Android混淆-基本混淆模板+自定义混淆类NotProguard

proguard-rules.pro - 第三方就增加了一个glide+rxjava+retrofit，别的按需添加即可

# Add project specific ProGuard rules here.
# You can control the set of applied configuration files using the
# proguardFiles setting in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

# Uncomment this to preserve the line number information for
# debugging stack traces.
#-keepattributes SourceFile,LineNumberTable

# If you keep the line number information, uncomment this to
# hide the original source file name.
#-renamesourcefileattribute SourceFile
#############################################
#
# 对于一些基本指令的添加
#
#############################################
# 代码混淆压缩比，在0~7之间，默认为5，一般不做修改
-optimizationpasses 5

# 混合时不使用大小写混合，混合后的类名为小写
-dontusemixedcaseclassnames

# 指定不去忽略非公共库的类
-dontskipnonpubliclibraryclasses

# 这句话能够使我们的项目混淆后产生映射文件
# 包含有类名->混淆后类名的映射关系
-verbose

# 指定不去忽略非公共库的类成员
-dontskipnonpubliclibraryclassmembers

# 不做预校验，preverify是proguard的四个步骤之一，Android不需要preverify，去掉这一步能够加快混淆速度。
-dontpreverify

# 保留Annotation不混淆
-keepattributes *Annotation*,InnerClasses

# 避免混淆泛型
-keepattributes Signature

# 抛出异常时保留代码行号
-keepattributes SourceFile,LineNumberTable

# 指定混淆是采用的算法，后面的参数是一个过滤器
# 这个过滤器是谷歌推荐的算法，一般不做更改
-optimizations !code/simplification/cast,!field/*,!class/merging/*

# Android开发中一些需要保留的公共部分 start
#
#############################################

# 保留我们使用的四大组件，自定义的Application等等这些类不被混淆
# 因为这些子类都有可能被外部调用
-keep public class * extends android.app.Activity
-keep public class * extends android.app.Appliction
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class * extends android.view.View
-keep public class com.android.vending.licensing.ILicensingService

# 保留support下的所有类及其内部类
-keep class android.support.** {*;}

# 保留继承的
-keep public class * extends android.support.v4.**
-keep public class * extends android.support.v7.**
-keep public class * extends android.support.annotation.**

# 保留R下面的资源
-keep class **.R$* {*;}

# 保留本地native方法不被混淆
-keepclasseswithmembernames class * {
    native ;
}

# 保留在Activity中的方法参数是view的方法，
# 这样以来我们在layout中写的onClick就不会被影响
-keepclassmembers class * extends android.app.Activity{
    public void *(android.view.View);
}

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

# 保留我们自定义控件（继承自View）不被混淆
-keep public class * extends android.view.View{
    *** get*();
    void set*(***);
    public (android.content.Context);
    public (android.content.Context, android.util.AttributeSet);
    public (android.content.Context, android.util.AttributeSet, int);
}

# 保留Parcelable序列化类不被混淆
-keep class * implements android.os.Parcelable {
    public static final android.os.Parcelable$Creator *;
}

# 保留Serializable序列化的类不被混淆
-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    !static !transient ;
    !private ;
    !private ;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

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

# webView处理，项目中没有使用到webView忽略即可
-keepclassmembers class fqcn.of.javascript.interface.for.webview {
    public *;
}
-keepclassmembers class * extends android.webkit.webViewClient {
    public void *(android.webkit.WebView, java.lang.String, android.graphics.Bitmap);
    public boolean *(android.webkit.WebView, java.lang.String);
}
-keepclassmembers class * extends android.webkit.webViewClient {
    public void *(android.webkit.webView, jav.lang.String);
}
-keepclassmembers class com.lieyunwang.finance.activity.InfoNewDetailActivity.InJavaScriptLocalObj{
    public *;
}
-keepattributes *JavascriptInterface*

-keepclassmembers class * {
   public  (org.json.JSONObject);
}

-keep public class com.xxx.xxx.R$*{
public static final int *;
}

# 自定义类的混淆
# keep annotated by NotProguard  ---- like this: keep class com.example.test.xxxBean {*;}
#                                ---- like this: keep class com.example.test.** {*;}
# 下面这块主要针对实体类处理，后面如果有地方需要添加一些不被混淆的变量，函数都可以通过添加@NotProguard来注解
# com.xxx.xxx修改为实际的包名
-keep @com.xxx.xxx.anotation.NotProguard class * {*;}
-keep class * {
@com.xxx.xxx.anotation.NotProguard ;
}
-keepclassmembers class * {
@com.xxx.xxx.anotation.NotProguard ;
}

# Tablayout反射修改下划线宽度导致的tabtrip空指针问题 - 需要可打开
#-keep class android.support.design.widget.TabLayout{*;}

#（可选）避免Log打印输出
-assumenosideeffects class android.util.Log {
   public static *** v(...);
   public static *** d(...);
   public static *** i(...);
   public static *** w(...);
 }

下面给出 NotProguard.java

package com.xxx.xxx.anotation;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * Created by hl on 2018/4/1.
 */

/**
 * NotProguard, Means not proguard something, like class, method, field

 */
@Retention(RetentionPolicy.CLASS)
@Target({ElementType.TYPE, ElementType.METHOD, ElementType.CONSTRUCTOR, ElementType.FIELD})
public @interface NotProguard {
}

以上基本够用了，有问题再解决就好...

NotProguard.java 用法举例：

比如实体类 UserInfoBean.java - 内部类也需要混淆

@NotProguard
public class UserInfoBean { 
  private User user;

  @NotProguard
  public static class User{
  }
}
