Android自身可以实现代码的混淆功能,Android集成了代码混淆的功能,这些功能在Android SDK的tools有个proguard目录,这个目录下就是提供了Andoid代码的混淆功能,我们只需要在Android项目中进行简单的配置即可。最初的配置文件为proguard.cfg文件,后来adt升级以后,文件改为了proguard-project.txt,所以,这里,我们以两种方式来讲解如何进行代码混淆 方式一、配置文件为proguard.cfg1、proguard.cfg文件创建Android项目之后,在Android项目根目录下有个proguard.cfg文件,这个文件中就是描述了Android的混淆配置。 具体如下: -optimizationpasses 5-dontusemixedcaseclassnames-dontskipnonpubliclibraryclasses-dontpreverify-verbose-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*-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 com.android.vending.licensing.ILicensingService-keepclasseswithmembernames class * { native 2、project.properties文件这个文件是整个项目的环境配置文件,我们只需要在这个文件中指定代码混淆的配置即可。只需要在代码中加入一行配置 proguard.config=proguard.cfg 如下图: 这样就实现了代码的混淆功能 方式二、配置文件为proguard-project.txt1、proguard-project.txt文件这个时候,项目生成的是proguard-project.txt 如下代码所示: # 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 ${sdk.dir}/tools/proguard/proguard-android.txt# You can edit the include path and order by changing the ProGuard# include property in project.properties.## For more details, see# http://developer./guide/developing/tools/proguard.html# Add any project specific keep options here:# If your project uses WebView with JS, uncomment the following# and specify the fully qualified class name to the JavaScript interface# class:#-keepclassmembers class fqcn.of.javascript.interface.for.webview {# public *;#} 2、project.properties在这个文件中需要我们指定sdk的安装路径sdk.dir,然后再指定proguard的配置proguard.config,我自己sdk的目录是E:\android\adt-bundle-windows-x86_64-20131030\sdk,所以,我在project.properties文件中新增的两项配置是 sdk.dir=E:\android\adt-bundle-windows-x86_64-20131030\sdkproguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt 具体如下图所示: 总结:两种方式都只是通过配置project.properties文件实现代码混淆的。 |
