4.27.2 Android Packaging Error 'java:372: error: cannot find symbol'

Hey, thanks for the reply bro. I solved the issue, it was due to 2 lines that I added in node tags. * com.google.android.gms.games.APP_ID=“@string/app_id” and com.google.android.gms.appstate.APP_ID=“@string/app_id”. According to this thread ’ Integrate Google Play Services with Blueprint - #2 by OmniOwl ’ . I removed those lines and the packaging worked but I still cannot find a way to implement Google Play Services to my game.
Do you have any knowledge on how to do that? If you do please tell me.
