android上传应用程序，需要区分各个信道。

通常更改配置文件中的一个通道id,假设有多个通道，手动更改并生成apk这将是非常麻烦的，及增加误差的概率。

在这个课堂上分享一个打包工具。也可在网上类似的。我是做IT优化的基础上，，特别是封装so文件，一句小小的命令废了好大劲。

我们项目中使用的umeng做统计分析工具。 umeng在分渠道打包的时候须要改动manifest.xml中的

<meta-data  android:name="UMENG_CHANNEL" android:value="@string/channel_name" />  value值。

该值放到了strings.xml中<string name="channel_name">app_channel</string>,所以在编译的时候仅仅需改动app_channel。

以下是工具类，直接执行就可以.
