How do I inherit parent project(library aar) gradle dependencies in the child project?

I have a project which has a library aar module, it's dependent on Flatbuffers gradle dependency.
api group: 'com.google.flatbuffers', name: 'flatbuffers-java', version: '1.8.0'
I export the aar to another project into libs, and along with the library classes - also want to use flatbuffers.
implementation fileTree(dir: 'libs', include: ['*.aar'])
I don't want to import Flatbuffers into my child project again.
Is there any solve for this scenario?

Android Studio - MavenCentral dependency sync ok, but symbol cannot be resolved

So, I managed to create an Android library component and publish it on Maven Central. But when I'm trying to use it as a dependency in a new project, Android Studio can't seem to find the classes.
build.gradle for the app module:
repositories {
mavenCentral()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'no.hyper:libdateintervalpicker:1.0.0' //this is the one I want to use
}
This part seems to work, at least I get no sync errors. However, when trying to access to package and classes from my MainActivity, Android Studio can't find them and gives me "cannot resolve symbol" message.
I have tried downloading the classes.jar from the archive directly from Maven Central, and they are indeed in the package.
Other dependencies seem to appear in the /build/intermediates/exploded-aar folder after syncing, but that does not happen to my library.
I use Android Studio 1.0.2 on OSX 10.9.5 (Mavericks)
Any suggestions?

Looking in your pom, it states <packaging>aar.asc</packaging>. It should be aar instead.

Oh, and the answer to actually being able to use the library, was to add #aar to the dependency so that it now reads
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'no.hyper:libdateintervalpicker:1.0.0#aar' //note the magic #aar
}
Edit:
Removing the block
configurations {
archives {
extendsFrom configurations.default
}
}
makes Gradle generate the pom with the correct packaging entry, and thus makes it possible to reference the dependency without the #aar suffix

Can't add External Library in Android Studio?

I Added a External Library to my project by following
this method. and tried this method too this method too.
Gradle build got Finished and i got this line added to my build.gradle
compile 'com.github.castorflex.smoothprogressbar:library-circular:1.0.1'
Now i am trying to import this library in my class. But i can't do this. I took a look at the files and they are located in the build directory under the exploded-aar. so i added #aar to the compile line. Still there are no changes.
How can i import this library to my class or where i am going wrong?
Thanks in Advance

Well, you don't need to download anything or point your dependency to a file.
This dependency, as most of the dependencies you use, can automatically fetched from JCenter, biggest repository for Java and Android components.
All you need to do is:
Add JCenter as your dependencies repository.
Declare that you need the library-circular dependency. This can be found and copy/pasted from the file icon in particular package/version in JCenter.
Resync your Android Studio project with your Gradle build file. This is the 'sync' button in Gradle pane in Android Studio.
Here's what your build.gradle should include:
repositories {
jcenter()
}
dependencies {
compile(group: 'com.github.castorflex.smoothprogressbar', name: 'library-circular', version: '1.0.1', ext: 'aar')
}

in build. gradle put following code
dependencies {
compile fileTree (dir: 'libs', include: ['*.jar'])
}

Did you add the dependencies?
You can do so in the following way -
dependencies {
compile files('insert ParentFolder/external_library_name with the extension here')
}
Add it to build.gradle based in the app folder

1.Put the jar file into the libs folder.
2.Right click it and hit 'Add as library'.
3.Ensure that compile files('libs/abcdef.jar') is in your build.gradle file and Finally add the dependencies.
Eg.
dependencies {
compile fileTree(dir: '../jar', include: '*.jar')
compile project(':pull-to-refresh')
compile files('libraries/abcdef.jar')
}
Hope this helps :)

Android Studio with Gradle incompatibility (Google Play Services issue)

I am developing an android app with Android Studio 0.8.9. I am using Gradle to build my project.
I want to include google-play-services.jar file into my project in order to use push notification api.
I have added those statements into my gradle (application layer) file as follows:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile files('libs/google-play-services.jar')
compile files('libs/android-support-v4.jar')
compile files('libs/gson-2.2.3.jar')
compile files('libs/volley_23042014.jar')
compile 'com.google.android.gms:play-services:5.2.08'
}
but it never works. I get the following error:
Multiple dex files define Lcom/google/ads/AdRequest$ErrorCode;
I've checked bunch of websites (including Stackoverflow.com). None of them has worked for me.
I have latest versions of Google Support Library, Google Support Repository, Google Play Services.
Here is my libs directory
My SDK version like:
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="20" />
What I have done wrong? If anyone has any idea please let me know.

If you're including Play Services via:
compile 'com.google.android.gms:play-services:5.2.08'
you don't need this:
compile files('libs/google-play-services.jar')
so just remove it.
Since the first line of your dependencies will make it automatically pick up any jar files you put in your libs directory:
compile fileTree(dir: 'libs', include: ['*.jar'])
make sure you remove the jars from there as well.
For that matter, there are other libraries you shouldn't include via specific jars.
Instead of this:
compile files('libs/android-support-v4.jar')
compile files('libs/gson-2.2.3.jar')
use this:
compile 'com.android.support:support-v4:20.0.0'
compile 'com.google.code.gson:gson:2.2.3
(Note that later versions of GSON are available).

gradle android proguard error

I am having this issue and seem can't figure it out when building gradle android with proguard:
Can't read [C:\Users\xxx\dev\xyz\Xyz-nextgen\build\exploded-bundles\XyzCommonXyz_volleyUnspecified.aar\libs\android-support-v13.jar(;;;;!META-INF/MANIFEST.MF)] (Duplicate zip entry [android/support/a/a/b.class == android-support-v13.jar:android/support/v13/app/FragmentCompat$FragmentCompatImpl.class])
There are 3 library projects and one app project.
All projects use only one android-support-v13.jar.
Thanks.
Andy

Open the module's gradle.build file and
In
dependencies {
compile 'com.android.support:support-v4:13.0.+'
compile files('libs/android-async-http-1.3.1.jar')
compile fileTree(dir: 'libs', include: '*.jar')
}
Change
compile 'com.android.support:support-v4:13.0.+'
To
compile 'com.android.support:support-v4:21.+'
make sure u have updated build tools in the sdk manager and let us know if that works
