android studio 导出jar

1  首先新建一个工程

2  file->new->new module->android library 

3  打开 build.gradle 在末尾添加脚本如下

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

makeJar.dependsOn(build)

4  build->make module"xxx"

5  view->tools window->gradle->module->Tasks->other->makeJar 然后双击它

6  在build/libs目录下能找到sdk
