I Have To Add .aar Files As A Library In A Sub Project In Android Studio. It Gives Me An Error.

I have added the .aar files to libs folder in the sub-project. And have given the repositories as: repositories { mavenCentral() mavenLocal() flatDir { dirs 'libs'

Solution 1:

In the repositories of your module: app

repositories {

    flatDir {
        dirs'libs'
    }
}

Add the following in the dependencies of your module: app In the case that your have both a JAR and an AAR file, do the following.

dependencies 
{
  implementation (name: '***library name***', ext: 'aar')
  implementationfileTree(dir: 'libs', include: ['*.jar', '*.aar'], )

}

Solution 2:

You need to set the dependencies too:

compilefileTree(dir: 'libs', include: ['*.jar','*.aar'])

This can be done in the subprojects build.gradle.

Edit: You might need to specify the file itself:

compile(name:'name-of-file',ext:'aar')

Solution 3:

classpath 'com.android.tools.build:gradle:1.3.0'

1. File -> New Module -> Import JAR/AAR Package

2. "File name" select .aar file， example:

d:/myproject/mylib/build/outputs/aar/mylib-release.aar

3. "Subproject name",example:

   mylib-release

4. /app/build.gradle

   dependencies{

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

   compile project(':mylib-release')

   }

Solution 4:

For filename.aar

repositories {
   flatDir {
        dirs'libs'
    }
}

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

Solution 5:

You are adding a aar file in libs folder. The aar file doesn't contain the dependencies, then you have to add these dependencies also in the main project.

In your module1/build.gradle you should have something like:

dependencies {
    compilefileTree(dir: 'libs', include: ['*.jar'])
    compile('com.android.support:appcompat-v7:22.2.1') //for example//..
 }

In your mainModule/build.gradle you have to add all the dependencies used by your module1.

dependencies {
        compilefileTree(dir: 'libs', include: ['*.jar'])
        compile(name:'fileName',ext:'aar')
        compile('com.android.support:appcompat-v7:22.2.1') //for example//...
     }
