关于混淆proguard的配置

这几天在做自己项目里面代码的混淆，对于代码的混淆的好处不用多说，减小代码的字节码大小，增加反编译代码阅读的复杂度。
如何开启混淆的配置在androidStudio的配置：
在gradle中加入这段代码 ，就可以使用proguard-rules.pro文件中的配置

 buildTypes {
        release {
            signingConfig signingConfigs.releaseConfig
            minifyEnabled true//开启混淆
            shrinkResources true//移除无用的resource文件
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

然后看下proguard-rules.pro的文件中配置：
我大概分了两个区域：基本不用动区域和自定义区域
基本不动区域：

#-------------------------------------------基本不用动区域--------------------------------------------
#---------------------------------基本指令区----------------------------------
#压缩指数

-dontskipnonpubliclibraryclassmembers

-keepattributes Signature
-keepattributes SourceFile,LineNumberTable

-keepclassmembers class * {
    void *(**On*Event);
    void *(**On*Listener);
}
#----------------------------------------------------------------------------

#---------------------------------webview------------------------------------
-keepclassmembers class fqcn.of.javascript.interface.for.Webview {

#-------------------------------------------------------------------------
#---------------------------------4.反射相关的类和方法-----------------------


#----------------------------------------------------------------------------

在混淆有js与原生交互的时候必须把关于关于有交互的类避免混淆

#---------------------------------3.与js互相调用的类------------------------
-keepclassmembers class com.amugua.JSInterface.CustomJavaScriptInterface{ public *; }
-keepclassmembers class com.amugua.JSInterface.ShopCartInterface{ public *; }
-keepclassmembers class com.amugua.JSInterface.LocalStorageJavaScriptInterface{ public *; }
