How To Add .aar Dependency In Library Module?

I am having one .aar file of one library module. I want to use it as a library or dependency in my other project's library module. How do I do it? I tried options provided at bel

Solution 1:

Follow this setting and you will able to add .aar dependency to library module

build.gradle (Project: ....)

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        flatDir {
            dirs'libs'dirs project(':library_module').file('libs')
        }
    }
}

build.gradle (Module: app)

dependencies {
    ...
    compile project(':library_module')
}

build.gradle (Module: library_module)

dependencies {
    ...
    compile(name:'aar_file_name', ext:'aar')
}

settings.gradle (Project Settings)

include':app', ':library_module'

Solution 2:

In all modules (library or application) where you need the aar file you have to add in your build.gradle the repository:

repositories {
    flatDir {
        dirs'libs'
    }
}

and add the dependency:

dependencies {
   compile(name:'nameOfYourAARFileWithoutExtension', ext:'aar')
 }

You can use the top-level file to add the repositories, but you can't add the dependencies in the top-level file. Pay attention to the relative path of the libs folder that you are using in the module.

Solution 3:

Sorry process involves 10 steps but these are super simple and easy.

1- New->Module

2- Select import .jar/aar package

3- Select your .aar file from location

4- We can see module is added but not configured with app module yet.

5- Go to Project Structure

6- Current project structure is like this one

7- Go to app module and press '+' icon

8- Select 3rd option Module dependency

9- Select newly added .arr module

10- you can see the new module attached with app module. Now click apply.

you can see we are good to go.

Solution 4:

I did it a bit differently than others have posted here...

My main goal was to create a library module that contained all the jar's and aar's that I would need. My main project would then depend on this library module - I only wanted a single line in the main project's build.gradle to link this dependency.

1. Add a new library module to the project: File -> New -> New Module -> Android Library

2. within the library module, open the build.gradle and add:

// so that the library project can locate the aar in /libs
repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation fileTree(include: ['*.aar'], dir: 'libs')
}

now you can pop all the jar's and aar's into the /libs folder of your library module. Bonus: whatever the library name is doesn't matter, it's automatically discovered

Solution 5:

1. File -> New Module -> Import .JAR/.AAR
2. import the .AAR file.
3. in library module build.gradle add the dependency dependencies{compile project(':Name-Of-Your-Module-aar')}
