打开项目中的proguard-rules.pro，将下面的代码复制进去。我的思路是将混淆分为2个主要部分
- 定制化区域。这里边的内容是我们主要需要补充的部分，大致分为4个小部分，我们接下来的步骤主要是补充这4个部分的东西。
- 基本不用动区域。顾名思义，基本不用动。这块的内容我已经写好了，除非有特殊的需求，基本不用改动。。。请叫我雷锋。。。。。

理解完战略级思想后，我们开始第一部分补充-实体类。实体类由于涉及到与服务端的交互，各种gson的交互如此等等，是要保留的。将你项目中实体类都拎出来，用以下语法进行保留。
-keep class 你的实体类所在的包.** { *; }
如我的项目下类User的完整路径为：com.demo.login.bean.User, 那我的混淆如下
#---------------------------------1.实体类----------------------------------keep class com.demo.login.bean.** { *; }#-------------------------------------------------------------------------
当然你的实体类肯定不止这一个，请用上边的方式一一添加，如果你的实体类都在一个包下，那你就幸福了。

第2部分是第三方包。打开你的build.gradle文件，查看你用了哪些第三方的包。
dependencies { compile 'com.github.bumptech.glide:glide:3.7.0' compile 'org.greenrobot:eventbus:3.0.0'
}
我这里用了glide，eventbus。我去他们的官网把已经写好的混淆copy下来。
#---------------------------------2.第三方包-------------------------------#eventBus-keepattributes *Annotation*-keepclassmembers class ** { @org.greenrobot.eventbus.Subscribe <methods>;}-keep enum org.greenrobot.eventbus.ThreadMode { *; }-keepclassmembers class * extends org.greenrobot.eventbus.util.ThrowableFailureEvent { <init>(java.lang.Throwable);}#glide-keep public class * implements com.bumptech.glide.module.GlideModule-keep public enum com.bumptech.glide.load.resource.bitmap.ImageHeaderParser$** { **[] $VALUES; public *;}#-------------------------------------------------------------------------一般官网都是有混淆的，没有的话就google，也没有的话自己按照上面的写法自己写，还不会的话。。。。。只能换个包。。。。。如果你是直接包含的jar包的话，你这样写
#---------------------------------2.第三方包-------------------------------#log4j-libraryjars log4j-1.2.17.jar-dontwarn org.apache.log4j.**-keep class org.apache.log4j.** { *;}#-------------------------------------------------------------------------
大致意思就是不混淆，不报warn。如果gradle报错的话，可以考虑注释掉-libraryjars log4j-1.2.17.jar这句。

第三部分与js互调的类，工程中没有直接跳过。一般你可以这样写
-keep class 你的类所在的包.** { *; }
如果是内部类的话，你可以这样
-keepclasseswithmembers class 你的类所在的包.父类$子类 { <methods>; }
例如
-keepclasseswithmembers class com.demo.login.bean.ui.MainActivity$JSInterface { <methods>; }
5
第四部分与反射有关的类，工程中没有直接跳过。类的话直接这样
-keep class 你的类所在的包.** { *; }
熟练后不用五分钟就能搞定。大家可以把自己写完混淆所用的时间写在评论里（0，0）

将build.gradle中minifyEnabled设置为true打个包试试吧
release {
minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' }本文章为转载内容，我们尊重原作者对文章享有的著作权。如有内容错误或侵权问题，欢迎原作者联系我们进行内容更正或删除文章。
