I've been trying to figure this out for hours now. I simply want to import my library project into my project by reference. Importing a copy is not an option.
My settings.gradle looks like this
include ':app'
include ':FunLib'
project(':FunLib').projectDir = new File(rootProject.projectDir,'../FunLib/library')
My project's build.gradle
implementation project(':FunLib')
I wish I could point to the parent directory 'FunLib', but that simply doesn't work. So I have to point to the module which is 'library'.
Because my library's root build.gradle is outside of the 'library' directory, my plugins aren't getting recognized because I set my repo urls theres. I don't even know if it's using the right gradle version. I tried copying everything from my library root build.gradle to my project root build.gradle. Nothing has worked. Any project code that references code in my library is a compilation error. What am I missing here?
I finally realized that you don't really import a project. You import a module.
I am trying to create android aar which uses play services. I have added playservices dependency in library gradle file. But when aar is exported in release mode runtime it is not working.
How to add google play services in aar?
Please help
You may want to check these steps in adding your library as a dependency:
Add the library to your project in either of the following ways (if you created the library module within the same project, then it's already there and you can skip this step):
Add the compiled AAR (or JAR) file (the library must be already built):
Click File > New > New Module.
Click Import .JAR/.AAR Package then click Next.
Enter the location of the compiled AAR or JAR file then click Finish.
Import the library module to your project (the library source becomes part of your project):
Click File > New > Import Module.
Enter the location of the library module directory then click Finish.
The library module is copied to your project, so you can actually edit the library code. If you want to maintain a single version of the library code, then this is probably not what you want and you should instead add the compiled AAR file as described above.
Make sure the library is listed at the top of your settings.gradle file, as shown here for a library named "my-library-module":
include ':app', ':my-library-module'
Open the app module's build.gradle file and add a new line to the dependencies block as shown in the following snippet:
dependencies {
compile project(":my-library-module")
}
Click Sync Project with Gradle Files.
But, if it's an app module that you want to reuse, you can turn it into a library module by following these steps to convert an app module to a library module:
Open the module-level build.gradle file.
Delete the line for the applicationId. Only an Android app module can define this.
At the top of the file, you should see the following:
apply plugin: 'com.android.application'
Change it to the following:
apply plugin: 'com.android.library'
Save the file and click Tools > Android > Sync Project with Gradle

As play-services now a days contains aar library instead of jar, we can not merge aar file with library i.e. another aar file. And, hence it is not possible to add play-services inside aar file. Best solution for this problem is who ever is using aar made by you, tell them to add play-services dependency in project.
Add a new module to your project and select import .JAR/.AAR Package.
After you added the module proceed like this : Project Structure → Select the app module → Dependencies tab → clieck the + button → select the module you added → Ok
I have a module with a .aar file in libs folder. I used the solution posted here
[1]: http://kevinpelgrims.com/blog/2014/05/18/reference-a-local-aar-in-your-android-project/ to add the .aar file as dependency and was able to compile the module properly.
Now I want to use this module as a dependency to the main module in my project and compile. However when i try to compile, i do see an error which says that gradle was not able to find the particular .aar file. why would my main module not find a file which is in the libs folder of my sub module. Was wondering if anyone came across this issue.
my project structure is like this
--mainmodule
--build.gradle (submodule as a dependency)
--submodule
--libs
-- abc.aar
Here is the error gradle throws: When unzipping library ':abc:, either group, name or version is empty
If I understand your problem right and you've followed the steps described in the link you shared, then adding this to your mainmodule's build.gradle should do the job:
flatDir {
dirs "../submodule/libs"
}
You basically have the same issue that you fixed in your submodule, since the mainmodule is struggling to resolve transitive dependencies (abc.aar) of submodule.
Recommended way:
While the answer above should fix your issue, Android Studio supports a better way to do this. Import a local aar file via the File>New>New Module>Import .JAR/.AAR Package option in Android Studio v1.3+.
You can then have your submodule depend on that aar-module as follows:
dependencies {
compile project(':aar-module')
}
I want to add external library https://github.com/foursquare/foursquare-android-oauth to my Android application (I use Android Studio, the instructions provided by lib author for Eclipse didn't work for Android Studio).
I've tried to do it with maven, so in File->Project Structure->Dependencies I've added com.foursquare:foursquare-android-nativeoauth-lib:1.0.0 but Gradle Sync fails:
Error:Failed to find: com.foursquare:foursquare-android-nativeoauth-lib:1.0.0
When I try to build my app (without fixing above error becaus I don't know how) I get:
Error:A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugCompile'.
> Could not resolve com.foursquare:foursquare-android-nativeoauth-lib:1.0.0.
Required by:

> Could not find any version that matches com.foursquare:parent:1.0.0.
Any other way to import this lib? I can simply copy-paste source code into my source or create JAR out of it?
BTW: if you run into problems see this question (I had this issue after importing): Manifest merger failed : uses-sdk:minSdkVersion 14
Try one of these approaches:
Approach 1)
1- Choose project view
2- Copy your JAR file in app -> lib folder
3- Right click on your JAR file and choose add as library
4- Check it in build.gradle
Approach 2)
1- File -> New -> New Module
2- Import .JAR/.AAR Package
3- Browse your JAR File
4- Finish
5- File -> Project Structure -> Dependencies
6- You should click on + button and then click on Module Dependency
7- You will see your library here
8- choose your library and click ok
9- Then, you will see that your library is added.
For first two approaches, you need a JAR file. You can search http://search.maven.org/ to find JAR files that are related to Android. For example, this is the search result for jdom in this link
Approach 3) Android is using http://jcenter.bintray.com/ as remote library. For example, this is the search result for jdom in the link.
To add a library in this approach, please follow these steps:
1- File -> Project Structure -> Dependencies
2- Click on + button and choose library dependency
3- find your library and select it, then click OK.
Try this:
File > Project Structure > Dependencies Tab > Add module dependency (scope = compile)
Where the module dependency is the project library Android folder.
To reference an external lib project without copy, just do this:
- Insert this 2 lines on setting.gradle:
include ':your-lib-name'
project(':your-lib-name').projectDir = new File('/path-to-your-lib/your-lib-name)
Insert this line on on dependencies part of build.gradle file:
compile project(':your-lib-name')
Sync project
There are two simplest ways if one does not work please try the other one.
Add dependency of the library inside dependency inside build.gradle file of the library you are using, and paste your library in External Libraries.
OR
Just Go to your libs folder inside app folder and paste all your .jar e.g Library files there, Now the trick here is that now go inside settings.gradle file now add this line include ':app:libs' after include ':app' it will definitely work.
Any other way to import this lib? I can simply copy-paste source code
into my source or create JAR out of it?
Complete Steps for importing a library in Android Studio 1.1
Goto File -> Import Module.
Source Directory -> Browse the project path.
Specify the Module Name
Open build.gradle (Module:app) file
Add the following line with your module name
compile project(':internal_project_name')
Taken from: how to add library in Android Studio
I had also faced this problem. Those time I followed some steps like:
File > New > Import module > select your library_project. Then include 'library_project' will be added in settings.gradle file.
File > Project Structure > App > Dependencies Tab > select library_project. If library_project not displaying then, Click on + button then select your library_project.
Clean and build your project. The following lines will be added in your app module build.gradle (hint: this is not the one where classpath is defined).
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':library_project')
}
If these lines are not present, you must add them manually and clean and rebuild your project again (Ctrl + F9).
A folder named library_project will be created in your app folder.
If any icon or task merging error is created, go to AndroidManifest file and add <application tools:replace="icon,label,theme">
A late answer, although I thought of giving an in-depth answer to this question. This method is suitable for Android Studio 1.0.0 and above.
STEPS
First switch your folder structure from Android to Project.
Now search for the libs folder inside app - build folder.
Once you have pasted the .jar file inside libs folder. Right click on the jar file and at end click on Add as library. This will take care of adding compile files('libs/library_name.jar') in build.gradle [You don't have to manually enter this in your build file].
Now you can start using the library in your project.
For the simplest way just follow these steps
Go to File -> New -> Import Module -> choose library or project folder
Add library to include section in settings.gradle file and sync the project (After that you can see new folder with library name is added in project structure)
include ':mylibraryName'
Go to File -> Project Structure -> app -> dependency tab -> click on plus button
Select module dependency -> select library (your library name should appear there) and put scope (compile or implementation)
Add this line in build.gradle in app level module in dependency section
implementation project(':mylibraryName')
Three ways in android studio for adding a external library.
if you want to add libarary project dependency in your project :
A. In file menu click new and choose import module choose your library project path and click ok, library project automatically add in your android studio project .
B. Now open your main module(like app) gradle file and add project dependency in dependency section dependencies {
compile project(':library project name')
if you want to add jar file :
A. add jar file in libs folder.
B. And Add dependency
compile fileTree(dir: 'libs', include: '*.jar') // add all jar file from libs folder, if you want to add particular jar from libs add below dependency.
compile files('libs/abc.jar')
Add Dependency from url (recommended). like
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
Android studio doesn't use Maven, it use Gradle, you can open your build.gradle the route should be: /app/build.gradle and add the Gradle dependency that shows on the repo:
The build.gradle has a dependencies section:
dependencies {
//here add your dependency
}
The repo says that you need to add this dependency:
compile 'com.foursquare:foursquare-android-oauth:1.0.3'
only add that line to your dependencies on buil.gradle, save the file, and android will rebuild the project, that's all
If the library you need is on GitHub then adding it to Android Studio is easy with JitPack.
Step 1. Add the jitpack repository to build.gradle:
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" }
}
}
Step 2. Add the GitHub repository as a dependency:
dependencies {
// ...
compile 'com.github.Username:LibraryRepo:ReleaseTag'
}
JitPack acts as a maven repository and can be used much like Maven Central. The nice thing is that the maintainers don't have to upload the library. Behind the scenes JitPack will check out the code from GitHub and compile it. Therefore for this to work there needs to be a working build file in the git repository.
There is also a guide on how to publish an Android library.
Turn any github project into a single line gradle implementation with this website
https://jitpack.io/
Example, I needed this project:
https://github.com/mik3y/usb-serial-for-android
All I did was paste this into my gradle file:
implementation 'com.github.mik3y:usb-serial-for-android:master-SNAPSHOT'
There are some changes in new gradle 4.1
instead of compile we should use implementation
implementation 'com.android.support:appcompat-v7:26.0.0'
1.Goto File -> New -> Import Module
2.Source Directory -> Browse the project path.
3.Specify the Module Name – it is used for internal project reference.
Open build.gradle (Module:app) file.
implementation project(':library')
I had the same problem. This happened because of core library dependency. I was using javax.* . This is what i did to fix
In File->Project Structure->Dependencies I added this as as provided file, not a compile. Then re build the project.
This problem started after upgrade of android studio. But I think it happens when you try to edit you build files manually.
Adding library in Android studio 2.1
Just Go to project -> then it has some android,package ,test ,project view
Just change it to Project View
under the app->lib folder you can directly copy paste the lib and do android synchronize it.
That's it
1)just get your lib from here http://search.maven.org/
2)create a libs folder in app directory
3)paste ur library there
4)right click on ur library and click "Add as Library"
5)thats all u need to do!
I hope this will definitely gonna help you!!!!
Could not find any version that matches com.foursquare:parent:1.0.0.
Means that library developer made a mistake in .pom file and specified a wrong one.
I would recommend use the standard approach. You can find .pom file in Maven Repository and use that version or ask developer to take a loot at this problem(via github issue tracker)
compile 'com.foursquare:foursquare-android-oauth:1.1.1'
SIMPLE STEPS TO ADD ANY LIBRARY IN ANDROID STUDIO:
Copy the file in question from any folder in your computer (eg. C:/documents/xyz.jar"), then go to Android Studio and right-click the Project Library folder and select paste.
Now, right click on the newly added Library file and select the option "add as Library"
D.O.N.E
I imported a gradle project from eclipse and I'd like to add some libraries to the project.
The usual approach would be to import a module in the Project Structure window.
The problem is that according to google I can't do that with a gradle project: Android Studio - Project structure is almost empty
If so, in what way that is compatible with gradle projects can I import a library?
In the project window, right click on your project name and new a directory named 'libs'. libs has the same level of build and src.
Copy your jar file to libs within file manager of OS.
Wait for seconds, the jar file will show under libs in android studio. Right click on it and click 'add as library'.
Add info to build.gradle, for example
dependencies {
compile 'com.android.support:appcompat-v7:+'
compile files('libs/NameOfYourFile.jar')
}
Now, you can use the library and build. If you get some errors, Enter project directory and run ./gradlew clean and rebuild your project.
