在以前曾經寫過兩篇文章,關於是生成jar包和引用jar的文章,建議先看這兩篇文章。

Android Studio生成自定義混淆jar包(同時將assets目錄打入jar包)(二)
今天我就給大家交給大家studio如何生成帶混淆的jar包,其實和上一篇文章差不多,只不過是多了一些混淆檔案。首先我們先新建一個module(我把它新建成了一個library)。在用AndroidStudio生成混淆jar的時候也百度過很多文章,但是大多都沒有用。
為了一會給大家演示混淆後的效果,這裡建立了幾個檔案 MainActivity、UserBean、LogUtil詳細見demo
然後再在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目錄下的所有檔案 baseName = SDK_BASENAME + SDK_VERSION destinationDir = file(sdkDestinationPath)}makeJar.dependsOn(deleteBuild, build)
上面的配置具體我就不講解他們是什麼意思了。
因為我們是自己手動混淆了,所以要指定混淆規則,然後開啟module的proguard-rules.pro檔案,將AndroidStudio預設的混淆檔案複製、貼上到proguard-rules.pro中。
我的proguard-rules.pro檔案
全部proguard-rules.pro配置如下
###########################以下是AndroidStudio自帶的混淆配置協議################################ 表示混淆時不使用大小寫混合類名-dontusemixedcaseclassnames# 表示不跳過library中的非public的類-dontskipnonpubliclibraryclasses# 列印混淆的詳細資訊-verbose# Optimization is turned off by default.

最後的我是禁止混淆LogUtil工具類,以便形成對比。根據混淆配置是AndroidStudio預設不混淆MainActivity,我們在也不混淆LogUtil。
然後你就在Terminal中輸入
gradlew makeJar
或者是雙擊 makeJar
我們將生成的jar包解壓可以看到MainActivity和LogUtil沒有被混淆,這就說明成功了。
注意:有可能你在執行命令的時候遇到下面類似的錯誤提示classes.jar is specified twice,說我們的classes.jar 指定了兩次
解決方式:在proguard-rules.pro中將其註釋掉即可
