android 代码混淆总结

default.properties文件加入：

target=android-7

proguard.config=proguard.cfg

以上两句

proguard.cfg 文件：

-optimizationpasses 7

-dontusemixedcaseclassnames

-dontskipnonpubliclibraryclasses

-dontpreverify

-verbose

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-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

<!-- 百度api使用后必须加下面这段 -->

-keep class com.baidu.mapapi.** {*;} 

-keepclasseswithmembernames class * {

    native <methods>;

}

-keepclasseswithmembernames class * {

    public <init>(android.content.Context, android.util.AttributeSet);

}

-keepclasseswithmembernames class * {

    public <init>(android.content.Context, android.util.AttributeSet, int);

}

-keepclassmembers class * extends android.app.Activity {

  public void *(android.view.View);

}

-keepclassmembers enum * {

    public static **[] values();

    public static ** valueOf(java.lang.String);

}

-keep class * implements android.os.Parcelable {

  public static final android.os.Parcelable$Creator *;

}

-keep public class * extends android.view.View {

    public <init>(android.content.Context);

    public <init>(android.content.Context, android.util.AttributeSet);

    public <init>(android.content.Context, android.util.AttributeSet, int);

    public void set*(...);

}

-keepclassmembers class **.R$* {

    public static <fields>;

}

<!-- 序列化后必须使用下面这段 -->

-keepnames class * implements java.io.Serializable

-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();

}

补充一下：

 

-dontwarn com.google.android.gcm.**
-dontwarn net.nend.android.** 
-dontwarn com.google.ads.** 

也可以用这样的方式解决使用第三方包后出现的无法混淆的问题，大概的异常是：

 Note: there were 160 duplicate class definitions.
Warning: com.google.ads.m: can't find referenced class com.google.ads.internal.state.AdState
Warning: com.google.ads.m: can't find referenced class com.google.ads.internal.state.AdState
     You should check if you need to specify additional program jars.
