AndroidX Test and Android OS Versions

androidx.test.espresso:espresso-core:3.1.0 and N/A

Link to a public git repo demonstrating the problem:

https://android.googlesource.com/platform/frameworks/support/+/androidx-master-dev
it can be reproduced in androidx project

This is happening because both androidx.test:runner:1.2.0, androidx.test:monitor:1.2.0 have the same package set in their AndroidManifest.xml inside the AAR

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="androidx.test" >

You can reach out to studio what that is a bad idea, but mostly collision for things like R.java
