Android 工程在4.0基礎上混淆

Android現在對安全方面要求比較高了，我今天要做的對apk進行混淆，用所有的第三方工具都不能反編譯，作者的知識產權得到保障了，是不是碉堡了。       一，首先說明我這是在4.0基礎上進行的。       先看看project.properties 這個文件。   # This file is automatically generated by Android Tools. # Do not modify this file -- YOUR CHANGES WILL BE ERASED! # # This file must be checked in Version Control Systems. # # To customize properties used by the Ant build system edit # "ant.properties", and override values to adapt the script to your # project structure. # # To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home): # proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt # Project target. target=android-17 #proguard.config=proguard.cfg proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt       先把proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 的注釋去掉。       其實混淆的難點就是項目引進了第三方包，如果沒有引入第三方包，直接把上面的東西注釋掉就可以混淆了，如果引入了第三方包就比較麻煩，請看下面。                   再把第三方包進行添加，注意，一般第三方jar已經混淆過了，所以不能再次混淆。下面是我把第三方jar包過濾掉的操作。一般方在最下面。           這個文件proguard-project.txt       # 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 ${sdk.dir}/tools/proguard/proguard-android.txt # You can edit the include path and order by changing the ProGuard # include property in project.properties. # # For more details, see # http://developer.android.com/guide/developing/tools/proguard.html   # Add any project specific keep options here:   #-keep class packagename.** {*;}   # If your project uses WebView with JS, uncomment the following # and specify the fully qualified class name to the JavaScript interface # class: #-keepclassmembers class fqcn.of.javascript.interface.for.webview { # public *; #} -keepclasseswithmembernames class * { native <methods>; }   -keepclasseswithmembers class * { public <init>(android.content.Context, android.util.AttributeSet); }   -keepclasseswithmembers class * { public <init>(android.content.Context, android.util.AttributeSet, int); }   -keepclassmembers class * extends android.app.Activity { public void *(android.view.View); }   -keepclassmembers enum * { public static **[] values(); public static ** valueOf(java.lang.String); }   -keep class * implements android.os.Parcelable { public static final android.os.Parcelable$Creator *; }   -dontwarn com.umeng.**   -dontwarn org.apache.commons.**   -dontwarn com.tencent.weibo.sdk.**   -keepattributes *Annotation*   -keep class com.umeng*.** {*; }   -keep public class [your_pkg].R$*{ public static final int *; } -keep class com.tencent.open.TDialog$*   -keep class com.tencent.open.TDialog$* {*;}   -keep class com.tencent.open.PKDialog   -keep class com.tencent.open.PKDialog {*;}   -keep class com.tencent.open.PKDialog$*   -keep class com.tencent.open.PKDialog$* {*;}   -keep class com.tencent.mm.sdk.openapi.WXMediaMessage {*;}   -keep class com.tencent.mm.sdk.openapi.** implements com.tencent.mm.sdk.openapi.WXMediaMessage$IMediaObject {*;}       -libraryjars /libs/achartengine-1.1.0.jar -dontwarn achartengine.** -keep class achartengine.** { *;}   -libraryjars /libs/android-support-v4.jar -dontwarn android.support.v4.** -keep class android.support.v4.** { *;}   -libraryjars /libs/jpush-sdk-release1.4.0.jar -dontwarn jpush.sdk.release.** -keep class jpush.sdk.release.** { *;}     -libraryjars /libs/umeng_sdk.jar -dontwarn umeng.sdk.** -keep class umeng.sdk.** { *;}   -libraryjars /libs/umeng_social_sdk.jar -dontwarn umeng.social.sdk.** -keep class umeng.social.sdk.** { *;}   -libraryjars /libs/universal-image-loader.jar -dontwarn universal.image.loader.** -keep class universal.image.loader.** { *;}   -libraryjars /libs/ShareSDK-SinaWeibo-2.1.2.jar -dontwarn cn.sharesdk.sina.weibo.** -keep class cn.sharesdk.sina.weibo.** { *;}   -libraryjars /libs/ShareSDK-TencentWeibo-2.1.2.jar -dontwarn cn.sharesdk.tencent.weibo.** -keep class cn.sharesdk.tencent.weibo.** { *;}   -libraryjars /libs/ShareSDK-Wechat-Moments-2.1.2.jar -dontwarn cn.sharesdk.wechat.moments.** -keep class cn.sharesdk.wechat.moments.** { *;}           這些對應上面的jar包，防止再次混淆。       -braryjars libs/nineoldandroids-2.4.0.jar----指明lib包的在工程中的路徑 而-dontwarn com.xx.bbb.**和-keep class com.xx.bbb.** { ;} 這兩個參數用來保持第三方庫中的類而不亂，將-dontwarn和-keep 結合使用，意思是保持com.xx.bbb.*這個包裡面的所有類和所有方法而不混淆，接著還叫ProGuard不要警告找不到com.xx.bbb.**這個包裡面的類的相關引用。       -libraryjars ..\第三方庫的工程名 -dontwarn  包名.** -keep class 包名.** { *;}     最後打包簽名，成功。
