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  actionbarsherlock aar    What I m trying to do is actually use this aar to build my final APK   If I include the whole ActionBarSherlock library as an android-library module to my main project using compile project    actionbarsherlock   I m able to build successfully without any problems   But my problem is that I want to provide that dependency as a aar file package MANUALLY just if I would a JAR then I can t seem to figure out how to properly include it into my project   I ve attempted to use the compile configuration but this doesn t seem to work   I keep on getting cannot find symbol during compile which tells me that the classes jar from aar package isn t getting included in the classpath   Does anyone know of the syntax to manually include an aar package as a file   build gradle   buildscript     repositories        mavenCentral         dependencies       classpath  com android tools build gradle 0 4        apply plugin   android   repositories      mavenCentral     dependencies       compile files  libs actionbarsherlock aar      android       compileSdkVersion 15     buildToolsVersion  17 0      EDIT  So the answer is that it s not currently supported  here s the issue if you want to track it   EDIT  Currently as this is still not supported directly the best alternative seems to be the proposed solution from  RanWakshlak  EDIT  Also simpler by using the syntax proposed by  VipulShah

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 - gt      dependencies add  compile    name  file name lastIndexOf      with   it    -1   file name 0   lt it    file name    ext   aar

Currently referencing a local  aar file is not supported  as confirmed by Xavier Ducrochet   What you can do instead is set up a local Maven repository  much more simple than it sounds  and reference the  aar from there   I ve written a blogpost detailing how to get it working here   http   www flexlabs org 2013 06 using-local-aar-android-library-packages-in-gradle-builds

There are 2 ways   The first way   Open your Android Studio and navigate to the Create New Module window by File - gt  New - gt  New Module       Select the Import  JAR  AAR Package item and click the Next button 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   Create a folder in libs directory  such as aars  Put your aar lib into the aars folder  Add the code snippet    repositories       flatDir           dirs  libs aars            into your build gradle file belongs to the app module    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   If you can read Chinese  you can check the blog    AAR       Android

Please follow below steps to get it working   I have tested it up to Android Studio 2 2  Lets say you have kept aar file in libs folder    assume file name is cards aar   then in app build gradle specify following and click sync project with Gradle files  Open Project level build gradle and add flatDir dirs  libs   like did below allprojects      repositories         jcenter         flatDir           dirs  libs                  and now open app level build grdle file and add  aar file     dependencies          implementation name  cards   ext  aar      If everything goes well you will see library entry is made in build - gt  exploded-aar Also note that if you are importing a  aar file from another project that has dependencies you ll need to include these in your build gradle  too

you can do something like this    Put your local libraries  with extension   jar   aar       into  libs  Folder  or another if you want   In build gradle  app level   add this line into dependences  implementation fileTree include      jar      aar    dir   libs

With Android Studio 3 4 and Gradle 5 you can simply do it like this  dependencies       implementation files  libs actionbarsherlock aar

There is 1 more way to do this  Usually the  aar file is not supposed to be directly used like we use a  jar and hence the solutions mentioned above to mention it in libs folder and declaring in gradle can be avoided  Step 1  Unpack the  aar file  You can do this by renaming its extension from  quot  aar quot  to  quot  zip quot   Step 2  You will most probably find the  jar file in the folder after extraction  Copy this  jar file and paste it in your module libs folder Step 3  That s it  now sync your project and you should be able to access all classes methods  properties from that  jar   You don t need to mention about it s path name existence in any gradle file  this is because the gradle build system always looks out for files existing in libs folder while building the project

In my case I have some depencies in my library and when I create an aar from it I failed  because of missed depencies  so my solution is to add all depencies from my lib with an arr file    So my project level build gradle looks so   buildscript       repositories           mavenCentral             dependencies           classpath  com android tools build gradle 2 1 2           allprojects       repositories           mavenCentral             add it to be able to add depency to aar-files from libs folder in build gradle yoursAppModule          flatDir               dirs  libs                     task clean type  Delete        delete rootProject buildDir     build gradle modile app  so   apply plugin   com android application   android       compileSdkVersion 23     buildToolsVersion  23 0 3       defaultConfig           applicationId  com example sampleapp          minSdkVersion 15         targetSdkVersion 23         versionCode 1         versionName  1 0            buildTypes           release               minifyEnabled false             proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules pro                     dependencies         your project depencies               add lib via aar-depency     compile name   aarLibFileNameHere   ext   aar         add all its internal depencies  as arr don t have it             and library build gradle   apply plugin   com android library   android       compileSdkVersion 23     buildToolsVersion  23 0 3       defaultConfig           minSdkVersion 15         targetSdkVersion 23         versionCode 1         versionName  1 0            buildTypes           release               minifyEnabled false             proguardFiles getDefaultProguardFile  proguard-android txt     proguard-rules pro                     dependencies       compile fileTree include      jar    dir   libs         here goes library projects dependencies  which you must include       in yours build gradle modile app  too

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       You can check out  Min an blog post for more info

Unfortunately none of the solutions here worked for me  I get unresolved dependencies   What finally worked and is the easiest way IMHO is  Highlight the project name from Android Studio then File -  New Module -  Import JAR or AAR Package  Credit goes to the solution in this post

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      More info  Handling-transitive-dependencies-for-local-artifacts-jars-and-aar

I ve also had this problem  This issue report  https   code google com p android issues detail id 55863 seems to suggest that directly referencing the  AAR file is not supported   Perhaps the alternative for now is to define the actionbarsherlock library as a Gradle library under the parent directory of your project and reference accordingly   The syntax is defined here http   tools android com tech-docs new-build-system user-guide TOC-Referencing-a-Library

Just to simplify the answer  If  aar file is locally present then include compile project   project directory   in dependencies of build gradle of your project   If  aar file present at remote then include compile  com           sdk project directory 0 0 1 aar  in dependencies of build gradle of your project

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 the dependency block  implementation files  quot libs someAndroidArchive aar quot

I tried all solution here but none is working  then I realise I made a mistake  I put the  aar in wrong folder  as you can see below  I thought I should put in root folder  so I created a libs folder there  1 in picture   but inside the app folder  there is already a libs  you should put in second libs  hope this help those who has same issue as mine

before default   implementation fileTree include      jar    dir   libs     just add    aar  in include array   implementation fileTree include      jar      aar    dir   libs     it works well on Android Studio 3 x   if you want ignore some library  do like this   implementation fileTree include      jar      aar    exclude   test aar    dir   libs   debugImplementation files  libs test aar-debug aar   releaseImplementation files  libs test aar-release aar

I ve just succeeded    Copy the mylib-0 1 aar file into the libs  folder Add these lines to the bottom of build gradle  should be app  not project    repositories      flatDir          dirs  libs         dependencies       compile  com example lib mylib 0 1 aar     So far so good  Here comes the most important point     Gradle needs to access the network for dependencies unless offline mode is enabled    Make sure that you have enabled Offline work via the checkbox in Project Structures Gradle   -- OR --   Configure the proxy settings in order to access the network   To configure the proxy settings you have to modify the project s gradle properties file  configuring http and https separately as below   systemProp http proxyHost proxy example com systemProp http proxyPort 8080 systemProp http proxyUser user systemProp http proxyPassword pass systemProp http nonProxyHosts localhost systemProp http auth ntlm domain example  lt for NT auth gt   systemProp https proxyHost proxy example com systemProp https proxyPort 8080 systemProp https proxyUser user systemProp https proxyPassword pass systemProp https nonProxyHosts localhost systemProp https auth ntlm domain example  lt for NT auth gt    Hope this works
