android studio代码混淆配置

android studio代码混淆文本编写

-在build.gradle里面开启minifyEnabled *true

build.gradle配置

 debug {               minifyEnabled true            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.pro'        }        /*注：proguard-project.pro为混淆文本名称

主工程目录下创建proguard-project.pro

-配置如下

注：关于代码混淆做法基本是以上内容，除第三方jar包的配置需要区分处理，其他配置基本通用。

第三方jar包的配置优先推荐去官网下载sdk 会有混淆做法，当然熟练的话完全可以自己配置。
-jar包配置

第三方jar有两种依赖方式

1.maven不需要声明该jar包

使用-keep包名跳过混淆

-dontwarn忽略混淆警告

2.libs下本地依赖jar包
需要声明

-libraryjars libs/**.jar

使用-keep包名跳过混淆

-dontwarn忽略混淆警告
