how to get android app_id from google play services

Question

I created android application and hosted it on google play, but suddenly I deleted my project in Eclipse (from disk too) and now I am restoring some files from backup but I don't have old app_id in res/values/strings.xml

how can I get app_id from play services or .apk or keystore because I need it for Google API integration

 <meta-data android:name="com.google.android.gms.games.APP_ID"
            android:value="@string/app_id" />

Answer 1

Sign in to the google developers console here: https://play.google.com/apps/publish

You should be able to find it under your app.

EDIT: It's in the Games Services tab

Answer 2

For the redesigned google play console (2020), click the Play Games Services, then click setup and management, then click Configuration. You will see information about your app, one field which is Authorization, and there you will find the application ID.
