Current Solution

Create the folder project/app/src/main/jniLibs, and then put your *.so files within their abi folders in that location. E.g.,

project/
├──libs/
|  └── *.jar       <-- if your library has jar files, they go here
├──src/
   └── main/
       ├── AndroidManifest.xml
       ├── java/
       └── jniLibs/ 
           ├── arm64-v8a/                       <-- ARM 64bit
           │   └── yourlib.so
           ├── armeabi-v7a/                     <-- ARM 32bit
           │   └── yourlib.so
           └── x86/                             <-- Intel 32bit
               └── yourlib.so

Deprecated solution

Add both code snippets in your module gradle.build file as a dependency:

compile fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')
How to create this custom jar:

task nativeLibsToJar(type: Jar, description: 'create a jar archive of the native libs') {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}

tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn(nativeLibsToJar)
}
