前言:
该内容只作为开发笔记,较随意,勿喷~

一、在build.gradle(app)文件中新增以下代码块,目的是开启框架自带的proguard代码混淆机制;

buildTypes {
        release {
            // 不显示Log
            buildConfigField "boolean", "LOG_DEBUG", "false"
            //混淆
            minifyEnabled true
            //Zipalign优化
            zipAlignEnabled true
            // 移除无用的resource文件
            shrinkResources true
            //加载默认混淆配置文件
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
       }
    }

二、在proguard-rules.pro(app)文件中新增以下混淆规则,实际项目中需按照自己项目要求进行混淆,这里只拿我们项目混淆为例~

#不优化输入的class文件,默认情况下是启用优化的
-dontoptimize
#Proguard对你的代码进行迭代优化的次数 0~7,一直优化到代码不能被优化为止
-optimizationpasses 5
#跳过库中非public的类,可以加快proguard处理速度;但是有些类库包含从public类中继承来的非public类。
-skipnonpubliclibraryclasses
#指定不去忽略包可见的库类的成员。
-dontskipnonpubliclibraryclassmembers
#.确定统一的混淆类的成员名称来增加混淆
-useuniqueclassmembernames
#混淆时不会产生形形色色的类名
-dontusemixedcaseclassnames
#混淆前认证,去掉可加快混淆速度
-dontpreverify
#假如项目中有用到注解,保留注解,不混淆
#-keepattributes *Annotation*
#保留所有的v4包中类不被混淆
-keep class android.support.v4.**
#.保留所有的v4包中接口不被混淆
-keep interface android.support.v4.**
#保留系统中继承v4/v7包的类,不被混淆
-keep class android.support.** { *; }
-keep class android.support.v4.** { *; }
-keep public class * extends android.support.v4.**
-keep interface android.support.v4.app.** { *; }
-keep class android.support.v7.** { *; }
-keep public class * extends android.support.v7.**
-keep interface android.support.v7.app.** { *; }
-dontwarn android.support.**
#保留系统中继实现v4/v7包的接口,不被混淆
-keep public class * implements android.support.v4.**
-dontwarn android.support.v4.**
#.所有的native方法不被混淆
-keepclasseswithmembers class * {
    native <methods>;
}
#自定义View构造方法不混淆
-keepclasseswithmembers class * { public <init>(android.content.Context); }
-keepclasseswithmembers class * { public <init>(android.content.Context,android.util.AttributeSet); }
-keepclasseswithmembers class * { public <init>(android.content.Context,android.util.AttributeSet,int); }


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

#保持 Serializable 不被混淆
-keepnames class * implements java.io.Serializable
-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

#xUtils(保持注解,及使用注解的Activity不被混淆,不然会影响Activity中你使用注解相关的代码无法使用)
-keep class * extends java.lang.annotation.Annotation {*;}
-keep class com.otb.designerassist.activity.** {*;}

###-------- pulltorefresh 相关的混淆配置---------
-dontwarn com.handmark.pulltorefresh.library.**
-keep class com.handmark.pulltorefresh.library.** { *;}
-dontwarn com.handmark.pulltorefresh.library.extras.**
-keep class com.handmark.pulltorefresh.library.extras.** { *;}
-dontwarn com.handmark.pulltorefresh.library.internal.**
-keep class com.handmark.pulltorefresh.library.internal.** { *;}


###---------  reservoir 相关的混淆配置-------
-keep class com.anupcowkur.reservoir.** { *;}


###-------- ShareSDK 相关的混淆配置---------
-keep class cn.sharesdk.** { *; }
-keep class com.sina.sso.** { *; }

###--------------umeng 相关的混淆配置-----------
-keep class com.umeng.** { *; }
-keep class com.umeng.analytics.** { *; }
-keep class com.umeng.common.** { *; }
-keep class com.umeng.newxp.** { *; }
