How to manually include external aar package using new Gradle Android Build System

Question

I\'ve been experimenting with the new android build system and I\'ve run into a small issue. I\'ve compiled my own aar package of ActionBarSherlock which I\'ve called \'act

Answer 1

You can reference an aar file from a repository. A maven is an option, but there is a simpler solution: put the aar file in your libs directory and add a directory repository.

    repositories {
      mavenCentral()
      flatDir {
        dirs 'libs'
      }
    }

Then reference the library in the dependency section:

  dependencies {
        implementation 'com.actionbarsherlock:actionbarsherlock:4.4.0@aar'
}

Answer 2

You can add multiple aar dependencies with just few lines of code.

Add local flatDir repository:

repositories {
    flatDir {
        dirs 'libs'
    }
} 

Add every aar in libs directory to compile dependency configuration:

fileTree(dir: 'libs', include: '**/*.aar')
        .each { File file ->
    dependencies.add("compile", [name: file.name.lastIndexOf('.').with { it != -1 ? file.name[0..<it] : file.name }, ext: 'aar'])
}

I found this workaround in the Android issue tracker: https://code.google.com/p/android/issues/detail?id=55863#c21

The trick (not a fix) is to isolating your .aar files into a subproject and adding your libs as artifacts:

configurations.create("default")
artifacts.add("default", file('somelib.jar'))
artifacts.add("default", file('someaar.aar'))

If you use Gradle Kotlin DSL, you need to add a file in your module directory.

For example: libs/someAndroidArchive.aar

After just write this in your module build.gradle.kts in dependency block:

implementation(files("libs/someAndroidArchive.aar"))

There are 2 ways:

The first way

1. Open your Android Studio and navigate to the Create New Module window by File -> New -> New Module

2. Select the Import .JAR/.AAR Package item and click the Next button

3. Add a dependency in the build.gradle file that belongs to your app module.

    dependencies {
        ...
        implementation project(path: ':your aar lib name')
    }

That's all.

The second way

1. Create a folder in libs directory, such as aars.

2. Put your aar lib into the aars folder.

3. Add the code snippet

repositories {
    flatDir {
        dirs 'libs/aars'
    }
}

into your build.gradle file belongs to the app module.

4. Add a dependency in the build.gradle file that belongs to your app module.

dependencies {
    ...
    implementation (name:'your aar lib name', ext:'aar')
}

That's all.

In my case just work when i add "project" to compile:

repositories {
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
}


dependencies {
   compile project('com.x.x:x:1.0.0')
}
