JavaCV + Android的工作室+ gradle-可能吗？ [英] JavaCV + Android Studio + gradle- possible?

问题描述

我试图与Android Studio和摇篮使用JavaCV。我写了这样的code片段：

I'm trying use JavaCV with Android Studio and Gradle. I wrote such code fragment:

   repositories {
    mavenCentral()
    maven {
        url "http://maven2.javacv.googlecode.com/git/"
    }
}

dependencies {
    compile files('libs/android-support-v4.jar')
    compile group: 'com.googlecode.javacpp', name: 'javacpp', version: '0.5'
    compile group: 'com.googlecode.javacv', name: 'javacv', version: '0.5'
}

和我看到DIR外部库导入库。所以，我想运行此：

and I see imported libraries in dir External Libraries. So I tried to run this:

...
  IplImage zdjecie=cvLoadImage(Environment.getExternalStorageDirectory().getPath()+ "/1.bmp");
    cvSaveImage(Environment.getExternalStorageDirectory().getPath()
    + "/2.bmp", zdjecie);
...

和我有错误：

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load jniopencv_core: findLibrary returned null

......，因为我不知道我应该怎么做的OpenCV的（及其他）.so文件。

...because I don't know what should I do with opencv's (and others) .so files.

那么我们应该怎么使用JavaCV在Android的工作室？

So how should we use JavaCV in Android Studio?

推荐答案

1.WARNING： 这是不够的：

1.WARNING: That's not enough!:

  dependencies { compile group: 'org.bytedeco', name: 'javacv', version: '0.9'}

2.EDIT：对不起，错，我最近的解决方案，  我张贴在这里并告诉只有约线之上是错误的。但我检查出来，这对我的作品：

2. Sorry for mistake, my recent solution which I posted here and which told only about line above was wrong. But I checked it out and this works for me:

一）添加依赖

dependencies {
    compile group: 'org.bytedeco', name: 'javacv', version: '0.9'
    compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '2.4.9-0.9', classifier:    'android-arm'
    compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.3-0.9', classifier: 'android-arm'    
}

二）创建的 jniLibs 目录的项目中（在同一水平上正常库目录编辑：如果 你有一些麻烦尝试移动jniLibs到应用程序/ src目录/主）。
c）增加要求。所以从OpenCV中，Android的arm.jar和ffmpeg的，Android的arm.jar（或只有这个文件，你真的需要）来创建jniLibs目录提取文件。 （如果你不知道什么 我说你可以从 JavaCV页面和里面下载javacv-0.9-bin.zip 你可以找到这两个.jar文件）。

b) Create jniLibs dir inside your project (on the same level as normal libs dir. If you have some troubles try moving jniLibs to app/src/main).
c) Add required .so files extracted from opencv-android-arm.jar and ffmpeg-android-arm.jar (or only this files which you really need) to created jniLibs dir. (If you don't know about what I'm talking you can download javacv-0.9-bin.zip from JavaCV page and inside it you can find these 2 .jars).
