参考学习:Android 混淆解析
关于proguard，你需要知道的全部

#代码混淆的压缩比例，值在0-7之间 Android通常为5
-optimizationpasses 5
#混淆后类名都为小写
-dontusemixedcaseclassnames
#指定不去忽略非公共的库类
-dontskipnonpubliclibraryclasses
#指定不去忽略包可见的库类的成员
-dontskipnonpubliclibraryclassmembers
#不优化指定的文件与不做预校验的操作
-dontoptimize
-dontpreverify
#生成原类名和混淆后的类名的映射文件
-verbose
-printmapping priguardMapping.txt
#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/artithmetic,!field/*,!class/merging/*
#抛出异常时保留代码行号
-keepattributes SourceFile,LineNumberTable
################common###############
#指定使用了Keep注解的类和类成员都不被改变
-keep @android.support.annotation.Keep class * {*;}
#框架中的配置类不混淆，能在manifests中meta配置的都不能混淆
#使用Gson时需要配置Gson的解析对象及变量都不混淆。不然Gson会找不到变量。
#实体类不参与混淆
#自定义控件不参与混淆
-keep class com.hxw.wanandroid.widget.** { *; }
-keep class com.hxw.wanandroid.entity.** { *; }
-keep class com.hxw.wanandroid.update.UpdateItem{ *; }
#如果要保留一个类中的内部类不被混淆则需要用$符号
#$指向内部类，但不指向本类，所以不写上面的那句的话本类还是会被混淆的
-keep class com.app.modou.imc.update.UpdateItem$* { *; }
#以上需要改成自己的包
#静态内部类不混淆
-keepattributes InnerClasses
#泛型，解决出现类型转换错误的问题
-keepattributes Signature
#注解不混淆
-keepattributes *Annotation*
-keep class * extends java.lang.annotation.Annotation {*;}
#保持 Parcelable 不被混淆（aidl文件不能去混淆
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}
#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）
-keepnames class * implements java.io.Serializable
#保护实现接口Serializable的类中，指定规则的类成员不被混淆
-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    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();
}
#保留R下面的资源
-keep class **.R$* {*;}
-keepclassmembers class **.R$* {
    public static <fields>;
}
#下面这行代码是 忽略警告，避免打包时某些警告出现
-ignorewarnings
#使用enum类型时需要注意避免以下两个方法混淆，因为enum类的特殊性，以下两个方法会被反射调用
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
#jni方法不可混淆，因为这个方法需要和native方法保持一致
#保持native方法不被混淆
-keepclasseswithmembernames class * {
    native <methods>;
}
# 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);
}
# 保留support下的所有类及其内部类
-keep class android.support.** { *; }
-keep interface android.support.** { *; }
-dontwarn 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
