【移动热修复】Sophix关于Utils依赖包注意事项有哪些？

什么是 Utils SDK？Utils为阿里云移动云各产品SDK的公共依赖包，包含基础功能和公共功能模块的实现。Utils SDK接口会被各阿里云SDK产品调用，用户集成时不会直接调用其接口。

Sophix热修复中所依赖的Utils包版本最低需要为1.0.3。

如使用了多个阿里云SDK产品，导致重复依赖多个Utils SDK，必须只保留某个产品中的最高版本的Utils包，同时删除其他产品中的Utils包。远程依赖时使用exclude(module:’alicloud-android-utils’)进行删除。

如最终保留的Utils包是1.1.1或以上版本（热修复最新版本包含的是1.1.3版本），需要注意：

远程依赖时，可能直接携带了ut的一个依赖包，这时如果出现冲突，可添加exclude(module:’alicloud-android-ut’)进行过滤，但是这样过滤后，utdid包也会同时移除掉，需要查看项目的所有阿里系依赖，最后只保留一份1.1.5.3版本以上的utdid包。

本地依赖时，或远程依赖时添加exclude(module:’alicloud-android-ut’)进行过滤后，混淆开启后打包生成apk时可能报如下错误：

或者可能报如下错误：

如出现以上两种报错，或类似Warning:com.alibaba.sdk.android.utils.**的报错，在混淆规则中添加-dontwarn com.alibaba.sdk.android.utils.**即可解决。
