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:









1. # To enable ProGuard in your project, edit project.properties
2. # to define the proguard.config property as described in that file.
3. #
4. # Add project specific ProGuard rules here.
5. # By default, the flags in this file are appended to flags specified
6. # in ${sdk.dir}/tools/proguard/proguard-android.txt
7. # You can edit the include path and order by changing the ProGuard
8. # include property in project.properties.
9. #
10. # For more details, see
11. # http://developer.android.com/guide/developing/tools/proguard.html
12.
13. # Add any project specific keep options here:
14.
15. # If your project uses WebView with JS, uncomment the following
16. # and specify the fully qualified class name to the JavaScript interface
17. # class:
18. #-keepclassmembers class fqcn.of.javascript.interface.for.webview {
19. # public *;
