序：compileDebugNdk。
  发生起动过程中'命令'的问题/安卓/ NDK / NDK的构建

Error:Gradle: Execution failed for task ':app:compileDebugNdk'. A problem occurred starting process 'command '/android/ndk/ndk-build'

没有任何错误..任何帮助找到的debug.log somehwere，因为错误只字未提怎么回事错了...

Without any errors.. Any help in find a debug.log somehwere, because the error says nothing about whats going wrong...
