Google Login does not work after posting to the Play Store

My code is all right. When I use the application from an emulator, or generating APK and installing on the devices the login with google account is done perfectly. The problem came up when I was posting on the playstore, suddenly my login with google stopped working. When I click to login, the google message appears to choose an account, I choose one and nothing happens. This is the second time this has happened. When I publish on the playstore it crashes. What can I do? What am I doing wrong?
