The Google Play Developer console provides great game services. It also has a feature to export the resources, such as Leaderboard IDs and Achievement IDs, to Android XML and other formats.
None of this helps the Unity world. This tool will allow you to take the TEXT format resource export and import it into your Unity project to generate a C# class with all resources defined as constants.
Save time quickly importing all your defined resources
Avoid typos and copy/paste errors with constants
