##################################通过混淆配置#################################
# 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
-dontoptimize

# 混淆时是否记录日志
-verbose
-ignorewarnings

# 保留Annotation不混淆
-keepattributes *Annotation*

# 避免混淆泛型
-keepattributes Signature
-keepattributes Exceptions,InnerClasses

-dontnote com.google.vending.licensing.ILicensingService
-dontnote com.android.vending.licensing.ILicensingService

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

# 重命名抛出异常时的文件名称
-renamesourcefileattribute SourceFile

# 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
#
#############################################

# 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.Application
-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 <methods>;
}

# 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 <init>(android.content.Context);
  public <init>(android.content.Context, android.util.AttributeSet);
  public <init>(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 <fields>;
  !private <fields>;
  !private <methods>;
  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);
