GoogleSignatureVerifier error: signature not valid when call requestIdToken!

[EdisonNguyen]

Hello Google team,

I face with problem when trying to getIdToken for my app flow:

https://developers.google.com/identity/sign-in/android/backend-auth#send-the-id-token-to-your-server

Every thing fine except requestIdToken(getString(R.string.server_client_id)). Our app will return error like:

05-24 19:17:40.091: V/GoogleSignatureVerifier(14539): com.vgames.gungunonline signature not valid. Found:
05-24 19:17:40.091: V/GoogleSignatureVerifier(14539): MIIDXzCCAkegAwIBAgIEBNOpETANBgkqhkiG9w0BAQsFADBgMQswCQYDVQQGEwJ2aTEMMAoGA1UE

...

I saw that this problem posted in Google + stackoverflow from 13 May. Until now no good answer for us.

I think my problem the same with: http://stackoverflow.com/questions/37333220

Could you check and give me your advice.

I tested in: SignInActivity googlesamples checkout 22 - May.

Thanks,
Tài Hải

@EdisonNguyen you can ignore the GoogleSignatureVerifier errors in logs. That's something that was meant for internal consumption and we accidentally left the logging on in the public release.

Are you having any other issues with your sign in flow, or are you just worried about that error?

I saw this error today and found maps to longer work in our app. Can't tell whether there's a connection or not. We're using maps v2.

// Edit
Ignore above comment. Was issue at our end.
