AndroidX迁移——弃用support库指南

前言
在Google I/O 2018上，Android团队宣布了AndroidX。它是Android团队用于在Jetpack中开发，测试，打包，版本和发布库的开源项目。与support库一样，每个AndroidX库都与Android操作系统分开提供，并提供跨Android版本的向后兼容性。
androidx 是对 android.support.xxx 包和其他google android支持库整理后的产物。由于之前的support包过于混乱，所以，google推出了 AndroidX。自support v7:28开始，大部分support包都会迁移到androidx下，所以建议开发者们尽早将项目转移到androidx下。
迁移步骤
1.先备份项目！
2.使用Android Studio自动迁移
在菜单栏中依次进入Refactor > Migrate to AndroidX，之后as会提示备份项目，如果已备份就不用勾选备份选项。
迁移完成之后，gradle.properties里会多出这两行
android.useAndroidX=trueandroid.enableJetifier=true如果你的项目中没有使用任何三方依赖，那么android.enableJetifier可以设置为false
3. 旧依赖包名与新包名对照表（建议使用Ctrl + F搜索）
执行Migrate to AndroidX完成之后，虽然常用的support包都会被转成对应的androidx里的包名，gradle或者maven里的部分依赖但还是有可能会未能转换成功，这时候需要我们手动修改。转载请注明出处，本文来自https://blog.csdn.net/yin_ol/article/details/89421390
