Android 混淆代码总结

标签：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 *;
#}
