Ant 实现批量打包Android应用
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：
