build.gradle

The play core library has been changed and separated into different libraries:

https://developer.android.com/guide/playcore#include_playcore

Please specify in the codelab tutorial on step 3 which of them I need to import.

Start with build.gradle and the codelab tutorial's step 3, then compare the Play Core library options in the linked Android documentation. Update the tutorial to name the required library or libraries to import, and verify that the dependency guidance matches the current Play Core separation.
