Android 混淆代碼詳解及執行個體_Android

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. 大家也許都注意到建立一個工程會看到項目下邊有這樣proguard-project.txt一個檔案，這個對混淆代碼很重要，如果你不小心刪掉了，沒關係，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式編譯不通過，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，不混淆也沒多大關係）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 <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，最後需要做的就是在project.properties檔案中加上你的混淆檔案申明了，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檔案中

-------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：

# 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 *; #} -optimizationpasses 5 -dontusemixedcaseclassnames -dontskipnonpubliclibraryclasses -dontpreverify -verbose -optimizations !code/simplification/arithmetic,!field/*,!class/merging/*  -keepattributes *Annotation* -keepattributes Signature  -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  -keep class com.baidu.** { *; }  -keep class vi.com.gdi.bgl.android.**{*;}  -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  -keep class com.google.gson.stream.** { *; } -keep class com.google.gson.examples.android.model.** { *; } -keep class com.uuhelper.Application.** { *; } -keep class net.sourceforge.zbar.** { *; } -keep class com.google.android.gms.** { *; }   -keep class com.bank.pingan.model.** { *; }  -keep public class * extends com.j256.ormlite.android.apptools.OrmLiteSqliteOpenHelper -keep public class * extends com.j256.ormlite.android.apptools.OpenHelperManager   -keep class com.android.vending.licensing.ILicensingService -keep class android.support.v4.** { *; }  -keep class org.apache.commons.net.** { *; }  -keep class com.tencent.** { *; }    -keep class com.umeng.** { *; }  -keep class com.umeng.analytics.** { *; }  -keep class com.umeng.common.** { *; }  -keep class com.umeng.newxp.** { *; }    -keep class com.j256.ormlite.** { *; }  -keep class com.j256.ormlite.android.** { *; }  -keep class com.j256.ormlite.field.** { *; }  -keep class com.j256.ormlite.stmt.** { *; }   -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 *; }

1. 依賴工程的jar 申明： 

以下是郵件發送的執行個體 

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

2. 解決郵件發送時報的以異常 

 -keep class javax.mail.**{*;}  -keep class com.sun.mail.**{*;} -keep class javax.activation.**{*;} -keep class org.apache.harmony.**{*;} -keep class java.security.**{*;} 

#解決：can't find referenced class java.beans.Beans -dontwarn org.apache.commons.collections.BeanMap -dontwarn java.beans.** #解決：can't find referenced class javax.security.sasl.Sasl -dontwarn com.sun.mail.imap.protocol.**
