采用python进行Android的多渠道打包

背景

背景就是假如有一个.apk安装包，没有源码，不能改里面的代码，但是知道里面的渠道配置是采用的友盟的方式，在androidManifest里面配置的渠道号，问如何才能用脚本实现多渠道打包。

多渠道打包的两种实现方式

1.美团的方案

目前网上流行的都是美团的解决方案，读取配置文件然后在META-INF目录下新建一个空文件，文件名就是渠道号，然后改java代码去获取文件名字，并设置渠道号，这种方案随便一搜一大堆介绍文章，但是并不适合我司的需求，所以这里就不详细描述拉。

2.直接粗暴的方案

哈哈，到底有多粗暴多直接呢，就是反编译apk,然后修改androidManifest里面的

<meta-data android:name="UMENG_CHANNEL" android:value="suibian" /> 

再重新打包出来，是不是简单粗暴直接，就是貌似实现起来有点麻烦。
那就阿西吧，直接上代码吧，你们需要python环境，需要apktool.exe工具，然后就可以愉快的跑起来了。
