 　　Android 混淆代碼詳解及實例

        為了防止自己的勞動成果被別人竊取，混淆代碼能有效防止被反編譯，下面來總結以下混淆代碼的步驟：

　　1. 大家也許都注意到新建一個工程會看到項目下邊有這樣proguard-project.txt一個文件，這個對混淆代碼很重要，如果你不小心刪掉了，沒關系，從其他地方拷貝一個過來

　　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包都申明進來，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. 將你不需要混淆的部分申明進來，因為有些類經過混淆會導致程序編譯不通過，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裡邊的類，最好都要避免混淆

　　有些很特殊的，例如百度地圖，你需要添加以下申明：

　　-keep class com.baidu.** { *; }

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

　　根據我的經驗，一般model最好避免混淆(model無關緊要，不混淆也沒多大關系)如：

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

　　下面在貼上關於Umeng分享統計的避免混淆的申明

　　-dontwarn android.support.v4.**

　　-dontwarn org.apache.commons.net.**

　　-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(java.lang.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，最後需要做的就是在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， 最後一步，打簽名包測試，如果有問題，仔細看下Log也許有得類不能混淆，那麼你得加入到proguard-project.txt文件中

　　-------以上就是混淆代碼的全過程了

　　最後貼上proguard-project.txt的全部代碼：
