Ant編譯android,並Proguard代碼混淆,v4混淆配置
忙了三四周，總算把購開心的ios版(appStore搜「購開心」)成功翻譯成了android版，UI效果基本保持一致，上一張UI效果圖吧，很養眼的： javascript
還不錯吧，進入正題吧。 html
之前一直是讓我徒弟混淆和打包的，這個就剩下我一我的了，弄了一次，時間過久了，還太麻煩了，因而，我就研究了下ant打包，下面就簡單說下吧： java
首先，作任何開發前，確定是各類環境搭建和配置啊，ant的搭建很簡單： linux
1、安裝ant android
到官方主頁http://ant.apache.org下載新版（目前爲Ant-1.9.2）的ant，獲得的是一個apache-ant-1.8.1-bin.zip的壓縮包。將其解壓到你的硬盤上，例如：D:\Android\apache-ant-1.9.2 ios
2、配置環境變量 web
window中設置ant環境變量： shell
ANT_HOME D:/Android/apache-ant-1.9.2 apache
path D:/Android/apache-ant-1.9.2/bin json
classpath D:/Android/apache-ant-1.9.2/lib
linux中設置ant環境變量：
root用戶登錄,用vi編輯器修改root目錄下的".bash_profile"屬性文件，假設Ant安裝在/user/local/ant目錄下，要在文件的最後加上
"exportANT_HOME=/user/local/ant"和"export PATH=$PATH:$ANT_HOME/bin"
3、驗證ant
爲了驗證ant是否成功安裝，能夠進行以下操做：
依次選擇：開始->運行->cmd，輸入以下命令：ant
若是出現以下內容，說明安裝成功：
Buildfile: build.xml does not exist!
Build failed
固然，JAVA_HOME、ANDROID_SDK_HOME等的配置這裏就不說了
4、咱們就在項目中添加build.xml
code以下：
<?xml version="1.0" encoding="utf-8"?>

</project>
若是不須要混淆代碼，去掉上面的 proguard相關的配置就能夠了
5、配置proguard屬性：
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等開頭的類，都是被我替換的，不是真實的，具體的類包名和類名，以各人本身的爲主。
注意，這個混淆中，開始幾行配置很重要，網上不少同窗問的ant、proguard相關的錯誤（什麼找不到app.android.v4類等），都是由於缺乏這幾行致使，但沒人回答，這裏，我就直接給出了：
-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
這個配置主要是針對 android-support.v4和庫相關的，請須要的同窗注意。
最後的幾行配置，是由於我代碼中調用了asset中js文件致使的，js相關的操做代碼，是不能夠混淆的，故須要避開。
6、運行ant命令，構建開始：
命令行輸入相似： D:/Android/apache-ant-1.9.2/bin/ant.bat -buildfile D:/workspa
ceAndroid/naomiHappyShopping/build.xml
就能夠完成代碼混淆和apk輸出：
.......
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 看看時間，是否是比手動方便多了啊，並且反編譯一看，代碼真的不能再讀了。
另外注意：不一樣人的路徑等配置，須要根據各人本身的來，不能直接拷貝引用。
