How to include *.so library in Android Studio?

Solution 1:

Adding .so Library in Android Studio 1.0.2

1. Create Folder "jniLibs" inside "src/main/"
2. Put all your .so libraries inside "src/main/jniLibs" folder
3. Folder structure looks like,
   |--app:
   |--|--src:
   |--|--|--main
   |--|--|--|--jniLibs
   |--|--|--|--|--armeabi
   |--|--|--|--|--|--.so Files
   |--|--|--|--|--x86
   |--|--|--|--|--|--.so Files
   
4. No extra code requires just sync your project and run your application.

Solution 2:

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)
}

Solution 3:

Solution 1 : Creation of a JniLibs folder

Create a folder called “jniLibs” into your app and the folders containing your *.so inside. The "jniLibs" folder needs to be created in the same folder as your "Java" or "Assets" folders.

Solution 2 : Modification of the build.gradle file

If you don’t want to create a new folder and keep your *.so files into the libs folder, it is possible !

In that case, just add your *.so files into the libs folder (please respect the same architecture as the solution 1 : libs/armeabi/.so for instance) and modify the build.gradle file of your app to add the source directory of the jniLibs.

sourceSets {
    main {
        jniLibs.srcDirs = ["libs"]
    }
}

EDIT It had to be jniLibs.srcDirs, not jni.srcDirs - edited the code. The directory can be a [relative] path that points outside of the project directory.

Solution 4:

*.so library in Android Studio

You have to generate jniLibs folder inside main in android Studio projects and put your all .so files inside. You can also integrate this line in build.gradle

compile fileTree(dir: 'libs', include: ['.jar','.so'])

It's work perfectly

|--app:

|--|--src:

|--|--|--main

|--|--|--|--jniLibs

|--|--|--|--|--armeabi

|--|--|--|--|--|--.so Files

This is the project structure.
