在離職之際酱讶，也沒有啥事可以做退盯，就自己搗騰下代碼混淆，言歸正傳泻肯。
為了防止自己的勞動成果被別人竊取渊迁，混淆代碼能有效防止被反編譯，下面來總結(jié)以下混淆代碼的步驟：
1. 大家都注意到不管是用Eclipse還是用AS創(chuàng)建的項目在工程中會看到項目下邊有著proguard-project.txt的文件灶挟，這個對混淆代碼很重要琉朽，如果你不小心刪掉了，沒關(guān)系稚铣，從其他地方拷貝一個過來就可以了箱叁；
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(jìn)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(jìn)來惕医，因為有些類經(jīng)過混淆會導(dǎo)致程序編譯不通過耕漱，如下：
-keep public class * extendsandroid.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里邊的類，最好都要避免混淆
有些很特殊的抬伺，例如百度地圖螟够，你需要添加以下申明：
-keep class com.baidu.** { *; }
-keep class vi.com.gdi.bgl.android.**{*;}
根據(jù)我的經(jīng)驗，一般model最好避免混淆（model無關(guān)緊要，不混淆也沒多大關(guān)系）如：
-keep class com.bank.pingan.model.** { *; }
下面在貼上關(guān)于Umeng分享統(tǒng)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.以上工作完成妓笙，混淆工作就完成了一大半了若河，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给郊， 最后一步牡肉，打簽名包測試，如果有問題淆九，仔細(xì)看下Log也許有得類不能混淆统锤，那么你得加入到proguard-project.txt文件中
-------以上就是混淆代碼的全過程了
最后貼上完整的proguard-project.txt 代碼：
