Google play games not working

hi,
I can’t get google play games to work on my app.

those are my blocks:

now when I click the sign-in button, I get the same results as @ravigarg

and when I click the unlock achievement button (or the submit score button or the show leaderboard button) nothing happens.

now I tried this tutorial (even though it’s broken with all the pictures, I followed it, and its still does not work):

did anyone got google play games to work and can help me figure out how to get it working?

thank you for everyone who reads my post!

Can you provide a .apk?

Have you put the correct archievement ID?
