在以前曾经写过两篇文章，关于是生成jar包和引用jar的文章，建议先看这两篇文章。

今天我就给大家交给大家studio如何生成带混淆的jar包，其实和上一篇文章差不多，只不过是多了一些混淆文件。首先我们先新建一个module（我把它新建成了一个library）。在用AndroidStudio生成混淆jar的时候也百度过很多文章，但是大多都没有用。

为了一会给大家演示混淆后的效果，这里创建了几个文件 MainActivity、UserBean、LogUtil详细见demo

然后再在module的gradle中配置如下

def SDK_BASENAME = "mylibs";def SDK_VERSION = "_v1.0";def sdkDestinationPath = "build/outputs/jar/";def zipFile = file('build/intermediates/bundles/release/classes.jar')task deleteBuild(type: Delete) {    delete sdkDestinationPath + SDK_BASENAME + SDK_VERSION + ".jar"}task makeJar(type: Jar) {    from zipTree(zipFile)    from fileTree(dir: 'src/main', includes: ['assets/**']) // 打包assets目录下的所有文件    baseName = SDK_BASENAME + SDK_VERSION    destinationDir = file(sdkDestinationPath)}makeJar.dependsOn(deleteBuild, build)

上面的配置具体我就不讲解他们是什么意思了。

因为我们是自己手动混淆了，所以要指定混淆规则，然后打开module的proguard-rules.pro文件，将AndroidStudio默认的混淆文件复制、粘贴到proguard-rules.pro中。

我的proguard-rules.pro文件

全部proguard-rules.pro配置如下
