Getting Started with a library project in Android Studio

So we're working on creating Android Material Awesome, a library which will hopefully incorperate the benefits of Material Design, Twitter's Bootstrap, and FontAwesome. What we really wanted is a project other people can easily include into their projects using gradle dependencies. To do this we needed to create a standalone library project so we could make it as lightweight as possible for including as a dependency, and a sample app that would use it for testing. These are the steps we took to get started in Android Studio (version 1.1).

Create Projects

The first thing we needed to do was to create two new projects, with all the default settings (Blank Activity etc). One for our sample app, and one for our library. We added both of ours into the same GitHub repo, however you can save them wherever you like.

Fix Up Library Project

apply plugin: 'com.jfrog.bintray'

version = libraryVersion

task sourcesJar(type: Jar) {
    from sourceSets.main.allSource
    classifier = 'sources'
}

task javadocJar(type: Jar, dependsOn: javadoc) {

apply plugin: 'com.jfrog.bintray'

version = libraryVersion

task sourcesJar(type: Jar) {
    from android.sourceSets.main.java.srcDirs
    classifier = 'sources'
}

task javadoc(type: Javadoc) {

apply plugin: 'com.github.dcendents.android-maven'

group = publishedGroupId                               // Maven Group ID for the artifact

install {
    repositories.mavenInstaller {
        // This generates POM.xml with proper parameters
        pom {
            project {
                packaging 'aar'

Publish AAR to jCenter and Maven Central

Now I'm going to list how to publish an Android libray to jCenter and then syncronize it with Maven Central:

1. I use "Android Studio" and I have this simple android lib that I would like to be available on maven: CircularImageView

2. In the library folder(module) I have the lib code abovementioned. And applying in the build.gradle of this folder apply plugin: 'com.android.library' I got as output an .aar in the build/outputs/aar/ directory of the module's directory
