用Ant 實現批量打包Android應用

 主要講下如何自動構建工具Ant, 對應用進行批量打包, 產生對應不同市場的應用:

 首先分別看一下用於打包的Java工程AntTest和需要被打包進行發布的Android工程結構:   market.txt裡儲存需要打包的市場標識,如：youmenggfan.......此檔案裡自行根據需求添加渠道名稱. 然後看一下實現批量打包AntTest類中的內容: 

 

package com.cn.ant;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.File;import java.io.FileReader;import java.io.FileWriter;import java.io.IOException;import java.text.SimpleDateFormat;import java.util.Calendar;import org.apache.tools.ant.DefaultLogger;import org.apache.tools.ant.Project;import org.apache.tools.ant.ProjectHelper;public class AntTest {private Project project;public void init(String _buildFile, String _baseDir) throws Exception {project = new Project();project.init();DefaultLogger consoleLogger = new DefaultLogger();consoleLogger.setErrorPrintStream(System.err);consoleLogger.setOutputPrintStream(System.out);consoleLogger.setMessageOutputLevel(Project.MSG_INFO);project.addBuildListener(consoleLogger);// Set the base directory. If none is given, "." is used.if (_baseDir == null)_baseDir = new String(".");project.setBasedir(_baseDir);if (_buildFile == null)_buildFile = new String(projectBasePath + File.separator+ "build.xml");// ProjectHelper.getProjectHelper().parse(project, new// File(_buildFile));<span style="color:#FF0000;">// 關鍵代碼</span>ProjectHelper.configureProject(project, new File(_buildFile));}public void runTarget(String _target) throws Exception {// Test if the project existsif (project == null)throw new Exception("No target can be launched because the project has not been initialized.

然後是Android工程中需要進行修改的部分:

1. 修改local.properties中的sdk根目錄:
sdk.dir=D:androidandroid-sdk-windows-r17android-sdk-windows-r17
2. 修改ant.properties中籤名檔案的路徑和密碼(如果需要)
key.store=D:androidmykeystore
key.store.password=123456
key.alias=mykey
key.alias.password=123456
3. 修改AndroidManifest.xml.temp
拷貝AndroidManifest.xml一份,命名為AndroidManifest.xml.temp
將需要替換的地方改為預留位置,需與打包工程AntTest中的placeHolder常量一致
如： <meta-data android:value="@market@" android:name="UMENG_CHANNEL"/>
4. Build.xml中:
<project name="XXX" default="help">,XXX必須為Android工程名稱.

如果機器沒有配置過Ant環境變數，可根據如下步驟進行配置:

ANT環境變數設定:

Windows下ANT用到的環境變數主要有2個，ANT_HOME 、PATH。

設定ANT_HOME指向ant的安裝目錄。

設定方法：
ANT_HOME = D:/apache_ant_1.7.0

將%ANT_HOME%/bin; %ANT_HOME%/lib添加到環境變數的path中。

設定方法：
PATH = %ANT_HOME%/bin; %ANT_HOME%/lib
