Adding local aar files to Gradle build using flatDirs is not working

Question

I m aware of this question  Adding local  aar files to my gradle build but the solution does not work for me   I tried adding this statement to the top level of my build gradle file   repositories       mavenCentral       flatDir           dirs  libs            I ve also put the slidingmenu aar file into  libs and referenced it in the dependencies section  compile  com slidingmenu lib slidingmenu 1 0 0 aar  but it did not work at all   I tried compile files  libs slidingmenu aar   as well but with no luck   What am I missing  Any ideas   P S  Android Studio 0 8 2

For anyone who has this problem as of Android Studio 1.4, I got it to work by creating a module within the project that contains 2 things.

build.gradle with the following contents:

configurations.create("default")

artifacts.add("default", file('facebook-android-sdk-4.7.0.aar'))
the aar file (in this example 'facebook-android-sdk-4.7.0.aar')

Then include the new library as a module dependency. Now you can use a built aar without including the sources within the project.

Credit to Facebook for this hack. I found the solution while integrating the Android SDK into a project.

This solution is working with Android Studio 4 0 1  Apart from creating a new module as suggested in above solution  you can try this solution  If you have multiple modules in your application and want to add aar to just one of the module then this solution come handy  In your root project build gradle add repositories   flatDir       dirs  libs      Then in the module where you want to add the  aar file locally  simply add below lines of code  dependencies   api fileTree include      aar    dir   libs   implementation files  libs  lt yourAarName gt  aar      Happy Coding

I got this working on Android Studio 2 1   I have a module called  Native Ads  which is shared across multiple projects   First  I created a directory in my Native ads module with the name  aars  and then put the aar file in there   Directory structure   libs  aars      lt -- newly created src  build gradle etc   Then  the other changes   Top level Gradle file   allprojects       repositories           jcenter              For module with aar file in it         flatDir               dirs project   Native Ads   file  aars                       App module s build gradle file   - no changes  Settings gradle file  to include the module    include   app  include  Native Ads  project   Native Ads   projectDir   new File rootProject projectDir      path to Native Ads     Gradle file for the Native Ads module   repositories       jcenter       flatDir           dirs  aars          dependencies       compile name  aar file name without aar extension   ext  aar       That s it   Clean and build

If you already use Kotlin Gradle DSL  the alternative to using it this way   Here s my project structure   -root  ----- app  --------- libs    I choose to store the aar here  -------------- my-libs-01 aar  -------------- my-libs-02 jar  --------- build gradle kts    app module gradle  ----- common-libs    another aar folder directory  ----------------- common-libs-01 aar  ----------------- common-libs-02 jar  ----- build gradle kts    root gradle   My app build gradle kts   Using simple approach with fileTree      android related config above omitted     dependencies          you can do this to include everything in the both directory        Inside   root common-libs  amp    root app libs     implementation fileTree mapOf  dir  to  libs    include  to listOf    jar      aar          implementation fileTree mapOf  dir  to     common-libs    include  to listOf    jar      aar           Using same approach like fetching from local   remote maven repository with flatDirs      android related config above omitted     repositories       flatDir           dirs   mutableSetOf File  libs    File     common-libs             dependencies      implementation group       name    my-libs-01   ext    aar      implementation group       name    my-libs-02   ext    jar       implementation group       name    common-libs-01   ext    aar      implementation group       name    common-libs-02   ext    jar       The group was needed  due to its mandatory  not optional has default value   in kotlin implementation  see below      Filename  ReleaseImplementationConfigurationAccessors kt package org gradle kotlin dsl  fun DependencyHandler  releaseImplementation       group  String      name  String      version  String    null      configuration  String    null      classifier  String    null      ext  String    null      dependencyConfiguration  Action lt ExternalModuleDependency gt     null     Disclaimer  The difference using no 1  amp  flatDirs no 2 approach  I still don t know much  you might want to edit comment to this answer   References    https   stackoverflow com a 56828958 3763032 https   github com gradle gradle issues 9272

You can do it this way  It needs to go in the maven format   repositories     maven   url uri  folderName        And then your AAR needs to go in a folder structure for a group id  com example    folderName    com      example         verion            myaar-version aar   Then reference as a dependency   compile  com example myaar version aar   Where version is the version of your aar file  ie  3 0  etc

In my case  I just put the aar file in libs  and add  dependencies               api fileTree dir   libs   include      aar               in build gradle and it works  I think it is similar with default generated dependency   implementation fileTree dir   libs   include      jar

In my case the none of the answers above worked  since I had different productFlavors just adding repositories        flatDir                dirs  libs               did not work  I ended up with specifying exact location of libs directory   repositories  flatDir      dirs  src main libs         Guess one should introduce flatDirs like this when there s different productFlavors in build gradle

Building upon Josiah s answer  here s how I got it to work    Following his instructions  under edit   File -  New-  New Module -  Import  JAR  AAR  and import your  AAR    Then in your project build gradle  not the top level one  the one under  app   add the following  in the dependencies section    dependencies       compile project   Name-Of-Your-Project       Note Name-Of-Your-Project should match the name of the folder that was added after you imported the AAR file  at the same level as app  idea under the top most level folder   Or to put it another way      MyApplication    idea   app   build gradle  here s where to add compile project   ProjectName   to dependency section    ProjectName  added automatically after importing  matching the name of your aar file    build   gradle   etc   This worked for me running Android Studio 0 8 0  Don t forget to synchronize gradle  using toolbar button or in File- Synchronize  after you do this    Thanks to Josiah for getting me going in the right direction    Note  prior to this I tried adding it to the libs folder  trying to manipulate the top level build gradle and the app level build gradle  but none of that worked for my aars files--jar s will work fine  but not the aar files

The easiest way now is to add it as a module    This will create a new module containing the aar file  so you just need to include that module as a dependency afterwards

Edit  The correct way  currently  to use a local AAR file as a build dependency is to use the module import wizard  File   New Module   Import  JAR or  AAR package  which will automatically add the  aar as a library module in your project   Old Answer  Try this   allprojects     repositories       jcenter       flatDir         dirs  libs                    compile name  slidingmenu   ext  aar
