Add support for Androidx instead of using support library #623
Description
AndroidX will replace the Support Libraries.
AndroidX is the open-source project that the Android team uses to develop, test, package, version and release libraries within Jetpack.
AndroidX is a major improvement to the original Android Support Library. Like the Support Library, AndroidX ships separately from the Android OS and provides backwards-compatibility across Android releases. AndroidX fully replaces the Support Library by providing feature parity and new libraries.

AndroidX is the replacement for Google Support Libraries. Android P is the transition phase for this. The next version of Android is likely to support only AndroidX. This library fails on android builds that use the new compileSdkVersion.
