proguard-rules.pro

# 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

# 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
# 指定不去忽略非公共库的类成员
-dontskipnonpubliclibraryclassmembers
# 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
# 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 这在JSON实体映射时非常重要，比如fastJson
-keepattributes *Annotation*
# 避免混淆泛型
-keepattributes Signature
# JS调用Java方法
-keepattributes *JavascriptInterface*
# 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/*
# 忽略警告
-ignorewarnings
# 设置是否允许改变作用域
-allowaccessmodification
# 把混淆类中的方法名也混淆了
-useuniqueclassmembernames
# apk 包内所有 class 的内部结构
-dump class_files.txt
# 未混淆的类和成员
-printseeds seeds_txt
# 列出从apk中删除的代码
-printusage unused.txt
# 混淆前后的映射
-printmapping mapping.txt


# 保持哪些类不被混淆
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends androidx.fragment.app.Fragment
-keep public class * extends android.app.Fragment
-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 com.android.vending.licensing.ILicensingService


# 不能混淆枚举中的value和valueOf方法，因为这两个方法是静态添加到代码中进行，也会被反射使用，所以无法混淆这两种方法。
# 应用使用枚举将添加很多方法，增加了包中的方法数，将增加 dex 的大小。
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

# 保持 native 方法不被混淆
-keepclasseswithmembernames class * {
    native <methods>;
}

# 保持自定义控件类不被混淆
-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);
}

# 保持自定义控件类不被混淆
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

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