基础知识

• 指定的类和类成员被保留作为 入口 ,使用 -keep
• 保留类成员 ，使用-keepclassmembers
• 保留指定的类和类成员被保留，假如指定的类成员存在的话。使用keepclasseswithmembers

基础知识部分可以看上面第2个链接，假定项目下有2个library,一个application模块，总共3个模块。先说明下gradle配置

• 主工程 ，gradle如下,在这里定义一个统一开关，管理所有模块的混淆开关

ext {    minSdkVersion = 16    targetSdkVersion = 22    compileSdkVersion = 25    buildToolsVersion = '25.0.3'    minifyEnabled = true}

• app模块 ，所有模块可以统一使用framework下的混淆文件proguard-rules.pro，framework是一个library模块，下面是app模块的 gradle文件，

      buildTypes {        debug {            minifyEnabled false            zipAlignEnabled false            shrinkResources false        }        release {            signingConfig getSignInfo("./sign.properties")            minifyEnabled rootProject.ext.minifyEnabled            zipAlignEnabled true            proguardFiles getDefaultProguardFile('proguard-android.txt'), "${project.rootDir}/framework/proguard-rules.pro"        }    }

• library模块 framework下的gradle文件

      buildTypes {        debug {            buildConfigField("boolean", "isDebug", "true") // 定义 isdubug 的值            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }        release {            buildConfigField("boolean", "isDebug", "false") // 定义 isdubug 的值            minifyEnabled rootProject.ext.minifyEnabled            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }

• proguard-rules.pro 的通用部分

• 其它常用控件混淆

*-ignorewarnings 这个是用来忽略一警告的，如果遇到错误可以

项目内部定义的实体类，数据库等可以使用相应的命令。第三方项目如果找不到官方说明如何混淆，可以使用下面的试试

-keepclasseswithmembers xx.xx.xx.**{*;}-keep interface xx.xx.xx..**{*;}-keep enum xx.xx.xx..**{*;}
