support 转 androidx package关系映射
Google为了方便升级插件以及兼容性，Jetpack等一系列功能，对原有的support包进行了升级全面的重构到androidx。
下面是官网给出的对应的转换关系，目前使用中上有一些问题，建议大家等待一段时间在正式中使用，但不影响提前学习和掌握。
使用方式：
在Android 项目gradle.properties文件中添加如下配置：
第一：
android.useAndroidX=true // 当前项目使用AndroidX提换support
android.enableJetifier=true // 当前项目引用的第三方库使用AndroidX提换support
第二：
在Android 项目build.gradle文件中的
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
defaultConfig {
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
替换成： ** testInstrumentationRunner “androidx.test.runner.AndroidJUnitRunner”**
defaultConfig {
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
第三：
替换androidx 依赖
