android studio 如何打包成jar包

首先新建一个工程名为ActivityLibrary

然后引入一个modoul，取名为mylibrary

打开my library的build写入

task makeJar(type: Copy) {
    delete 'build/libs/mysdk.jar'
    from('build/intermediates/bundles/release/')
    into('build/libs/')
    include('classes.jar')
    rename ('classes.jar', 'mysdk.jar')
}

makeJar.dependsOn(build)

然后在terminal下生成,输入

./gradlew make Jar

然后取出jar包即可
