Atlas DexPatch调试记录

DexPatch简介

DexPatch是以动态部署技术方案为基础，以快速解决线上故障为唯一目的的动态化方案。

简单来说，动态部署是针对Apk级别的动态升级，DexPatch是针对Bundle级别的动态修复(主dex可以认为是一个Bundle)

打包DexPatch

基于ap所属的版本(1.0.0)

..\gradlew publish

修改Bundle版本

修改Bundle代码，并修改Bundle版本（也可以修改Bundle依赖的某个aar的版本）

group = 'com.atlas.demo'
version = '1.0.1'

指定基线版本，生成dexPatch包

..\gradlew clean assembleDebug -DapVersion=1.0.0 -DversionName=1.0.0

push 1.0.0@1.0.0.tpatch & dexpatch-1.0.0.json

adb push build\outputs\tpatch-debug\dexpatch-1.0.0.json /sdcard/Android/data/com.taobao.demo/cache/
adb push build\outputs\tpatch-debug\1.0.0@1.0.0.tpatch /sdcard/Android/data/com.taobao.demo/cache/
