教你5步搞定代码混淆

代码混淆是上线前必不可少的一部分操作，作为一个高逼格程序员，怎么让自己的混淆看起来更专业，更高逼格呢！简单来说，有条理，让人一目了然，当然这是给你同伴看滴，对于那些想要反编译的朋友来说还是越难懂越好咯。不多说，看文档；

分为5部分：
=================== 定制化区域=================
1. 实体类区域
项目中的实体类，最好放在一个包下，如果没有也没关系，一个个添加下就可以了！比如我的实体类大多数放在entity包下面，所以就这样写：

-keep class com.qmovies.media.TV.entity.** { *; }

第三方包区域
项目中使用第三方包是很难避免的！一般所使用的第三方包官方都会有提供，如果没有，那就Google或者百度，实在找不到，就自己写吧：

贴一下我常用的包，这些包的混淆配置在下面都有配置。
compile ‘com.google.code.gson:gson:2.8.0’
compile ‘com.android.support:appcompat-v7:25.1.1’
compile ‘com.android.support:support-v4:25.1.1’
compile ‘com.android.support:design:25.1.1’
compile ‘com.flyco.tablayout:FlycoTabLayout_Lib:2.0.0@aar’
compile ‘com.miguelcatalan:materialsearchview:1.4.0’
compile ‘com.jakewharton:butterknife:8.4.0’
compile ‘io.reactivex:rxandroid:1.1.0’
compile ‘io.reactivex:rxjava:1.1.0’
compile ‘com.artemzin.rxjava:proguard-rules:1.2.9.0’
compile ‘com.github.bumptech.glide:glide:3.7.0’
compile ‘com.trello:rxlifecycle-components:0.6.1’
compile ‘com.facebook.stetho:stetho:1.3.1’
compile ‘com.facebook.stetho:stetho-okhttp3:1.3.1’
compile ‘com.google.code.gson:gson:2.8.0’
compile ‘com.squareup.retrofit2:retrofit:2.0.0-beta4’
compile ‘com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4’
compile ‘com.squareup.retrofit2:converter-gson:2.0.0-beta4’
compile ‘com.squareup.okhttp3:okhttp:3.2.0’
compile ‘com.squareup.okhttp3:logging-interceptor:3.2.0’
compile ‘com.android.support:cardview-v7:25.1.1’
compile ‘com.google.android.exoplayer:exoplayer:r2.2.0’
compile ‘org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2’
testCompile ‘junit:junit:4.12’
apt ‘com.jakewharton:butterknife-compiler:8.4.0’
compile ‘com.umeng.analytics:analytics:latest.integration

如果你实在没有找到，该怎么写呢？
第一种：按部就班的照抄，抄格式。
第二种：我就这个包的所有文件都不提示，不混淆了。能拿我怎样？比如下面这个。
我的导入包名为： compile 'com.flyco.tablayout:FlycoTabLayout_Lib:2.0.0@aar'
混淆配置可以写成：
```
#flyco
-dontwarn com.flyco.tablayout.**
-keep class com.flyco.tablaout.**{ *;}
```

与js互调区域
工程中没用到，可不写。
反射相关区域
工程中没用到，可不写。

==================基本不用动区域================
1. 基本指令区域
2. 默认保留区
3. webView
这个区域基本通用，可以照抄。

在proguard-rules.pro中添加如下文件：
