 1 | # MigrateToAndroidX
 2 | 
 3 | 用于帮助迁移到AndroidX。
 4 | 
 5 | ## 前言
 6 | 通过Android Studio提供的Migrate to AndroidX功能并不能很好地处理所有文件，所以才有了此脚本。原理：通过Android官方网站提供的类映射关系，扫描工程中所有文件进行替换。
 7 | 
 8 | ## 使用
 9 | 
10 | 在gradle.properties文件中添加以下属性：
11 | ```
12 | android.useAndroidX=true //表示启用androidx
13 | android.enableJetifier=true //会对依赖库进行迁移
14 | ```
15 | 对工程进行Sync确保依赖库已经改为androidx。
16 | 
17 | 打开终端在工程根目录执行以下命令：
18 | ```
19 | git clone git@github.com:yuweiguocn/MigrateToAndroidX.git
20 | python MigrateToAndroidX/migrate.py
21 | ```
22 | 运行结果：
23 | 
24 | ![](./result.png)
25 | 
26 | ## 不支持
27 | 
28 | - 不支持依赖替换
29 | - 不支持多行导包替换
