# Creating your own libraries for Android applications

# Create a library available on Jitpack.io

Perform the following steps to create the library:

  • Create a GitHub account.
  • Create a Git repository containing your library project.
  • Modify your library project's `build.gradle` file by adding the following code:
    apply plugin: 'com.github.dcendents.android-maven'
    // Build a jar with source files.
    task sourcesJar(type: Jar) {
        from android.sourceSets.main.java.srcDirs
        classifier = 'sources'
    task javadoc(type: Javadoc) {
        failOnError  false
        source = android.sourceSets.main.java.sourceFiles
        classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
        classpath += configurations.compile
    // Build a jar with javadoc.
    task javadocJar(type: Jar, dependsOn: javadoc) {
        classifier = 'javadoc'
        from javadoc.destinationDir
    artifacts {
        archives sourcesJar
        archives javadocJar

    Make sure that you commit/push the above changes to GitHub.

  • Create a release from the current code on Github.
  • Run gradlew install on your code.
  • Your library is now available by the following dependency:

    compile 'com.github.[YourUser]:[github repository name]:[release tag]'
  • # Creating library project

    To create a libary , you should use File -> New -> New Module -> Android Library. This will create a basic library project.

    When that's done, you must have a project that is set up the following manner:

    [project root directory]
        [library root directory]
        build.gradle //project level
        settings.gradle //this is important!

    Your settings.gradle file must contain the following:

    include ':[library root directory]'

    Your [library root directory] must contain the following:

             [library package]
             [library package]
    build.gradle //"app"-level

    Your "app"-level build.gradle file must contain the following:

    apply plugin: 'com.android.library'
    android {
        compileSdkVersion 23
        buildToolsVersion "23.0.2"
        defaultConfig {
            minSdkVersion 14
            targetSdkVersion 23

    With that, your project should be working fine!

    # Using library in project as a module

    To use the library, you must include it as a dependency with the following line:

    compile project(':[library root directory]')
