Android 混淆代码总结

    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 vi.com.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 org.apache.commons.net.**
    -dontwarn com.tencent.**
    
    -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 enum * {
     public static **[] values();
     public static ** valueOf(java.lang.String);
    }
    
    -keep class * implements android.os.Parcelable {
     public static final android.os.Parcelable$Creator *;
     }
    
    -keepclasseswithmembers class * {
     public <init>(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:

    # To enable ProGuard in your project, edit project.properties
    # to define the proguard.config property as described in that file.
    #
    # Add project specific ProGuard rules here.
    # By default, the flags in this file are appended to flags specified
    # in ${sdk.dir}/tools/proguard/proguard-android.txt
    # You can edit the include path and order by changing the ProGuard
    # include property in project.properties.
    #
    # For more details, see
    # http://developer.android.com/guide/developing/tools/proguard.html
    
    # Add any project specific keep options here:
    
    # 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 *;
    #}
