这是我从国外网站上看到的配置教程，it works for me!

Follow the below steps to add Open CV in your project as library.

Create a libraries folder underneath your project main directory. For example, if your project isOpenCVExamples, you would create aOpenCVExamples/libraries folder.
Go to the location where you have SDK "\OpenCV-2.4.8-android-sdk\sdk" here you will find thejava folder, rename it toopencv.
Now copy the complete opencv directory from the SDK into the libraries folder you just created.

Now create a build.gradle file in the opencv directory with the following contents

apply plugin: 'android-library'buildscript {    repositories {        mavenCentral()    }    dependencies {        classpath 'com.android.tools.build:gradle:0.9.+'    }}android {    compileSdkVersion 19    buildToolsVersion "19.0.1"    defaultConfig {        minSdkVersion 8        targetSdkVersion 19        versionCode 2480        versionName "2.4.8"    }    sourceSets {        main {            manifest.srcFile 'AndroidManifest.xml'            java.srcDirs = ['src']            resources.srcDirs = ['src']            res.srcDirs = ['res']            aidl.srcDirs = ['src']        }    }}

Edit your settings.gradle file in your application’s main directory and add this line:
```
include ':libraries:opencv'
```
Sync your project with Gradle and it should looks like this
Right click on your project then click on the Open Module Settings then Choose Modules from the left-hand list, click on your application’s module, click on the Dependencies tab, and click on the + button to add a new module dependency.
Choose Module dependency. It will open a dialog with a list of modules to choose from; select “:libraries:opencv”.
Create a jniLibs folder in the /app/src/main/ location and copy the all the folder with *.so files (armeabi, armeabi-v7a, mips, x86) in thejniLibs from the OpenCV SDK.
Click OK. Now everything done, go and enjoy with OpenCV.
