## 迁移到 AndroidX ##

AndroidX 将原始支持库 API 替换为 androidx 命名空间中的软件包。只有软件包和 Maven 工件名称发生了变化；类名、方法名和字段名没有变化。

注意：我们建议在单独的分支中执行迁移。此外，还应设法避免在执行迁移时重构代码。

### 前提条件 ###

执行迁移之前，请先将应用更新到最新版本。 我们建议您将项目更新为使用支持库的最终版本：版本 28.0.0。 这是因为，1.0.0 版本的 AndroidX 工件是与支持库 28.0.0 工件等效的二进制文件。

### 使用 Android Studio 迁移现有项目 ###

使用 Android Studio 3.2 及更高版本，您只需从菜单栏中依次选择 Refactor > Migrate to AndroidX，即可将现有项目迁移到 AndroidX。

重构命令使用两个标记。默认情况下，这两个标记在 gradle.properties 文件中都设为 true：

android.useAndroidX=true

Android 插件会使用对应的 AndroidX 库而非支持库。

android.enableJetifier=true

Android 插件会通过重写现有第三方库的二进制文件，自动将这些库迁移为使用 AndroidX。  
注意：内置的 Android Studio 迁移功能可能并不能完成所有操作。根据您的构建配置，您可能需要手动更新构建脚本和 Proguard 映射。例如，如果您在一个单独的构建文件中维护依赖项配置，请使用下述映射文件来检查依赖项并将其更新为对应的 AndroidX 软件包。

以下是前者是support库，即支持库的中的类映射，后者是对应的androidx下类映射：  
（小技巧：在AS中双击shift，输入replace in path ，点击进行全局替换。）

全部替换完成以后，需要注意的是：  
（1）清除项目缓存数据：每个module下的build文件夹手动删除；  
（2）点击invalidate caches/restart 进行重启AS。
