主要讲下如何自动构建工具Ant, 对应用进行批量打包, 生成对应不同市场的应用:
首 先分别看一下用于打包的Java工程AntTest和需要被打包进行发布的Android工程结构:
market.txt 里保存需要打包的市场标识,如：
youmeng
gfan
.......
此 文件里自行根据需求添加渠道名称.
然 后看一下实现批量打包AntTest类中的内容:
package com.cn.ant;
import java.io.BufferedReader;

project.init();

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;">// 关键代码</span>
ProjectHelper.configureProject(project, new File(_buildFile));
}
public void runTarget(String _target) throws Exception {
// Test if the project exists
if (project == null)
throw new Exception(
"No target can be launched because the project has not been initialized. Please
call the 'init' method first !");
// If no target is specified, run the default one.
if (_target == null)
_target = project.getDefaultTarget();
// Run the target
project.executeTarget(_target);
}

然后是Android工程中需要进行修改的部分:
1. 修改local.properties中的sdk根目录:
sdk.dir=D:androidandroid-sdk-windows-r17android-sdk-windows-r17
2. 修改ant.properties中签名文件的路径和密码(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
拷贝AndroidManifest.xml一份,命名为AndroidManifest.xml.temp
将需要替换的地方改为占位符,需与打包工程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必须为Android工程名称.
如果机器没有配置过Ant环境变量，可根据如下步骤进行配置:
ANT环境变量设置:
Windows下ANT用到的环境变量主要有2个，ANT_HOME 、PATH。
设置ANT_HOME指向ant的安装目录。
设置方法：
ANT_HOME = D:/apache_ant_1.7.0
将%ANT_HOME%/bin; %ANT_HOME%/lib添加到环境变量的path中。
设置方法：
PATH = %ANT_HOME%/bin; %ANT_HOME%/lib
