- Android现在对安全方面要求比较高了，我今天要做的对apk进行混淆，用所有的第三方工具都不能反编译，作者的知识产权得到保障了，是不是碉堡了。
一，首先说明我这是在4.0基础上进行的。先看看project.properties 这个文件。# 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=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt# Project target.target=android-17#proguard.config=proguard.cfgproguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt先把proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 的注释去掉。其实混淆的难点就是项目引进了第三方包，如果没有引入第三方包，直接把上面的东西注释掉就可以混淆了，如果引入了第三方包就比较麻烦，请看下面。再把第三方包进行添加，注意，一般第三方jar已经混淆过了，所以不能再次混淆。下面是我把第三方jar包过滤掉的操作。一般方在最下面。这个文件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.** { *;}这些对应上面的jar包，防止再次混淆。-braryjars libs/nineoldandroids-2.4.0.jar----指明lib包的在工程中的路径而-dontwarn com.xx.bbb.**和-keep class com.xx.bbb.** { ;}这两个参数用来保持第三方库中的类而不乱，将-dontwarn和-keep 结合使用，意思是保持com.xx.bbb.*这个包里面的所有类和所有方法而不混淆，接着还叫ProGuard不要警告找不到com.xx.bbb.**这个包里面的类的相关引用。-libraryjars ..\第三方库的工程名-dontwarn 包名.**-keep class 包名.** { *;}最后打包签名，成功。
