Android App代码混淆方案

 

一、Android Studio 代码混淆基本配置
在工程目录下，找到 proguard-rules.pro 文件，它就是你要进行编写混淆配置的文件，在这个文件中编写混淆规则

当然，在这之前，还需要在你 module 的 build.gradle 文件中引用该混淆文件：

二、在配置文件中直接添加代码即可

#1.基本指令区
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose
-ignorewarning
-printmapping proguardMapping.txt
-optimizations !code/simplification/cast,!field/*,!class/merging/*
-keepattributes *Annotation*,InnerClasses
-keepattributes Signature
-keepattributes SourceFile,LineNumberTable

#2.默认保留区
-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
-keep class android.support.** {*;}

-keepclasseswithmembernames class * {
    native <methods>;
}
-keepclassmembers class * extends android.app.Activity{
    public void *(android.view.View);
}
-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}
-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);
}
-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>(android.content.Context, android.util.AttributeSet, int);
}
-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}
-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}
-keep class **.R$* {
 *;
}
-keepclassmembers class * {
    void *(**On*Event);
}

#3.webview
-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);
}
