AndroidX Test Library
Denys Zelenchuk · Apress eBooks · 2019
A May 2018 Google I/O event announced the AndroidX open source project, which is used to develop, test, package, version, and release libraries within Android Jetpack. AndroidX replaces the Android Support Library. One of its major improvements is the fact that AndroidX packages are separately maintained and updated, so you can update AndroidX Libraries in your project independently.
