I have a legacy eclipse Android project. The classic old way without gradle.
Suppose I found a library I want to integrate with, for example 'commons-codec', than quoting from gradle manual https://docs.gradle.org/current/userguide/organizing_build_logic.html#sec:external_dependencies, I need to paste the below in my gradle file:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath group: 'commons-codec', name: 'commons-codec', version: '1.2'
}
}
Now my eclipse project does not use gradle.
The Question: Is there a way to get the binary lib & integrate with it in eclipse (something similar to download the library's jar and add it)? I know this question is bizarre since I need the jar to be in the repository, but I want to be sure I'm not overlooking anything.
Many Thanks!
If you're just using a jar, you can include it in the libs folder of the Eclipse project. But that's code only. If there's resources in the library, you'd need to build an Android Library project out of it and include that in your project. Which I'm not sure how you'd do without code.
If you are having .jar file the simply right click on your project then
Properties-->Java Build Path-->Libraries-->Add Jar/ Add External Jar--> Apply
And if you are having library in your workspace then
Properties-->Android-->Add-->locate your library-->Apply

I have to create an application that makes extensive use of charts.
Reading the web I chose achartengine that seems to have everything I need.
I downloaded the jar file, I plugged in the libs folder, I selected "add to library" and I lunch the gradlew clean.
Result in the sources where I do the import of org.achartengine.xxxx I always returned the error that fails to resolve symbols .
Do you have suggestions?
Thank you

I am able to use this library in my Android Studio project, this topic explains how to add AChartEngine repo to your project.
What I did:
Added following to project-wide build.gradle (one from the project root):
allprojects {
repositories {
...
maven {
url "https://repository-achartengine.forge.cloudbees.com/snapshot/"
}
}
}
For every module that uses the library, add this to its build.gradle (you may put this to the top-level build.gradle if it should be included in all modules):
dependencies {
...
compile group: 'org.achartengine', name: 'achartengine', version: '1.2.0'
}
Now I can use the library in the project, I see the classes in code assist popups and build runs as succeeds.
It seems like the new version (1.2.0) is not available for download anymore in the http://www.achartengine.org/ site. and that's why the gradle/maven method doesn't work (or the snapshot file was removed).
I succeeded using and adding it to my project by downloading the jar file from here:
https://github.com/ddanny/achartengine/files/460139/achartengine-1.2.0.zip
The title is a little misleading but I honestly don't know how to word it in any other way. This is my project structure:
I want to use the highlighted (fasteranimationscontainer-master) in my current app that I'm working on. I imported it by putting the jar file in my library folder then adding it to my library through Android Studio. But I try to create an object of that imported library, it doesn't show up/import.
I'm still learning how to use android studio so any help would be much appreciated!
1. Library with only the Source Code
To include a library with only the source code (like FasterAnimationsContainer) to your project, you only need to import it as a module from File -> New-> Import Module in Android Studio:
There should be a dialog for the project folder, enter the path where your library reside.
Then you need to add the module to your app build.gradle as a dependency:
android {
...
dependencies {
...
compile project(':fasteranimationscontainer')
...
}
}
Now you can use it in your project.
2. Library from Maven or JCenter
To add dependencies to your project where the library has uploaded to maven or jcenter, you need to modify your app build.gradle file and add extra lines configuring the packages you require. For example, for certain Google or Android, dependencies look like:
android {
...
dependencies {
// Google Play Services
compile 'com.google.android.gms:play-services:6.5.+'
// Support Libraries
compile 'com.android.support:support-v4:22.2.1'
}
}
Try to always read the library README first.
Suggestion:
If you still learning using Android Studio, you can read Using Android Studio. Then read Getting Started with Gradle, because Android Studio is tightly related with Gradle.
I am using Android Studio 1.2
I create a private library I want to use that one in another application.
To use it I create an AAR files, but this AAR don't work. I have in my library a dependency to an AAR file.
The AAR files do not the dependencies?
If I use the jar and I includ ans create all the dependencies the project works fine.
NOTE :
I know how to importe the AAR file. The problem is to use an AAR in the AAR..
Thanks.
If I'm understanding your question correctly, there are 3 projects involved:
Library Project 2 --> Library Project 1 --> Application Project
You are editing "Library Project 1" and have added to it's app/build.grade a dependency on the Library Project 2's aar. Something like this: compile 'com.arasthel:gnavdrawer-library:1.1.5'
I am not sure where you are running into an issue, but I'll attempt an answer anyway. If I'm completely off-base, can you please elaborate on how the AAR dependency is not working? Any error messages?, a class/resource not found, etc.
I think it's unlikely you are unable to use a class from Library Project 2 inside Library Project 1, because I just tried this myself and it seems to be working just fine. It's worth noting that the Library Project 1 aar file will NOT include classes or resources from Library Project 2. Library Project 2 will be noted as a dependency in Library Project 1's pom if published using gradle's maven plugin to publish Library Project 1.
My guess is that you are having a problem in the Application Project? Perhaps the class from Library Project 2 is not found in the Application Project?
If that is correct, then there are two possible solutions:
Enable transitive dependencies on the aar dependency in the Application project's app/build.gradle: Instead of compile 'com.example:myLibrary:versionX', make it compile('com.example:myLibrary:versionX'){transitive=true}. I just verified this causes gradle to read Library Project 1's pom and automatically add dependencies found there into the Application Project.
If you would like to use transitive dependencies, your Library Project will need to be generating a pom and publishing it along with the aar. See https://stackoverflow.com/a/30085677/431296 for some additional information on how I have this working.
Manually add the dependency on Library Project 2 to the Application Project - so that your Application has a dependency line for both Libraries. Depending on your specific situation this may or may not be a workable solution.
Add following code to you project build.gradle file, and you should put you AAR file to the libs folder.
repositories {
mavenCentral()
flatDir {
dirs 'libs'
}
}
And finally add compile info to your dependencies:
dependencies {
compile(name:'AARFileName', ext:'aar')
}

We can find some very good open source libraries for android. I want to know what is the best way to integrate them to our own projects in Android studio. Here are some basic methods:
Copy the source code and resource files into our own project. We need to change a lot of codes (the package name, and the name in xml,etc)
If jar files is provided, I just create libs folder for my project and copy the jar files inside. And add the jar file in Module setting's dependencies. But unfortunately I got a lot of error messages like "Gradle: Package com.google.gson doesn't exist".
Is there a general rule to add third party source or jar files into an existing android studio project? Thanks
I prefer to use central repository for dependencies management. So for gson 2.3 dependency you should add to build.gradle file:
Specify that you want to use maven central repository for your dependency
repositories {jcenter()}
Add compile dependency to gson 2.6.2
dependencies {compile 'com.google.code.gson:gson:2.6.2'}
Android Studio as well as your CI server should easily build your project now. And you can continue app development.
I prefer to use central repository for dependencies management because:
easier scope management - some libraries are only for testing, some should be included to apk and some are part of running environment (like android.jar itself)
easier transitive dependencies management - it is quite hard to collect libraries dependencies and if you use "jar-with-dependencies" you could get error "class already added" during dexing
lighter repository and easier dependency upgrade
Examples:
Robolectric jar should be used for unit testing only and shouldn't be part of apk itself
Repository is clean from different folders with jars, checkout takes much less. No needs to download and replace old jars with new jars
I should notice:
Not many libraries are in maven central and you should make some effort to use them such way in your project
You could much easier get to "class already added" error during dexing with central repository approach
You can mix usage of dependencies from central repository and from lib folder, but I prefer to use only one way for simplicity
Put the Gson jar (in my case, gson-2.2.4.jar) into the libs folder
Right click it and hit 'Add as library'
Ensure that compile files('libs/gson-2.2.4.jar') is in your build.gradle file
Do a clean build (you can probably do this fine in Android Studio, but to make sure I navigated in a terminal to the root folder of my app and typed gradlew clean. I'm on Mac OS X, the command might be different on your system
This series of steps was taken from Android Studio: Add jar as library? and is not my original answer. I am posting them here, again, because your question was the third in search results on Google when looking up this same topic. Hence, copying.
All credits to the one who wrote the steps.
Download & Copy Your .jar file in libs folder then adding one line to build.gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar']) ----> AS creates this
compile 'com.google.code.gson:gson:2.3.4' ----------> I added this one
}
Do not forget to click "Sync now"
I´m using Android Studio 1.1.0
Download and copy your jar to libs folder then add the following to your app.gradle file and SYNC.
dependencies {
compile 'com.google.code.gson:gson:{version_you_need}'
}
repositories{
flatDir{
dirs 'libs'
}
}
