Android之混淆心得与亲身体验

project.properties 中设置

-optimizationpasses 5                           ->设置混淆的压缩比率 0 ~ 7
-dontusemixedcaseclassnames                     -> Aa aA
-dontskipnonpubliclibraryclasses                ->如果应用程序引入的有jar包,并且想混淆jar包里面的class
-dontpreverify
-verbose                                        ->混淆后生产映射文件 map 类名->转化后类名的映射
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*       ->混淆采用的算法.

-keep public class * extends android.app.Activity                         ->所有activity的子类不要去混淆
-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

-dontwarn android.support.v4.**
-dontwarn android.annotation

-libraryjars libs/android-support-v4.jar

-keepclasseswithmembernames class * {            -> 所有native的方法不能去混淆.
native <methods>;
}

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet);            -->某些构造方法不能去混淆
}

-keepclasseswithmembers class * {
public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
public void *(android.view.View);
}
-keepclassmembers enum * {                                -> 枚举类不能去混淆
public static **[] values();
public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {              -> aidl文件不能去混淆.
public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class * {
public <init>(org.json.JSONObject);
}

-keep class android.support.v4.**{*;}
-keepattributes *Annotation*

============================================
对于引用第三方包的情况，可以采用下面方式避免打包出错：
-libraryjars libs/aaa.jar
-dontwarn com.xx.yy.**
-keep class com.xx.yy.** { *;}
