Android--›迁移到AndroidX指南(含包依赖关系)

AndroidX发布已经有段时间了, 相应的包也都出了1.0.0正式版本.

顺势而为, 才能得以生存.

是时候迁移到AndroidX了.

迁移操作本身是很简单的, 有菜单命令一键搞定.如下:

你以为这样就完事了?

还真是…项目妥妥的跑起来了, 还不算完事吗?

如果仅仅是为了跑起项目, 那还真的就完事了.

但是项目中的依赖包还是写的com.android.support:xxx:xxx, 所以要彻底迁移到AndroidX, 请继续往下看.

铲掉所有com.android.support的依赖包

替换到最新的androidx对应的依赖包.

ext.androidx = [
        //com.android.support:support-v4
        "v4"                    : "androidx.legacy:legacy-support-v4:1.0.0",

        //com.android.support:design
        "material"              : "com.google.android.material:material:1.0.0",

        //com.android.support:cardview-v7
        "cardview"              : "androidx.cardview:cardview:1.0.0",

        //androidx only
        "viewpager2"            : "androidx.viewpager2:viewpager2:1.0.0-beta05",
]

我这里列举了一些常用的包. 点击这里查看所有

注意 那个对应关系后的版本, 可能不是最新版本号. 最新版本号点击查看

所有包都替换完之后, 难免会出现重复的依赖包, 这个时候可以查看我的另一篇文章
AS–›Gradle 自动查找依赖版本冲突,强制指定依赖版本号,
可以强制指定版本号

有的时候, 你会发现, 一个包里面包含了另一个包, 这个时候就没必要再引入包了.

我这里列举了常用了依赖包依赖关系:

从上面可以看出
androidx.appcompat:appcompat:1.1.0这个包, 基本上包含了常用的库, 所以大家默认导入这一个库即可, 其他的库按需加载就行.
com.google.android.material:material:1.0.0这个包, 包含了常用的库和常用的UI库, 导入这一个, 啥都有了.

更多的依赖关系, 可以执行命令 gradlew app:dependencies 查看.
