downloaded Google plus sign-in example application from here: https://developers.google.com/+/quickstart/android
But when I click on GooglePlus button, I received error all the time:
ConnectionResult.getErrorCode() = 4
Why it occurs ?
On this page there is Troubleshooting section :
If you are seeing ConnectionResult.getErrorCode() = 4 when trying to connect, ensure that the consent screen is configured and saved.
What that means ? What should I do ?
