Yeah - I'm mixing the two up. I've sorted the Apple Game Center leaderboards - It's the Google Play Services leaderboard I'm trying to implement for Android.
I've got the Google Play Console and have created an application in the All Applications tab.
In the Game Services tab I've added a new game and created a Leaderboard.
It says the next step is for me to link an app.
When I click Link App icon I get a series of icons (Android, iOS, Web, Chrome, Other Platform) - I choose Android and it asks me for a package name - this is where I'm up to and where I'm stuck.
Can you help here?
