Android Question Help with resource file based on Game Services

[DevBaby]

For Google's game services I have an App_ID, 4 Leaderboard IDs, and 27 Achievement IDs

Googles directs me to create a res/values/ids.xml file to add these ids. However, I do not know how to add the ids in the...for example, What is an achievement_* resource?

The instructions state....

To run the game, you need to configure the application ID as a resource in your Android project. You will also need to add games metadata in the AndroidManifest.xml.

1. Open res/values/ids.xml and replace the placeholder IDs. If you are creating an Android game from scratch, you will need to create this file first.
   1. Specify your application ID in the app_id resource.
   2. Specify each achievement ID that you created earlier in the corresponding achievement_* resource.
   3. Specify each leaderboard ID that you created earlier in the corresponding leaderboard_* resource.

The file ids.xml looks like

<?xml version="1.0" encoding="utf-8"?>
