What do you mean by signed APK? I created the Android key and signed the app. Do I have to do something else to sign it?
Means.. You need to upload your game and publish it at your google play developer account. And then you can sign-in to your leaderboard.
If you try to sign-in from an apk which just export and build it and you have on your desktop, this action not work.
1. Upload apk at your google play developer account
2. Publish it as alpha, beta or normal
3. Test it
