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：
