how to create a jar file from android studio

Question

I have a fairly latest version of android studio, I have created a module under a project which is basically supposed to be a library, when I build it, it creates an \".aar\

Answer 1

Add this in your library's gradle file:

task deleteJar(type: Delete) {
    delete 'libs/traylib.jar'
}

task createJar(type: Copy) {
    from('build/intermediates/packaged-classes/release/')
    into('libs/')
    include('classes.jar')
    rename('classes.jar', 'traylib.jar')
}

createJar.dependsOn(deleteJar, build)

You need to check path of your generated classes.jar: build/intermediates/packaged-classes/release/

Create lib folder in your lib's root folder if it is not there

Go to gradle build: Android Studio --> View --> Toll Windows --> Gradle

Select your module(:library) --> Tasks --> other --> Double click on createJar task
