由于公司运维需要以及应用中需要加上应用推广的统计,往往要对应二三十个渠道,按照正常方法一个一个的去生成不同渠道包的应用,不仅浪费了时间,而且大大降低了效率.
上一篇讲到使用Ant进行Zip/Tar包的解压缩,实际上Ant工具不仅仅具有此类功能,它更强大的地方在于自动化调用程序完成项目的编译,打包,测试等. 类似于C语言中的make脚本完成这些工作的批处理任务. 不同于MakeFile的是,Ant是纯Java编写的,因此具有很好的跨平台性.
在此我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:
注意:红色标注部分需要进行修改:

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:\\android\\android-sdk-windows-r17\\android-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:\\android\\mykeystore
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
