If you don't want to use JavaCV this works for me...

<h1>Step 1- Download the Resources</h1>

Download OpenCV Android SDK from <a href="http://opencv.org/downloads.html">http://opencv.org/downloads.html</a>

<h1>Step 2 - Copying the OpenCV binaries into your APK</h1>

Copy libopencv_info.so &amp; libopencv_java.so from 

<code>OpenCV-2.?.?-android-sdk -&gt; sdk -&gt; native -&gt; libs -&gt; armeabi-v7a</code>

to 

<code>Project Root -&gt; Your Project -&gt; lib - &gt; armeabi-v7a</code>

Zip the lib folder up and rename that zip to whatever-v7a.jar.

Copy this .jar file and place it in here in your project

<code>Project Root -&gt; Your Project -&gt; libs</code>

Add this line to your projects build.gradle in the dependencies section

<code>compile files('libs/whatever-v7a.jar')</code>

When you compile now you will probably see your .apk is about 4mb bigger.

(Repeat for "armeabi" if you want to support ARMv6 too, likely not needed anymore.)

<h1>Step 3 - Adding the java sdk to your project</h1>

Copy the java folder from here

<code>OpenCV-2.?.?-android-sdk -&gt; sdk</code>

to

<code>Project Root -&gt; Your Project -&gt; libs</code> (Same place as your .jar file);

(You can rename the 'java' folder name to 'OpenCV')

In this freshly copied folder add a typical build.gradle file; I used this:

<pre><code>buildscript {
 repositories {
 mavenCentral()
 }
 dependencies {
 classpath 'com.android.tools.build:gradle:0.6.+'
 }
}

apply plugin: 'android-library'

repositories {
 mavenCentral();
}

android {
 compileSdkVersion 19
 buildToolsVersion "19"

 defaultConfig {
 minSdkVersion 15
 targetSdkVersion 19
 }

 sourceSets {
 main {
 manifest.srcFile 'AndroidManifest.xml'
 java.srcDirs = ['src']
 resources.srcDirs = ['src']
 aidl.srcDirs = ['src']
 renderscript.srcDirs = ['src']
 res.srcDirs = ['res']
 assets.srcDirs = ['assets']
 }
 }
}
</code></pre>

In your Project Root settings.gradle file change it too look something like this:

<code>include ':Project Name:libs:OpenCV', ':Project Name'</code>

In your Project Root -> Project Name -> build.gradle file in the dependencies section add this line:

<code>compile project(':Project Name:libs:OpenCV')</code>

<h1>Step 4 - Using OpenCV in your project</h1>

Rebuild and you should be able to import and start using OpenCV in your project.

<pre><code>import org.opencv.android.OpenCVLoader;
...
if (!OpenCVLoader.initDebug()) {}
</code></pre>

I know this if a bit of hack but I figured I would post it anyway.

I have posted a new post about how to build an Android NDK application with OpenCV included
using Android Studio and Gradle. More information can be seen <a href="http://hujiaweibujidao.github.io/blog/2014/10/22/android-ndk-and-opencv-development-with-android-studio/" rel="noreferrer">here</a>, I have summarized two methods:

(1) run <code>ndk-build</code> within Gradle task

<pre><code>sourceSets.main.jni.srcDirs = []

task ndkBuild(type: Exec, description: 'Compile JNI source via NDK') {
 ndkDir = project.plugins.findPlugin('com.android.application').getNdkFolder()
 commandLine "$ndkDir/ndk-build",
 'NDK_PROJECT_PATH=build/intermediates/ndk',
 'NDK_LIBS_OUT=src/main/jniLibs',
 'APP_BUILD_SCRIPT=src/main/jni/Android.mk',
 'NDK_APPLICATION_MK=src/main/jni/Application.mk'
}

tasks.withType(JavaCompile) {
 compileTask -&gt; compileTask.dependsOn ndkBuild
}
</code></pre>

(2) run <code>ndk-build</code> with an external tool

Parameters: <code>NDK_PROJECT_PATH=$ModuleFileDir$/build/intermediates/ndk NDK_LIBS_OUT=$ModuleFileDir$/src/main/jniLibs NDK_APPLICATION_MK=$ModuleFileDir$/src/main/jni/Application.mk APP_BUILD_SCRIPT=$ModuleFileDir$/src/main/jni/Android.mk V=1</code>

<h2>OpenCV, Android Studio 1.4.1, gradle-experimental plugin 0.2.1</h2>

None of the other answers helped me. Here's what worked for me. I'm using the tutorial-1 sample from opencv but I will be doing using the NDK in my project so I'm using the <a href="http://tools.android.com/tech-docs/new-build-system/gradle-experimental" rel="nofollow">gradle-experimental</a> plugin which has a different structure than the gradle plugin.

Android studio should be installed, the Android NDK should be installed via the Android SDK Manager, and the <a href="http://docs.opencv.org/2.4/doc/tutorials/introduction/android_binary_package/O4A_SDK.html#get-the-opencv4android-sdk" rel="nofollow">OpenCV Android SDK</a> should be downloaded and unzipped.

This is in chunks of bash script to keep it compact but complete. It's also all on the command line because on of the big problems I had was that in-IDE instructions were obsolete as the IDE evolved.

First set the location of the root directory of the OpenCV SDK.

<pre class="lang-bash prettyprint-override"><code>export OPENCV_SDK=/home/user/wip/OpenCV-2.4.11-android-sdk
cd $OPENCV_SDK
</code></pre>

Create your gradle build files...

First the OpenCV library

<pre class="lang-bash prettyprint-override"><code>cat &gt; $OPENCV_SDK/sdk/java/build.gradle &lt;&lt;'==='


apply plugin: 'com.android.model.library'
model {
 android {
 compileSdkVersion = 23
 buildToolsVersion = "23.0.2"

 defaultConfig.with {
 minSdkVersion.apiLevel = 8
 targetSdkVersion.apiLevel = 23
 }
 }

 android.buildTypes {
 release {
 minifyEnabled = false
 }
 debug{
 minifyEnabled = false
 }
 }
 android.sources {
 main.manifest.source.srcDirs += "."
 main.res.source.srcDirs += "res"
 main.aidl.source.srcDirs += "src"
 main.java.source.srcDirs += "src"
 }

}


===
</code></pre>

Then tell the tutorial sample what to label the library as and where to find it.

<pre class="lang-bash prettyprint-override"><code>cat &gt; $OPENCV_SDK/samples/tutorial-1-camerapreview/settings.gradle &lt;&lt;'==='


include ':openCVLibrary2411'
project(':openCVLibrary2411').projectDir = new File('../../sdk/java')


===
</code></pre>

Create the build file for the tutorial.


<pre><code>cat &gt; $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle &lt;&lt;'==='


buildscript {
 repositories {
 jcenter()
 }
 dependencies {
 classpath 'com.android.tools.build:gradle-experimental:0.2.1'
 }
}

allprojects {
 repositories {
 jcenter()
 }
}

apply plugin: 'com.android.model.application'

model {
 android {
 compileSdkVersion = 23
 buildToolsVersion = "23.0.2"

 defaultConfig.with {
 applicationId = "org.opencv.samples.tutorial1"
 minSdkVersion.apiLevel = 8
 targetSdkVersion.apiLevel = 23
 }
 }

 android.sources {
 main.manifest.source.srcDirs += "."
 main.res.source.srcDirs += "res"
 main.aidl.source.srcDirs += "src"
 main.java.source.srcDirs += "src"
 } 

 android.buildTypes {
 release {
 minifyEnabled = false
 proguardFiles += file('proguard-rules.pro')
 }
 debug {
 minifyEnabled = false
 }
 }
}

dependencies {
 compile project(':openCVLibrary2411')
}


===
</code></pre>

Your build tools version needs to be set correctly. Here's an easy way
to see what you have installed. (You can install other versions via the
Android SDK Manager). Change buildToolsVersion if you don't have 23.0.2.

<pre class="lang-bash prettyprint-override"><code>echo "Your buildToolsVersion is one of: "
ls $ANDROID_HOME/build-tools
</code></pre>

Change the environment variable on the first line to your version number

<pre class="lang-bash prettyprint-override"><code>REP=23.0.2 #CHANGE ME
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/sdk/java/build.gradle
sed -i.bak s/23\.0\.2/${REP}/g $OPENCV_SDK/samples/tutorial-1-camerapreview/build.gradle
</code></pre>

Finally, set up the correct gradle wrapper. Gradle needs a clean directory
to do this.


<pre><code>pushd $(mktemp -d)

gradle wrapper --gradle-version 2.5

mv -f gradle* $OPENCV_SDK/samples/tutorial-1-camerapreview
popd
</code></pre>

You should now be all set. You can now browse to this directory with Android Studio and open up the project.

Build the tutoral on the command line with the following command:

<pre><code>./gradlew assembleDebug
</code></pre>

It should build your apk, putting it in ./build/outputs/apk

Since the integration of OpenCV is such an effort, we pre-packaged it and published it via JCenter here: <a href="https://github.com/quickbirdstudios/opencv-android" rel="noreferrer">https://github.com/quickbirdstudios/opencv-android</a>

Just include this in your module's build.gradle dependencies section

<pre><code>dependencies {
 implementation 'com.quickbirdstudios:opencv:3.4.1'
}
</code></pre>

and this in your project's build.gradle repositories section

<pre><code>repositories {
 jcenter()
}
</code></pre>

You won't get lint error after gradle import but don't forget to initialize the OpenCV library like this in MainActivity

<pre><code>public class MainActivity extends Activity {
 static {
 if (!OpenCVLoader.initDebug())
 Log.d("ERROR", "Unable to load OpenCV");
 else
 Log.d("SUCCESS", "OpenCV loaded");
 }
