Android Studio 0.8.2+ and above, could easily import modules. Thanks to TGMCains answer, is simplified, by using Android Studio itself to import OpenCV as a module.

Downloadlatest OpenCV sdk for Android fromOpenCV.organd decompress the zip file.
Import OpenCV to Android Studio, FromFile -> Import Module, choosesdk/javafolder in the unzipped opencv archive.
Update build.gradleunder imported OpenCV module to update 4 fields to match your project build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion and 4) targetSdkVersion.
Add module dependencybyApplication -> Module Settings, and select theDependenciestab. Click+icon at bottom, chooseModule Dependencyand select the imported OpenCV module.
Copylibsfolder undersdk/nativeto Android Studio underapp/src/main.
In Android Studio,rename the copiedlibsdirectory tojniLibsand we are done.

Step (6) is since Android studio expects native libs inapp/src/main/jniLibsinstead of olderlibsfolder. For those new to Android OpenCV, don't miss below steps

includestatic{ System.loadLibrary("opencv_java"); }
For step(5), if you ignore any platform libs like x86, make sure your device/emulator is not on that platform.

OpenCV written is in C/C++. Java wrappers are

Android OpenCV SDK- OpenCV.org maintained Android Java wrapper. I suggest this one.
OpenCV Java- OpenCV.org maintained auto generated desktop Java wrapper.
JavaCV- Popular Java wrapper maintained by independent developer(s). Not Android specific. This librarymightget out of sync with OpenCV newer versions.
