I am using Google Play Games Sign In implementation in my app but it fails with the error below:

 java.lang.VerifyError: Verifier rejected class com.google.android.gms.auth.api.signin.GoogleSignInClient: int com.google.android.gms.auth.api.signin.GoogleSignInClient.zzabd() failed to verify: int com.google.android.gms.auth.api.signin.GoogleSignInClient.zzabd():

the error occurs in this part of the code:

public void performGooglePlayServicesConnection() {
    GoogleSignIn.getClient(this,GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN);
    Intent intent = signInClient.getSignInIntent();
    startActivityForResult(intent, RC_SIGN_IN_GOOGLE_PLAY_GAMES);
}

What could I be doing wrong?

The suggested workaround in this link is to clean out the build folder resolved the problem.

Running a gradle clean task was not clearing out my build folder all the way. I had to do it manually, but clean may work for some people.

It is also recommended that if Clear project doesn't work, try with File -> Invalidate Caches / Restart... -> Invalidate and Restart.

I was also facing the same error.I missed to Configure Google API Console project. So Configure Google API Console project following this and specify your app's package name when prompted. You will also need to provide the SHA-1 hash of your signing certificate. See Authenticating Your Client for information.
