Android - Creating your own libraries for Android applications
Start
  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]
    [gradle]
    build.gradle //project level
    gradle.properties
    gradlew
    gradlew.bat
    local.properties
    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:

    [libs]
[src]
   [main]
      [java]
         [library package]
   [test]
      [java]
         [library package]
build.gradle //"app"-level
proguard-rules.pro

    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]')
