Ant编译android,并Proguard代码混淆,v4混淆配置
忙了三四周，总算把购开心的ios版(appStore搜“购开心”)成功翻译成了android版，UI效果基本保持一致，上一张UI效果图吧，很养眼的：
还不错吧，进入正题吧。
以前一直是让我徒弟混淆和打包的，这个就剩下我一个人了，弄了一次，时间太久了，还太麻烦了，于是，我就研究了下ant打包，下面就简单说下吧：
首先，做任何开发前，肯定是各种环境搭建和配置啊，ant的搭建很简单：
一、安装ant
到官方主页http://ant.apache.org下载新版（目前为Ant-1.9.2）的ant，得到的是一个apache-ant-1.8.1-bin.zip的压缩包。将其解压到你的硬盘上，例如：D:\Android\apache-ant-1.9.2
二、配置环境变量
window中设置ant环境变量：
ANT_HOME D:/Android/apache-ant-1.9.2
path D:/Android/apache-ant-1.9.2/bin
classpath D:/Android/apache-ant-1.9.2/lib
linux中设置ant环境变量：
root用户登陆,用vi编辑器修改root目录下的".bash_profile"属性文件，假设Ant安装在/user/local/ant目录下，要在文件的最后加上
"exportANT_HOME=/user/local/ant"和"export PATH=$PATH:$ANT_HOME/bin"
三、验证ant
为了验证ant是否成功安装，可以进行如下操作：
依次选择：开始->运行->cmd，输入如下命令：ant
如果出现如下内容，说明安装成功：
Buildfile: build.xml does not exist!
Build failed
当然，JAVA_HOME、ANDROID_SDK_HOME等的配置这里就不说了
四、我们就在项目中添加build.xml
code如下：
<?xml version="1.0" encoding="utf-8"?>

<delete file="${dex-ospath}" />
<delete file="${resources-package-ospath}" />
<delete file="${outdir-bin}" />
<echo>
</echo>
</target>
</project>
如果不需要混淆代码，去掉上面的 proguard相关的配置就可以了
五、配置proguard属性：
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:
# 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 *;
#}
-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontskipnonpubliclibraryclasses
-dontpreverify
-libraryjars libs/android-support-v4.jar
-libraryjars libs/core.jar
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-dontwarn android.support.v4.**
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class com.actionbarsherlock.** { *; }
-keep interface com.actionbarsherlock.** { *; }
-keepattributes *Annotation*
-keep public class * extends android.app.Activity
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.support.v4.app.FragmentActivity
-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 blockcheng.BssicAct
-keep public class * extends blockcheng.controller.BCFragment
-keep public class com.android.vending.licensing.ILicensingService
-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);
}
-keepclassmembers class * {
public <init>(org.json.JSONObject);
}
-keep public class blockcheng.R$*{
public static final int *;
}
-keep public class blockcheng.controller.BlockchengClass.JavaScriptInterface {
public <methods>;
}
-keepnames class blockcheng.controller.BlockchengClass$* {
public <fields>;
public <methods>;
}
-keepnames class blockcheng.controller.BlockchengClass$* {
public <fields>;
public void showContacts();
}
上面的配置中，blockcheng、BC等开头的类，都是被我替换的，不是真实的，具体的类包名和类名，以各人自己的为主。
注意，这个混淆中，开始几行配置很重要，网上很多同学问的ant、proguard相关的错误（什么找不到app.android.v4类等），都是因为缺少这几行导致，但没人回答，这里，我就直接给出了：
-libraryjars libs/android-support-v4.jar
-libraryjars libs/core.jar
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*
-dontwarn android.support.v4.**
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-keep class com.actionbarsherlock.** { *; }
-keep interface com.actionbarsherlock.** { *; }
-keepattributes *Annotation*
-keep public class * extends android.app.Activity
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.support.v4.app.FragmentActivity
这个配置主要是针对 android-support.v4和库相关的，请需要的同学注意。
最后的几行配置，是因为我代码中调用了asset中js文件导致的，js相关的操作代码，是不可以混淆的，故需要避开。
六、运行ant命令，构建开始：
命令行输入类似： D:/Android/apache-ant-1.9.2/bin/ant.bat -buildfile D:/workspa
ceAndroid/naomiHappyShopping/build.xml
就可以完成代码混淆和apk输出：
.......
release:
[echo]
[echo] delete unsigned apk
[echo]
[delete] Deleting: D:\workspaceAndroid\naomiHappyShopping\bin\HappyShoppingAn
t-unsigned.apk
[echo]
[echo] copy apk from D:\workspaceAndroid\naomiHappyShopping
/bin/HappyShoppingAnt.apk to D:/workspaceAndroid/Release/happyShopping.apk
[echo]
[copy] Copying 1 file to D:\workspaceAndroid\Release
[echo]
[echo] clean the workspace bin folder....
[echo]
[delete] Deleting directory D:\workspaceAndroid\naomiHappyShopping\bin
[echo]
[echo]
BUILD SUCCESSFUL
Total time: 41 seconds 看看时间，是不是比手动方便多了啊，而且反编译一看，代码真的不能再读了。
另外注意：不同人的路径等配置，需要根据各人自己的来，不能直接拷贝引用。
