Android 混淆代码详解及实例

      为了防止自己的劳动成果被别人窃取,混淆代码能有效防止被反编译,下面来总结以下混淆代码的步骤:

1. 大家也许都注意到新建一个工程会看到项目下边有这样proguard-project.txt一个文件,这个对混淆代码很重要,如果你不小心删掉了,没关系,从其他地方拷贝一个过来

2. 最重要的就是在proguard-project.txt添加混淆的申明了:

a. 把所有你的jar包都申明进来,例如:

-libraryjars libs/apns_1.0.6.jar

-libraryjars libs/armeabi/libBaiduMapSDK_v2_3_1.so

-libraryjars libs/armeabi/liblocSDK4.so

-libraryjars libs/baidumapapi_v2_3_1.jar

-libraryjars libs/core.jar

-libraryjars libs/gesture-imageview.jar

-libraryjars libs/gson-2.0.jar

-libraryjars libs/infogracesound.jar

-libraryjars libs/locSDK_4.0.jar

-libraryjars libs/ormlite-android-4.48.jar

-libraryjars libs/ormlite-core-4.48.jar

-libraryjars libs/universal-image-loader-1.9.0.jar

b. 将你不需要混淆的部分申明进来,因为有些类经过混淆会导致程序编译不通过,如下:

-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 * extends android.support.v4.**

-keep public class com.android.vending.licensing.ILicensingService

--以上都是API里边的类,最好都要避免混淆

有些很特殊的,例如百度地图,你需要添加以下申明:

-keep class com.baidu.** { *; }

-keep class .gdi.bgl.android.**{*;}

根据我的经验,一般model最好避免混淆(model无关紧要,不混淆也没多大关系)如:

-keep class com.bank.pingan.model.** { *; }

下面在贴上关于Umeng分享统计的避免混淆的申明

-dontwarn android.support.v4.**

-dontwarn .**

-dontwarn com.tencent.**

-keepclasseswithmembernames class * {

native ;

}

-keepclasseswithmembernames class * {

public (android.content.Context, android.util.AttributeSet);

}

-keepclasseswithmembernames class * {

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

}

-keepclassmembers enum * {

public static **[] values();

public static ** valueOf(ng.String);

}

-keep class * implements android.os.Parcelable {

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

}

-keepclasseswithmembers class * {

public (android.content.Context);

}

-dontshrink

-dontoptimize

-dontwarn com.google.android.maps.**

-dontwarn android.webkit.WebView

-dontwarn com.umeng.**

-dontwarn com.tencent.weibo.sdk.**

-dontwarn com.facebook.**

-keep enum com.facebook.**

-keepattributes Exceptions,InnerClasses,Signature

-keepattributes *Annotation*

-keepattributes SourceFile,LineNumberTable

-keep public interface com.facebook.**

-keep public interface com.tencent.**

-keep public interface com.umeng.socialize.**

-keep public interface com.umeng.socialize.sensor.**

-keep public interface com.umeng.scrshot.**

-keep public class com.umeng.socialize.* {*;}

-keep public class javax.**

-keep public class android.webkit.**

-keep class com.facebook.**

-keep class com.umeng.scrshot.**

-keep public class com.tencent.** {*;}

-keep class com.umeng.socialize.sensor.**

-keep class com.tencent.mm.sdk.openapi.WXMediaMessage {*;}

-keep class com.tencent.mm.sdk.openapi.** implements com.tencent.mm.sdk.openapi.WXMediaMessage$IMediaObject {*;}

-keep class im.yixin.sdk.api.YXMessage {*;}

-keep class im.yixin.sdk.api.** implements im.yixin.sdk.api.YXMessage$YXMessageData{*;}

-keep public class [your_pkg].R$*{

public static final int *;

}

3.以上工作完成,混淆工作就完成了一大半了,最后需要做的就是在project.properties文件中加上你的混淆文件申明了,如下:

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

4. OK, 最后一步,打签名包测试,如果有问题,仔细看下Log也许有得类不能混淆,那么你得加入到proguard-project.txt文件中

-------以上就是混淆代码的全过程了

最后贴上proguard-project.txt的全部代码:

1. 依赖工程的jar 申明:

以下是邮件发送的实例

-libraryjars ../KlowerBase/libs/mail-activation.jar

-libraryjars ../KlowerBase/libs/mail-additionnal.jar

-libraryjars ../KlowerBase/libs/mail.jar

2. 解决邮件发送时报的以异常
