原理使用Android Studio打一次渠道包，用反编译工具反编译后，修改渠道信息重新编译
准备文件
分渠道配置文件：channel.txt ↓
# 多渠道配置里“统计平台”、“市场名称”、“渠道编号”分别代表什么意思？
# 统计平台：即android name,应用中集成的数据分析sdk的公司名称，例：umeng_channel(下拉列表里提供了若干选项);
# 市场名称：各大安卓应用分发市场(下拉列表里提供了Top20的市场供选择)，以帮助开发者区分不同渠道包特征上传相对应市场;
# 渠道编号：即android value，一般填写相关channel id。用户可自行定义区分各大市场的关键字，尽量避免使用特殊字符。

(反编译+对齐+签名)文件：↓
// 可以在Android SDK目录里面找到D:\Android\sdk\build-tools\30.0.3\lib
apksigner.jar
// Mac就找【zipalign】，windows就找【zipalign.exe】
zipalign
zipalign.exe
// 官网：下载Apktool官网
apktool_2.9.3.jar
app build.gradle文件中这样配置
下面需要自己自行调整
