And Android Sdk Tools: November 2016 Android Sdk Google Repository , Android Support Repository And Extras Update

This month we got update on SDK Extras and some breaking changes.

This might not a big deal if you are install the package regularly. However for offline installation you need to be aware of the new package naming on Google Play Services and Google Repository.
The actual major version listed in the SDK Manager is 37 and 38 BUT on the downloaded package name  they have package names:
-google_play_services_v7_rc28.zip
-google_m2repository_gms_v7_rc28_wear_2a3.zip

yep, "v7" on the .zip package is bit weird naming IMHO. But actually they are valid package for version 37 and 38.

No need to worry because we've update  the post with How to install the package :
