【我的Android进阶之旅】Android 混淆文件资源分类整理

之前将所有的混淆都配置在一个 proguard-rules.pro 这个Android Studio新建项目时自动生成的文件里面，而随着项目功能迭代越来越多，代码量越来越多，引用的第二方库、第三方库都越来越多，导致proguard-rules.pro 越来越臃肿，而且随着开发人员增多导致proguard-rules.pro 文件里面的配置越来越混乱。

一、拆分proguard-rules.pro混淆文件

因此今天我将proguard-rules.pro混淆文件进行拆分整理，大概拆分为以下4个文件：第三方混淆文件、第二份混淆文件、系统默认混淆文件、module单独混淆文件 。

如上图所示，四个文件分别为 'proguard-system-common.pro', 'proguard-module.pro', 'proguard-second-party.pro', 'proguard-third-party.pro'

二、配置混淆时候 proguardFiles 所引用的混淆文件

原来的混淆文件配置代码如下：

//混淆文件
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro',

改为下面的将四个混淆文件都加入到混淆配置文件列表中

 //混淆文件
 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-system-common.pro', 'proguard-module.pro', 'proguard-second-party.pro', 'proguard-third-party.pro'

如下图所示：

三、四个拆分的混淆文件具体代码

proguard-system-common.pro

proguard-system-common.pro 是Android系统通用的一些混淆配置，配置的内容大致如下：

# 指定代码的压缩级别
-optimizationpasses 5

-ignorewarnings # 抑制警告
-verbose    # 混淆时是否记录日志（混淆后生产映射文件 map 类名 -> 转化后类名的映射
-dontpreverify # 不预校验
-dontoptimize #不优化输入的类文件
-dontshrink #该选项 表示 不启用压缩  混淆时是否做预校验（可去掉加快混淆速度）

-dontusemixedcaseclassnames # 混淆时不会产生形形色色的类名  是否使用大小写混合
-dontskipnonpubliclibraryclasses #不跳过(混淆) jars中的 非public classes   默认选项

-keepattributes Exceptions # 解决AGPBI警告
-keepattributes Exceptions,InnerClasses,...
-keepattributes EnclosingMethod
-keepattributes SourceFile,LineNumberTable #运行抛出异常时保留代码行号
#过滤泛型
-keepattributes Signature
#过滤注解
-keepattributes *Annotation*
-keep class * extends java.lang.annotation.Annotation { *; }
-keep interface * extends java.lang.annotation.Annotation { *; }

#继承自activity,application,service,broadcastReceiver,contentprovider....不进行混淆
-keep public class * extends android.app.Fragment
-keep public class * extends android.app.Activity

-keep public class * extends android.preference.Preference
-keep public class * extends android.support.v4.**
-keep public class com.android.vending.licensing.ILicensingService
-keep public class * extends android.support.multidex.MultiDexApplication
-keep public class * extends android.view.View
-keep class android.support.** {*;}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

# 所有View的子类及其子类的get、set方法都不进行混淆
-keep public class * extends android.view.View {  #保持自定义控件指定规则的方法不被混淆
    *** get*();
    void set*(***);
    public <init>(android.content.Context);
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

#保持指定规则的方法不被混淆（Android layout 布局文件中为控件配置的onClick方法不能混淆）
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# 对于带有回调函数onXXEvent的，不能被混淆
-keepclassmembers class * {
    void *(*Event);
}

 #保持R文件不被混淆，否则，你的反射是获取不到资源id的
-keep class **.R$* { *; }
# 不混淆R类里及其所有内部static类中的所有static变量字段，$是用来分割内嵌类与其母体的标志
-keep public class **.R$*{
   public static final int *;
}
-keepclassmembers class **.R$* {
    public static <fields>;
}

#过滤js
-keepattributes *JavascriptInterface*
#保护WebView对HTML页面的API不被混淆
-keep class **.Webview2JsInterface { *; }
-keepclassmembers class * extends android.webkit.WebViewClient {  #如果你的项目中用到了webview的复杂操作 ，最好加入
     public void *(android.webkit.WebView,java.lang.String,android.graphics.Bitmap);
     public boolean *(android.webkit.WebView,java.lang.String);
}
-keepclassmembers class * extends android.webkit.WebChromeClient {  #如果你的项目中用到了webview的复杂操作 ，最好加入
     public void *(android.webkit.WebView,java.lang.String);
}
#对WebView的简单说明下：经过实战检验,做腾讯QQ登录，如果引用他们提供的jar，若不加防止WebChromeClient混淆的代码，oauth认证无法回调，
#反编译基代码后可看到他们有用到WebChromeClient，加入此代码即可。

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);  #保持自定义控件类不被混淆，指定格式的构造方法不去混淆
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

# 保持枚举 enum 类不被混淆
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

# 保持 native 方法不被混淆
-keepclasseswithmembernames class * {

}

# 保持 Parcelable 不被混淆
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

#-keep public class * {
#    public protected *;
#}

#需要序列化和反序列化的类不能被混淆（注：Java反射用到的类也不能被混淆）
-keep public class * implements java.io.Serializable {
        public *;
}

#不混淆Serializable接口的子类中指定的某些成员变量和方法
-keepclassmembers class * implements java.io.Serializable {

    private static final java.io.ObjectStreamField[] serialPersistentFields;
    !static !transient <fields>;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();

一个可以快速生成对应第三方库的链接：http://proguard.herokuapp.com/

打开连接：http://proguard.herokuapp.com/

输入第三方库的名字，如下所示：

输入完后，点击Generate按钮，即可自动生成相应的混淆代码，如下所示：

# If in your rest service interface you use methods with Callback argument.

# If your rest service methods throw custom exceptions, because you've defined an ErrorHandler.
-keepattributes Signature

# Also you must note that if you are using GSON for conversion from JSON to POJO representation, you must ignore those POJO classes from being obfuscated.
# Here include the POJO's that have you have created for mapping JSON response to POJO for example.

proguard-second-party.pro

proguard-second-party.pro 是我们自己开发的一些存在Maven私服的AAR库的混淆配置

# themeLib
-keep class com.xxx.theme.**{*;}
-dontwarn com.xxx.theme.**

-keep class com.xxx.md5.** {*;}

-keep class com.xxx.widget.**{*;}
-dontwarn com.xxx.widget.**

-keep class com.xxx.http.**{*;}

proguard-module.pro

其中 proguard-module.pro 文件是你们自己模块的单独混淆文件，主要配置下你们项目中所引用到的一些网络和数据库的bean，防止json解析的时候出现解析出null的情况

#所有jackson对应实体类不能混淆
-keep class com.netease.cloudmusic.net.bean.** {*;}
#数据库实体类
-keep class com.netease.cloudmusic.dao.bean.** {*;}
