Answer 1

If you are created SHA1 code from custom keystore use the same in release mode. or generate apk by signing with that same keystore and test.

Before that you need clear app data (Setting->App-select app-Clear data->uninstall) and try. this worked for me. Ensure that package name is same as that in google developer console.
