Q: Google Play Services Sign-in failed to complete I'm trying to implement Sign-in in my game. 
After I start my game Sign-in starts, I can see text "Google Play Games" on a green background with a logo above it, after that loading spinner starts to spin and shortly after that Sign-in fails, it just exits from Sign-in without any message.

A: Can you share the log from logcat?
Typically this is due to a configuration problem.  Double check:


*

*The game_ids.xml has been updated with the values from the Play Developer Console.

*Confirm that your packageName (or ApplicationId in the build.gradle) matches what is configured for the linked Android application for your game.

*Confirm that the SHA1 fingerprint is for the keystore you are using to sign your application matches the one entered in the linked Android app.

*Confirm that the default player on your device is added as a tester for your game.
